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 3 ways. First, you can retrofit the trailer with a crossmember. Second, you can build out the trailer frame. Third, you can use 2" x 3" 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 2 separate units, each containing rugged steel arms and 2 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" holes make it easy to reinforce your trailer's frame by adding 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.
  6. The hub is not included with this model.
  7. The built-in hole accepts 2" x 3" tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2" x 3" steel tubing through the hole on each suspension unit and then bolting the tubing into place.

Timbren Axle-Less Suspension vs. 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 vs. 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 3 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" x 3" tubing (sold separately - available at most weld shops) through the integrated holes in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with 3 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 3 bolts to attach the suspension to the side of the frame. And you also have to use 2 or 3 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 2 distance measurements (A and B) are within 1/8" of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, 1/2" bolts (not included).

Good application for custom axle set up that would not allow mounting to outer frame. Suspect I will need to make adjustment to camber as these mount to inside of frame with wheels in rather than outside of frame but shims were provided with kit. Also confirmed with mfg., Timbren, that these could be used in that configuration. Parts arrived in good condition in timely fashion. Did received two different type of tires but that was easily resolved with a single email. Good company to work with, competitively priced.

Review from a similar Axle-Less Suspension in Trailer Leaf Spring Suspension


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 Leaf Spring Suspension


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.

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 Leaf Spring Suspension


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.

Review from a similar Axle-Less Suspension in Trailer Leaf Spring Suspension


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 Leaf Spring Suspension


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...

Review from a similar Axle-Less Suspension in Trailer Leaf Spring Suspension


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 Leaf Spring Suspension


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!

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.

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. What more could you ask for

  • 7k Timbren Trailer Axle that Gives Lower Profile
    It's hard to give you an exact deck height you'd have with the Timbren Axle Less kits we offer like the part # TASR7KS01 as it depends on the wheel/tire size you use and frame height, deck thickness etc. But if you are looking for the lowest profile possible the 4 inch drop version part # TASR7KS02 is the kit for you.

From there you subtract the width of your wheels and the length of your two spindles. This will give you the necessary axle tube length.

If you want to pursue the steering axle you will need to check with your local DMV for requirements. My recommendation is to use a single or tandem axle application for each trailer. If you want to use a single axle for your 7K trailer, I recommend the Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange - Regular Tires - 7K...

  • Recommended Suspension to Replace 5,200 lb Axles
    Before potentially upgrading, you'll need to use your trailer's VIN and contact the manufacturer to ensure it can handle the extra capacity you're looking to add. If so, you can upgrade by using the Timbren Axle-Less Trailer Suspension System # TASR7KS01 which has a capacity of 7,000 lbs and will replace your traditional axle. These suspension units can be bolted or welded to your trailer, though if you do not have a crossmember above the area you are going to install the Timbren, you might...

  • Axle Replacement for Dexter SLR P12 #13 Torflex Axle
    It took a little while to get your information from Dexter. Your axle is a #13 Torflex Axle which is rated for a capacity of 8,000 lbs. We don't have an 8,000 lb capacity replacement, but we do have 7,000 lb capacity Axle-less Systems you may want to consider or tandem axle applications to get you to your capacity needs. For the Axle-Less system you may want to consider the Timbren Axle-Less Trailer Suspension # TASR7KS01 or the 4 inch drop axle # TASR7KS02. These will allow you...

    The Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange # TASR7KS01 is designed to be used with 8 lug trailer hubs part # 42866UC3-EZ. This is a 7k axle kit that would work well. For brake assemblies then you'd want the part # 23-324 for the left hand side and part # 23-325 for the right hand side and you'd be set.

  • Recommended Timbren Axle-Less Suspension with Parking Brake Operated by Hand
    I recommend the Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange - Regular Tires - 7K # TASR7KS01 which are the highest rated capacity axles we carry. With this you can use the Dexter Electric Trailer Brake Kit w/ Parking Brakes - 12" - Left and Right Hand Assemblies - 6K # 23-112-113 which will work fine with the 7K axle. Then you can use the Titan Breakaway and Parking Kit for Drum Brakes # T2385200 which will require you to make slight modifications for connection...

  • Weight Capacity of Timbren Axle-less Suspension Systems
    The Timbren Axle-less suspension systems are weight rated per axle. So the 7,000lbs is for the set. For your 13,000lbs trailer you would need to install 2 sets, so making your trailer a tandem axle. For example the 7,000lbs kit # TASR7KS01 has a quantity of one axle set. It has two pieces that equal one axle, a driver's side and a passenger's side. The # TASR7KS01 has a weight capacity of 7,000lbs. If you purchased a quantity of 2 # TASR7KS01, this will give you a weight capacity...

There are large capacity models like the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03 or the Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange - Regular Tires - 7K # TASR7KS01.

  • Can I Upgrade One Axle At A Time From 3500 To 7000 lb Capacity?
    I don't recommend upgrading one axle at a time. The capacity differences are substantial, and you will be limited to the weakest component. So the axle, the springs, the equalizer, the brake assemblies, and the hub/drum assemblies would all need to be accounted for. This axle capacity upgrade will require different brake assemblies, different hub assemblies, different suspension and different wheels based on the bolt pattern needed for this 7,000 lb capacity. There can be all kinds...

  • Determining Weight Capacity of Dexter Mobile Home Axle Using Serial Number
    I reached out to my contact at Dexter and with the serial number you provided was able to get some specs on your trailer axle. What you have is a 6,000 pound mobile home idler axle that features an 82.15 inch spring seat length and a 96.13 inch track length. It is important to note that mobile home axles are really only designed and built to be used one time. If this is what you have on your trailer I highly recommend replacing it with a standard trailer axle. We don't have any axles...

  • Rating of Axles on 2008 Forest River Cedar Creek Silverback 33LBHTS 5th Wheel Trailer
    The 2008 Forest River Cedar Creek Silverback 33LBHTS has a specified GVWR of 13,830-lbs. Since it is a tandem-axle trailer this means it is likely to have a pair of 7K-rated axles (it should, anyway!). The stock tire size specified is LT235/85R16E. We do offer beam axles but not ones rated as high as 7K. This is due to shipping size/weight restrictions. Typically a 7K axle has a hub face dimension of 89-inches and a spring center spacing of 74-inches. You can contact Forest River...

  • How Much Travel Distance Is Recommended for Fender Clearance with Timbren Axle-less Suspension?
    You can absolutely use Timbren Axle-Less Trailer Suspension System on a custom trailer application, however the instructions state that the axle-less systems are not recommended for triple applications. With whatever system you end up using, you will want to leave a minimum of 4-7/8 inches of clearance above the tires for the suspension travel. If you end up using these axles, I recommend the Trailer Hub/Drum Assembly - 5,200-lb to 7,000-lb E-Z Lube Axles - 12" - 8 on 6-1/2 - Galvanized,...

  • Recommendation for Trailer Axle on Wide Trailer
    We don't have a through axle anywhere near the length you mentioned for the width of your trailer. That would be a custom application for sure as manufacturers often have the 89 inch hub face to hub face as the longest measurement. Most states have a maximum width of 8 feet 6 inches, so I recommend you confirm with your state requirements. There will also be lighting requirements if over 80 inches. For your custom application, I recommend the Timbren Axle-Less Trailer Suspension System...

  • Will the Timbren Axle-Less Trailer Suspension System Work On a Keystone Montana with 7K Axles
    The Timbren Axle-Less Trailer Suspension System part # TASR7KS01 could be used to replace the axles and suspension on a Keystone Montana 5th Wheel Trailer. However, this would require changing the entire geometry of the suspension which is a rather complex install. If you are up for the task and depending on what you are wanting an axle-less system for this could be a viable option. There won't be any issues as far as weight capacity goes if that is what you are asking. That said, if...

  • How Do I Determine the Axle Spacing on My Trailer
    I can tell you how you can measure this, but unfortunately we don't have a database with that type of information on each specific trailer. Because of the varying weights on different trailers you can get different measurements between the axles and they won't always be 33" or even 35"; I've seen some that are different depending on the size of the trailer. To find the axle spacing on your 2003 Forest River Cedar Creek, all you really need to do is measure the distance between the two...

  • Can a Damaged Torsion Axle Be Replaced with Timbren Axle-Less Suspension
    Torsion axles use internal rubber cords to provide the suspension motion and they really are not practical to repair/rebuild. Certainly any axle that was damaged in an accident should be replaced purely for safety reasons. It is potentially possible that in certain cases the spindles can be replaced but that depends on the specific torsion axle and the specific damage. We do not offer torsion axles but we do have axle-less suspension kits from Timbren that completely dispense with the...

This kit comes with 2 full brake assemblies and has an 8 on 6-1/2 wheel bolt pattern. I have attached a helpful article that explains what is needed to add hydraulic disc brakes to a trailer you can check out.

  • Replacement Axle Assembly for 6,000 lb Torsion Axle Bend Spindle on 2012 ATC Car Hauler Trailer
    If just the spindle is bent, we have the #42 Spindle for 5,200-lb to 7,000-lb Trailer Axles - 2-1/4" Diameter # TRU57FR as a replacement. If you have more than a bent spindle then the other option is to replace your entire axle. Because you don't have the hangers and leaf springs for a thru-axle replacement, the best option we have is to replace your axle with the slightly higher capacity Timbren Axle-less system. I recommend using the Timbren Axle-Less Trailer Suspension System...

Either of these will work well on a gooseneck trailer application and will replace leaf spring suspension components as well. It will require a cross frame member at the axle location or a 2 inch square tube (not included) to be added to...

  • Are Longer Axles Available For Single Axle Pontoon Boat Trailer
    I did some research on your 1994 Sylvan Pontoon boat and found that the beam is 8-ft.

I have attached a photo that shows how the bunks are placed under the pontoons. If your trailer frame is wide enough to be able to place the bunks with those dimensions then you would not need to try and extend the axles. You may want...
