Specs:
Note: This Axle-Less system requires crossbeam support. If your trailer frame doesn't have a crossmember in place, you can retrofit it with one, or you can add a support by running a piece of 2" x 2" steel tubing through the square holes cut into these units. You could also add a steel reinforcement bracket to the inside of the trailer frame.
Get more ground clearance and a more comfortable ride when you're towing with Timbren's Axle-Less trailer suspension. This suspension system provides great shock absorption to comfortably get you where you need to go and to protect your precious cargo as you travel - even on rough pavement. With 2 independently operating units, you'll get better handling when making tight turns. And because this system eliminates your axle and has standard-height spindles built in, you'll get more clearance without having to raise your deck height.
There are many suspension options for your trailer or camper. So, what makes Timbren Axle-Less different?
Axle-Less systems are a definitive upgrade over traditional leaf springs, in part because they allow you to do away with your thru-axle, allowing for maximum clearance. As you've probably noticed, having a leaf spring suspension means that your axle will always hang at least a few inches below your trailer's frame, resulting in limited ground clearance. This may make it difficult to navigate rough roads.
In addition, while leaf springs do a great job of supporting an even load, they may cause your trailer to bounce and rattle when it's empty or to bottom out with a heavy load. And they don't offer any type of shock absorption for a smooth ride - unless you have upgrades built in. With Timbren's Axle-Less system, gone are the days of dealing with these annoyances - this suspension is designed for a quiet, balanced ride, whether your trailer's fully loaded or empty.
A torsion axle is a step up in terms of shock absorption, and it provides more clearance than a traditional, leaf spring suspension, but that crossbeam will still hang down some. And if your torsion axle gets damaged in any way, it can't be repaired - you'll have to replace the entire thing with a setup that matches your exact trailer frame width.
With the Axle-Less system from Timbren, you won't have a low-hanging axle beam to get in the way when you're driving on rough roads. The standard-height spindles on this setup will keep your deck height the same, so you'll get that extra clearance and still be able to easily load and unload your trailer. And the rubber springs and independent operation both combine to absorb shock and deliver a smooth, easy ride. In addition, the Axle-Less system can be easily maintained over time, and it will fit any trailer frame width, so you don't have to worry about potentially ordering the wrong size like you might with other systems.
Another suspension upgrade on the market is Timbren's Silent Ride. This setup is a great option to reduce bounce and rattle because it has the same AEON rubber springs as the Axle-Less system. But the Silent Ride still requires an axle, so you won't get the same ground clearance or low deck height as you will with the Axle-Less suspension.
The Timbren Axle-Less suspension is designed with you in mind. All of the parts work together so you can tow your trailer comfortably - regardless of load size.
The first step in installing the Timbren Axle-Less suspension is to make sure that the mounting points for each unit are directly across from each other. The easiest way to measure this is to mark the desired mounting points on your trailer's frame. Then measure the distance between these points and the center of your trailer coupler. These measurements (A and B) need to be within 1/8" to keep your trailer frame square.
Once you have your mounting points lined up, you'll be ready to install the system. Drill 3 holes into your trailer frame at the desired mounting points. Then bolt each unit to the frame with Grade 5, 1/2" bolts (not included).
Because Timbren's Axle-Less system eliminates your trailer's thru-axle, you'll have to find another way to get the crossbeam support that keeps your trailer frame square. You have a few different options to do this depending on your application and how much fabricating you're comfortable doing.
If you're building a trailer, the best option is to begin building with the Timbren Axle-Less in mind and include a crossmember where you want to install the units on your frame. You can also retrofit an existing trailer with a crossmember.
If you don't have a crossmember where you want to install the Axle-Less system (and you don't want to add one), pick up a section of 2" x 2" steel tubing from a nearby weld shop. This tubing will serve as a support to keep your trailer square. It will hang only about an inch down from your trailer frame, providing more clearance than a thru-axle.
After you've mounted both of the units to your frame, you'll need to drill 3 holes into the steel tubing and into the built-in, square holes. Then, insert the tubing through the holes and secure it with 3 bolts (not included) on each side.
The last option is to fabricate a reinforcement bracket that can be attached to the inside of your trailer frame and to the Axle-Less suspension. It may be a little harder to fabricate a compatible bracket than to mount steel tubing, but you may get additional clearance with this method.

Very smooth pull. I'm very impressed on how the trailer pulls. My traditional axle trailer seemed to bounce a lot on the highway which made a lot of noise, but with the Timbren Axle-less that I installed on a new trailer, the trailer is so smooth and way less noise.
Great product.
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.

Really cool work!
It is important to know that your wheels are going to sit very tight to the trailer frame. I needed to add an extension to the hub for it to clear the sides of the camper I built.

This suspension is rated for 2000 lbs, and my trailer weighs in at 1600 lbs. After about 30,000 miles though, elastic bumpers where basically flattened out. Good news is that these are super easy to replace, but bad news is that Ill be replacing the whole system with the 3600 lb system. Im guess that the bouncing on the suspension, even with a trailer that was under spec, exceeds the 2000 lb rating. So, the short story - these systems arent rated to the weight of your trailer, but the force of your trailers bouncing. Extra bad news - each of the Timbren systems are different sizes. The arm in this new one is longer, the distance of the hub from the suspension arm is greater, even the holes for mounting it are different spaces. So, it aint like you can just bolt on a different Timbren. Since the fenders on my camper are fixed, Ill be welding a plate over the existing drill holes and drilling new ones. I wish I had known before I purchased the first suspension system that the rating isnt about trailer weight. Still, the folks at etrailer have been super nice through the whole process.
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
So far great! I used one of the Timbren Axles in a mountain trail camp/SAR trailer I just finished building. I have only had the trailer on roads because all the trails I want to try it on are still under snow...but it is melting fast. I have included a couple of photos.
Needed a suspension system that I could make a low profile kayak trailer, that would fit in a specific area next to my garage. These were excellent that I could make the trailer any width I wanted. Easy to install and well made.
My only complaint is that I had to strip off the bad paint job, grind the sharp edges and apply real primer and paint. The factory paint was crap. I completed the build and have yet to load up the trailer to see what it can carry.
Just what I wanted and needed. 7,000 mile trouble free and exceptional traveling
Very easy to install, rides and tracks really good! I highly recommend these axles
Two of the holes need to be offset about a half inch from each other for bolts to fit proper. The middle hole on the side and the back Hole on the flat are in line with corresponding holes and hard to get bolts in both. Had to redrill the two.
Only axle I could find to fit my application. Very cool product. Fast delivery. Easy instructions
This is my favorite suspension system in all the world! Rides like an absolute dream. Easy to set up and install. Works on any trailer frame size.
One thing to know: You don't get the ride height you get with a standard leaf spring suspension. Even with 15-inch wheels, the ride height is pretty low - maybe 10-12 inches of ground clearance to the bottom of the main trailer frame. If you need more ride height, get the lifted version.
A few areas of possible improvement? It's difficult to bolt the suspension unit to a crossmember using the middle bolted hole, which uses a tacked-on weld nut. You have zero room for error when drilling the hole through your cross member, and you can't really use the suspension as a template.
Hmmm ... also, the hanger plate mounting holes are positioned 1-inch from the bottom of the trailer frame. That makes it very difficult, since I use channel side rails, to use standard 1/2-inch USS or SAE washers on the backside. There isn't room. Just an extra 1/4 of a inch would allow me to use standard washers underneath the nuts on a channel frame.
Nitpicking aside, it's amazing.
Installed these axels on Custum boat trailer to fit on top of our Jeep... worked perfectly
Thanks
etrailer does not provide sufficient information for a customer to correctly choose wheels / tires for this item, so while the suspension looks great and I'm looking forward to using it, I ended up with the wrong wheels/tires: specifically, this will NOT work with 14" zero offset rims (which is almost all of them). I got an RA on the wheels which guess what I can't use it because the only reason I know they don't work is I mounted them so I've wasted DAYS of my time with no progress on my trailer and STILL do not have a confirmed answer that if I buy X rim it will work with these despite writing to the person who helped me place the order days ago and no answer. This is really not what I expected I'm pretty wildly unhappy at being ignored.
not happy with one lug nut missing threads!!! but I think they also could supply the wedge plate! the horizontal holes never change and the lower vertical should be slots. for the money I shouldn't have to make a plate.
Very well made and love the ride compared to regular leaf spring axles.
The spring part seems weak. It has held up so far. Drove 3000 miles 1500 with a load of about 1200 lbs. Handles well on hiway but off road, like my gravel sandy clay road with wash boards, cattle guards and bumps, uneven terrain yet not serious off road altogether, the things are tipping at times and slowy becoming lower and less travel. Occasional the entire trailer bounces in air. These will need replacement before too much longer and seem a bit weak over all. Nice quiet sound and overall great but just not heavy enough to hold up off the smooth hiway
This is my first time in building something like this
Very well made ( thickness of steel, welding, overall construction, all the hardware for installation ) Installation very simple. Great product.
They worked perfect for my flat load motorcycle trailer. Been to Texas twice and Tennessee.
I think this is a great product, the holes on the sides could be a little bit higher, I had to double up the frame area for strength and the bolt holes were to low .
How can I discourage you from buying this product? Almost a $500 item, yet they can't supply you the 6 bolts to attach it to the frame. Get to the hub assembly, and another simple, but hard to find item a "tang washer" is not supplied. The 4 bolts to attach the square tubing is also not supplied, but expected that because they were very clear the tubing was not included. Of course, I expect this review will never be seen.
Always great help from e trailer helping me find what I need

Hands down better than axles. Much smoother ride and quieter. Ive had no worries or trouble with axle-less suspension for 1 year now. Thanks again Timbren
