The heavy-duty Timbren Axle-Less system combines Timbren's standard 3,500-lb Axle-Less system components with 2,000-lb AEON rubber springs, giving you a suspension system that is perfect for your small, off-road trailer. It allows you to use parts that would typically only fit a larger trailer on your undersized trailer. Add brakes for improved control. Get greater ground clearance and increased durability by installing bigger tires and wheels. The reverse drop spindles deliver even greater ground clearance and give you the ability to use larger tires than you could with a standard straight spindle. This makes the heavy-duty Axle-Less suspension system ideal for off-road use.


Note: The Timbren Axle-Less suspension system may require additional support on your trailer. If your trailer does not have a crossmember above the spot where you want to install the Timbren system, you may need to reinforce the frame. You can accomplish this three ways. First, you can retrofit the trailer with a crossmember. Second, you can build out the trailer frame. Third, you can use standard, 2-inch by 3-inch steel tubing to connect the 2 Timbren suspensions together using the built-in hole on each unit.


Ground Clearance

Ride on rubber with Timbren's Axle-Less trailer suspension system. This one-of-a-kind suspension consists of two separate units, each containing rugged steel arms and two strong, hollow rubber springs. Overall, the system safely and effectively absorbs road shock, minimizes trailer bounce and rattle - regardless of load size - and helps to protect your trailer's components and cargo. Built-in camber and toe-in keep your trailer tracking straight to minimize tire wear. Integrated hangers attach to your trailer's frame. And 2-inch by 3-inch holes make it easy to reinforce your trailer's frame by adding standard, 2-inch by 3-inch-steel tubing (if needed).


The Axle-Less independent suspension system replaces your trailer's existing leaf spring suspension and can eliminate the need for an axle. The independent action of the suspension reduces roll when your trailer is cornering and allows you to maximize ground clearance and minimize deck height. Your trailer can have the same side-to-side clearance as your tow vehicle. And the low deck height makes it easy to load cargo from either the rear or the side.


Because you're riding on rubber, your trailer will ride smoothly and comfortably, whether you're navigating rocky terrain or highway asphalt.


Timbren Axle-Less Suspension Parts

Components

  1. The AEON progressive-rate main spring supports the weight of your trailer and cargo and easily absorbs road shock. It is constructed of heavy-duty, hollow rubber.
  2. The rebound spring minimizes trailer bounce, rattle and bottoming out. It keeps the suspension under constant tension and ensures that the main spring compresses and expands in a controlled fashion. And it delivers a smooth, stable ride - regardless of how much cargo is on the trailer.
  3. The trailing arm and integrated hanger attach the suspension to the side and bottom of the trailer frame.
  4. The control arm carries the spindle and the hub. It pivots on strong, long-lasting urethane bushings that never require lubrication.
  5. The EZ lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money. The spindle also includes a 5-bolt brake flange for simple mounting of trailer brakes.
  6. The hub is not included with this model.
  7. The built-in hole accepts standard 2-inch by 3-inch tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2-inch by 3-inch steel tubing through the hole on each suspension unit and then bolting the tubing into place.

Timbren Axle-Less Suspension versus Leaf Springs

Leaf Spring Example

The Axle-Less suspension's progressive spring is a definitive upgrade over leaf springs. Although leaf springs deliver a stable ride when supporting a load, a trailer with leaf springs will bounce and rattle when it's empty or supporting a light or off-center load. On the other hand, your trailer can bottom out on bumpy roads if the load is too heavy. The AEON progressive-rate springs of the Axle-Less suspension always deliver the same reliable performance, no matter the load size. As more weight is added to the trailer, the springs compress and become stiffer, offering more support for heavy loads. And because they rebound more slowly than leaf springs, the AEON springs do a better job of absorbing road shock, thereby keeping your trailer from bouncing and rattling when you're carrying a light load. So with this versatile system you will enjoy a smooth ride whether you're towing an empty trailer or a hefty load.


Unlike leaf springs, Timbren's Axle-Less suspension units operate independently of one another. Each spring activates only when needed. This reduces roll and delivers top-notch performance, even when you're hauling off-center loads. When your trailer with leaf springs takes a turn, one side of the suspension compresses and takes on more weight, and the other side becomes looser and bounces. This causes rattle and can make the trailer lean to one side. But when your trailer with the Axle-Less suspension takes a turn, one side compresses and becomes more rigid to absorb the weight, and the other side expands to normal height to help steady the load and minimize bounce and rattle. The load stays better balanced, even if it is off-center.


Timbren Axle-Less Suspension versus Torsion Axles

Torsion Axle Example

Timbren's Axle-Less trailer suspension system is a great alternative to torsion axles. While both systems allow either side of the trailer's suspension to operate independently, only Axle-Less suspensions are actually separate units. Torsion axles still require a bar that spans the bottom of your trailer, whereas Timbren's system can eliminate the need for a thru axle - giving you the same amount of ground clearance from the front of your trailer to the rear. It also allows Axle-Less suspensions to fit any trailer width - unlike torsion axles, which have to be fitted to an exact frame width.


Axle-Less suspensions operate in a smoother, less stressful manner than torsion axles. Torsion axles use a twisting motion, where the bar inside the axle tube rolls against rubber cords or a rubber wall to create compression and resistance. The up-and-down motion of the main spring and the side-to-side motion of the rebound spring in Timbren's Axle-Less suspension work together to provide smooth, consistent compression - with no twisting - that results in a better ride and less stress on the suspension's components.


Installing the Timbren Axle-Less Suspension

Whether you are building a trailer or retrofitting your existing trailer with the Axle-Less system, you must make certain that the trailer's frame is both perfectly square and sturdy enough to support a heavy load without the aid of a thru axle.


Install Option 1

There are three ways to install the Axle-Less suspension. The easiest method, which is recommended if you are replacing axles on your trailer, is to install a piece of 2-inch by 3-inch tubing (sold separately - available at most weld shops) through the integrated hole in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with three bolts (not included).


Install Option 2

The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.


Install Option 3

The third method of installation is to bolt the Axle-Less suspension's hanger to the trailer's frame and to an existing crossmember that is in the area where you want to install the suspension.


With both the second and third options, you must use three bolts to attach the suspension to the side of the frame. And you also have to use two or three bolts to attach the suspension to the bottom of the frame extension, or crossmember. Both the second and third methods of installation will eliminate the need for a thru axle and provide the most clearance.


Measuring Diagram

Timbren's Axle-Less suspension units should be installed directly across from one another. Before mounting the units, measure back from the coupler and mark the frame to make sure that the two distance measurements (A and B) are within 1/8 inch of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, half-inch bolts (not included).

Fast service from etrailer sending me my Timbren kit. They are always very helpful. Unfortunately it looks like UPS mishandled one of the 3 boxes and had to re-tape it all over. I just rcv'd the shipment, so I will have to open the box when I get home and make sure everything is inside. This is no fault of etrailer, just the shipping companies these days.

Review from a similar Axle-Less Suspension in Trailer Axles


The trailer rides great down the road and no more worries about saltwater and rusty leaf springs. Not a cheap option but I’m very happy with the setup. When installing, just be sure to measure accurately and have sharp drill bits. A drill press type of guide also helps ensure correct drilling angles. The first picture is of a mounting gusset a local welding shop made. One is needed for each side and necessary to provide needed mounting strength-at least on my trailer frame. Pics 2 and 3 show the mounted suspension on one side of the trailer. Pic 4 shows the suspension on one side of the trailer with the axle attached and a separately purchased disc brake assembly mounted on it. Finally, pic 5 shows a 2” box channel between both suspension assemblies. Independent suspensions would have been nice, but I wanted to ensure trailer rigidity was maintained. So, after one year, so far, so good. It’s all smooth sailing down the highway.

Actually over a year, and still working great.

Review from a similar Axle-Less Suspension in Trailer Axles


They have more pros than cons, but the second set I bought broke the flat plate that holds the spindle at about 8 months. The steel quality seemed less than I would expect since it basically peeled it back like a pop can as you can see in the pictures. Otherwise I like the clearance and ride. They last 2-3 years where the torsion axles I replaced would wear out in 4 months after driving down rough gravel roads. There is a grade zerk on the underside which I didn't realize until I bought the second set. That would have helped the first set last longer had I known about it.

Review from a similar Axle-Less Suspension in Trailer Axles


I used these axles in a different way than most would. I needed a trailer that was small, could handle tight switch-backs, carry 600 lbs and be light. I had this idea and as a retired design engineer I saw a great possibility in this axle. I have made four of these trailers now, one as a camp trailer, 2 for trail work for State Parks and one as a utility trailer.

Review from a similar Axle-Less Suspension in Trailer Axles


I am not a mechanic so Brandi was real helpful. Had to get some professional help to remove the old suspension and install the new suspension. The only drawback we ran into was the spindle did not extend out far enough to mount the tires in the normal way. We had to put the tires on backwards. It all worked out beautifully. Towed the trailer for over 1700 miles without any problems. Brandi was delightful to talk with and very patient with me. Her help was most appreciated. Sorry, I didn't take any pictures.

Review from a similar Axle-Less Suspension in Trailer Axles


Very exicited about these axels, I have been eyeing these for over a year. (Excellent service from etrailer, they had my parts to me in 1 day from the time of placing the order.) These axles seem to be well made and fit nicely with the Dexter hub and drum assembly and the 12" electric brake kit. I installed this all on a M1101/M1102 trailer frame after removing the factory axel assembly. I have not ran these on the road or off as of yet but will give another review at that time. The fit and finish are great and the packaging was good, a little banged up from shipping (missing 1 washer)

Review from a similar Axle-Less Suspension in Trailer Axles


Purchased 2 sets of the Timbren 1200 Axle-less systems for upgrading the suspension on an older 30' ft glider trailer. Single axle with small (13") tires made towing tough due to porpoising, dragging on drive entrances do to poor flotation; also German made and metric, no repair parts. GVW 2000 lbs equated to bouncy ride. Dual sets now allow the trailer to ride over bumps and sharp inclines easily, smoothly, little bounce on country roads; porpoising is history. My glider now rides securely, safely, quietly. Install time 4 1/2 hours (includes head-scratching). Results are outstanding, units are totally solid. Recommend the square tube interconnect, easy and quick - trailer frame was on the light side, so a precautionary fix. Clean look underneath. Ordered 5 wheels w/tires, very nice. Helpful neighbor so impressed he ordered a HD single set for his new DIY snowmobile trailer. Customer satisfaction 100%, from phone order, online support, product information, immediate shipping, install instructions, followup... HIGHLY RECOMMENDED!


Comments
I have just a little more to add regarding my purchase: Two sets, of the Timbren Axle-less assemblies, 1200 lb, and 5 wheels. I placed the order via phone, and whoever was on-call that day provided great answers and recommendations regarding the units, wheels and tires. At 31 feet, the trailer originally exhibited amplified porpoising on any bumps or dips in the road. Also bouncing and occasional sideways tipping due to the single axle. It made a lot of noise on my mountain community washboards. I speculated that the Timbren units would solve most, if not all of these problems and they have. Installation on my older 31 ft European ie, metric and no longer manufactured glider trailer was a mere 4.5 hours from removal of the old single axle to setting the trailer back down on its new assemblies. Instructions are complete, precise, useful and helpful. Appreciated. Little to comment on as installation was all straight-forward. I would like to describe the maiden voyage to the airport and back, but there is nothing to tell, other than it towed beautifully proper alignment instructions, and all that I viewed from the rear view mirror looked like a magic carpet ride. It rides over washboards and pot holes like a marathon hurdler, the 4-wheel independent suspension is great. Packaging: the shipping boxes all arrived in good condition, but the cardboard component boxes inside them... not so much. Most were ripped and open due to heavy components lightly surrounded with brown packing paper, just token amounts. Parts: all was accounted for minus a pair of spindle axle washers for one set, easily replaced at the local farm and ranch supply. No squawk, just an fyi. I am very pleased with your product and support, and was happy to leave a 5-star review with photos. The upgraded suspension was also a topic this past weekend at the glider port by those who regularly trailer their ships to various soaring events, some as far as a thousand miles away. My compliments to eTrailers, hope you can use my info,

Review from a similar Axle-Less Suspension in Trailer Axles


Timbren saved our RV road trip! The leafs on the axle on our 2018 Jayco TT came apart while driving in Maryland. We tried going to the manufacturer, but they were useless. Going to a RV mechanic meant being grounded for at least 2 months. Then we found Timbren. With the help of Timbren's excellent staff we purchased axle-less system through etrailer, who made sure we got as quick as possible. It came ahead of schedule, my husband installed the Timbren system and we were back on the road! The axle-less system is better than the original manufacturers. If you plan on taking your RV or TT farther than 100 miles GET THIS INSTALLED and get it through etrailer.

Pleased with ETRAILER, will order here again. Not as happy with the torsion axle setup. 2 inch square opening for tying both axles together with your own 2" square tubing are not shaped to match 2x2x1/8 tubing. Grinding and welding of tubing required to make it fit. Also found the overslung stub axle left the end of the pivot arm without much ground clearance though the unit was intended and spec'd for atv tire off road use. A pivot arm with mounting pads top and bottom would be better and allow the user to choose high or low clearance use. I found the units were perfectly suited to offroad use once I fabricated new mounting pads and welded them to the bottom of the arms.


Comments
After a year of off road use, I couldnt be happier. My trailer rides smooth loaded or unloaded. No of that bunny hopp with leaf springs or rigid mount axles. The small rebound control snubber works perfectly! I modified my components for high clearance but the concept is sound, they work well. Great job Timbren!

The order came in on time and the customer service at etrailer.com (Ashley) and Sean from Tmbren was outstanding. They both were very helpful in my choosing the right product for my needs. The axle less suspension's performance is absolutely superb. It vastly improves ride quality. I am using it on a teardrop camper that often goes on gravel roads and the raddling sound from the leaf axles was horrible. A couple of points to consider before you settle on the axle less suspension: keep in mind that you will lose some hight of the trailer. While you will gain clearance from the lack of the axle, the suspension will make the trailer sit lower than before.i had to lower my hitch by an inch to maintain the trailer leveled. Also it does appear to compress at higher rate than the leaf springs, which makes it softer but easier to reach it's limit. Overall this product is absolutely a must if you are looking to improve the safety and the quality of your towing.

Review from a similar Axle-Less Suspension in Trailer Axles


These units install easily, are well made, and perform great! The trailer doesn't bounce around like you see a lot of trailers do while traveling down a bumpy road. I traveled some unpaved roads with no issues. I am certainly glad I went axleless. I installed with 15" tires. Problem is I didn't go big enough. I intended to install on an existing trailer that I had. Changed my mind and built a new trailer. The new trailer came in heavier than I had planned. 2k pound capacity is now too small. I have to watch what I load the trailer with so I don't over load the suspension. I intend on buying the 3500 pound units when I have the money.

Review from a similar Axle-Less Suspension in Trailer Axles


I installed these on my single axle travel trailer to replace the axle and leaf springs. Weight savings was a wash with the required steel tube for added stability. I installed on an I-Beam using aluminum plate as a spacer. It took my friend and I 3 days to install everything. The hardest part was rerouting my black pipe propane line. I also had to install it just back of center due to a steel cross beam being in the way of the middle bolt hole. I replaced the brakes and hubs as well as the wheels to match the new hubs. Overall we've been super happy with this upgrade. The trailer rides a lot smoother. I'm not finding random screws on the floor after a long bump ride. We decided to do this after our leaf spring broke 2 times, 12k miles between. We were done dealing with a subpar suspension. I probably would not recommend doing this if your leaf springs are working for you. We put a lot of miles on our trailer. We aren't weekend campers.

Review from a similar Axle-Less Suspension in Trailer Axles


After a great deal of research, I ultimately chose the Timbren long arm kit to replace the torsion axle under my teardrop trailer. My initial impression is that there is simply no comparison between the two. It now rides better, pulls better and handles better than I could have imagined. The Timbren axle system is incredibly well built and is much more confidence-inspiring. While the spring rate closely matches my trailer weight, the components are much more rugged and robust. The spindles, bearings and brakes are rated at double the capacity of my old axle which gives me great peace of mind. I pull my trailer, both on and off road, anywhere it will fit and the long travel and heavier components are a game-changer for my travels. Installation, while requiring a bit of forethought, was otherwise straightforward and methodical. Documentation available from etrailer and Timbren, is second to none. Instructions were clear and concise with drawings and detail taking the major guesswork out of the equation. Even though, due to the odd frame design of my trailer that required a bit of work to adapt, I ended up making some frame stiffeners, the adaptation was as simple as it could possibly be. I've ordered from etrailer in the past and they were 100% accurate on this order as well. I ordered the Timbren kit without backing plates and hubs due to the requirements of my trailer and etrailer suggested, explained availability and supplied all of the components I needed. They truly a stress-less bunch of folks with an extraordinary website. I'll no doubt turn to them again...

This suspension system did EXACTLY what I wanted. I replaced the leaf springs, axle/hubs on my small trailer. The new suspension improved the capacity, lowered the bed 4+inches, improved ground clearance and allowed me to rebalance the trailer all WITHOUT having to have any welding done. Everything needs to be measured very exactly and the alignment technique is fairly cumbersome and takes a bit of time. In the end, I have a quiet, steady, strong, low riding trailer.

    I apologize for the confusion on that but the Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR35HDS05 that you referenced is rated for 3,500 lb as an axle. Each of the springs on either side of the kit has a 2,000 lb capacity. So spring capacity-wise this has an overall 4,000 lb capacity but the spindles and other components are the limiting factor at 3,500 lb.

    The Timbren axle-less suspension kits are offered in either 4-on-4 or 5-on-4-1/2 bolt patterns; none is available with a 8-on-6-1/2 pattern idler hubs. All such kits are shown on the linked page. Several of these 3500-lb kits, parts # ASR3500S06, # ASR35HDS05 and # ASR35HDS02, offer the 4-inches of lift you want and come without hubs. You can use an idler hub or a hub/drum that takes the same inner and outer bearings.

  • Recommended Axle and Suspension System for 2015 Rockwood Freedom 1940LTD
    For your 2015 Rockwood Freedom 1940 LTD, I recommend the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Regular Tires - 3,500 lbs # ASR35HDS05. This will give you the suspension components integrated into the axle-less spindles. With this kit, I recommend the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA along with the Trailer Hub and Drum Assembly - 3,500-lb E-Z Lube Axles - 10" Diameter - 5 on 4-1/2...

  • What is the Load Capacity of the Timbren Axle-Less Trailer Suspension?
    The Timbren Heavy-Duty Axle-Less Trailer Suspension - 2,000 lbs # ASR2KHDS01 has a total weight capacity of 2,000 lbs instead of an individual capacity of 2,000 lbs each. For something that will give you greater capacity for your cargo, I recommend the Timbren Heavy-Duty Axle-Less Trailer Suspension - 3,500 lbs # ASR35HDS05. The 3,500 lbs weight capacity of this system will be what allows you to move the cargo you plan to haul. I've added a link to a video review of this product for...

  • Will Timbren Axle Less Kit Installed on 1/8 inch Thick Frame Rail Require Additional Bracing
    Sounds like your frame dimensions would be thick enough to handle the install of the # TASR5200S05 since it's 1/8 inch thick steel channel. It is harder to say though without seeing the frame and it's design aside from thickness. You might check with a local fabricator to see if they agree, which I think they will, if you wanted to err on the side of caution.

  • How To Find Correct Timbren Axle-Less System for 7K Trailer with Mobile Home Axles
    The mobile home axles are a one time use so we don't really carry parts for them and the old design would make it very hard to find much of anything for. The Timbren Axle-Less Trailer Suspension System would indeed be the best option for a complete setup, there are many options though. For a 7K trailer, two 3,500 lb axles would give you plenty of support since another 10-15% will be supported on the vehicle tongue. The part # ASR3500S05 is for a 3,500 lb axle and comes with a straight spindle...

  • Timbren Axle-Less Suspension System with Electric Brakes for a 3,200 Pound Trailer
    In the trailer world there is no 5 on 6-1/2 bolt pattern. And besides that trailer tires and wheels are not rated for use on a vehicle just as vehicle tires and wheels are not rated for use on trailers. The issue is that trailer tires are built with a thicker sidewall than passenger vehicle tires. The thicker sidewall can handle more vertical load but do not work well when lateral forces are applied to them such as when on the turning axle of a vehicle. So you can use an Axle-less suspension...

  • Recommended Timbren 3,500 Axle-Less System with 4 Inch Lift Spindle for Lance Trailer
    The only real difference between the Timbren Heavy-Duty Axle-Less Trailer Suspension with 4" Lift Spindle - 3,500 # ASR35HDS05 and the standard Timbren # ASR3500S06 is that the Heavy-Duty model features a larger spindle that would accommodate larger hubs and wheels. I am not sure why Timbren would have suggested the Heavy-Duty model for your application but the standard Timbren # ASR3500S06 features the capacity you need, the lift you are wanting, and would allow you to retain the use...

  • Will 16 Inch Tires Fit Timbren Axle-Less Suspension System # ASR35HDS05
    As long as there is a hub that fits the spindle and has the bolt pattern needed for the wheels then yes the Timbren Axle-less system # ASR35HDS05 will work with 7.50-16 tires. For example hub # AKIHUB-655-6-EZ-K will accept 16 inch tires as long as the wheel has a 6 on 5-1/2 bolt pattern. I have linked a help article on determining wheel bolt patterns for you.

  • Timbren Axle Less Kit for Trailer that Weighs 3,045 lbs
    Since your trailer weighs 3,045 lbs when loaded the 3,500 lb Timbren Axle Less kit part # ASR35HDS05 would be perfect unless you though you were going to eventually loaded down beyond 3,500 lbs. Then you'd want the # TASR5200S03 which has the higher 5,200 lb capacity. If you end up with too high of a capacity your ride quality might be a bit rougher.

  • Recommended 4 inch Lift Spindles or System to Raise Deck Height of Trailer
    For your specific application, we really only have one style of trailer axle and suspension that will work with your spring center to spring center dimensions. It is the Timbren Axle-Less Trailer Suspension System with 4 Inch Lift Spindle. This is available in 2000 lb # ASR2KHDS04, 3500 lb # ASR35HDS05, and 5200 lb # TASR5200S03. These can be used in tandem axle applications as well. Most snowmobile trailers will have a 3500 lbs axle when using 15 inch wheels if you want to be similar...

  • Can I Use Idles Hubs Instead of Drums on the Timbren Axle-Less Trailer Suspension
    Yes the Dexter Trailer Idler Hub Assembly for 6,000-lb E-Z Lube Axles part # 8-213-51UC1-EZ will work with the Timbren Heavy-Duty Axle-Less Trailer Suspension part # ASR35HDS05. I was able to confirm that they use the same bearings. The reason that they say they are for drums is that typically there are brakes on larger trailers like what the spindles are designed for.

  • Timbren Axle Less Kit that Can Fit Jeep 5 on 5-1/2 inch Bolt Pattern Hub
    The 3,500 Timbren Axle Less kits like the part # ASR35HDS05 you referenced actually have 6k spindles on them so for hubs you have to go with the higher rated setups which unfortunately don't have any options in the Jeep bolt pattern you need. Could you get by with a lower rated Timbren Axle Less like the part # ASR1THDS03 which is a 2,200 lb axle and has 3,500 lb spindles so the hub you mentioned # 84555UC1-EZ would fit.

  • How to Choose Replacement Axle for Trailer With Mobile Home Axle
    We are going to have parts that will work for you, though the issue is your current mobile home axles; these are designed for one-time use (to move mobile home from Point A to Point B) and should not be used continually so you will need to replace them. In order to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center as in the diagram I have added; the other thing you need...

  • Are 3,500 Timbren Axle-Less Suspension System w/ Lift Weight Capacities for One Side or Both
    That's a good question, and the weight capacities for the Timbren Axle-Less Suspension Systems are for the set (both sides). Just think of it like a normal axle with a 2,000 lb rating being for the entire axle as opposed to just a single side. So because you mentioned your fish house frame was 2,500 lbs semi-loaded you would definitely need to go with a 3,500 lb system. This application can work, it just installs by bolting onto your frame, though you do need to ensure there is enough...

  • Lifted Axle Setup for Trailer with 3,000 lb GVWR

  • Recommended Suspension and Axle Upgrade For 2018 Grand Design 2800BH
    I have another option for you, but Trailer leaf springs are not designed for off-roading and can break when used in rough off-roading conditions. I do have a great option for you which is the Timbren Heavy Duty Axle-Less Suspension System # TASR35HDS04. This system has a 3500lb weight capacity which matches your current axles, but being the heavy duty version they are made of thicker metal making them a great option for off-roading.
