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 steel tubing to connect the 2 Timbren suspensions together using the built-in square hole on each unit.
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 holes make it easy to reinforce your trailer's frame by adding standard, 2-inch-square 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.
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'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.
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.
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-square 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).
The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.
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.
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).

Very easy to install, rides and tracks really good! I highly recommend these axles
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.
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.
Sierra K - 07/07/2021It 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.
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.
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.
R C - 12/19/2021Only reason it's 4 stars instead of 5 is because the axle shafts both has weld spatter on them. Unnoticed this would have destroyed the inner seals.
Installed these axels on Custum boat trailer to fit on top of our Jeep... worked perfectly
Thanks
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.
Only axle I could find to fit my application. Very cool product. Fast delivery. Easy instructions
Well I thought it would be delivered like the picture
Totally unassemblef
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.
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.
I wanted to give a lot star, but I spent three months because you missed parts of me a few times.
Anyway it is very good for the product.
Delivery was on time, product is great the only thing the main box was open and broken thanks to the product being large and did not fall out of the box Thank you Benny
Put these on our teardrop camper about a year ago and have about 3000 miles on them. Smooth and quiet and awesome ground clearance. Would definitely recommend these over a conventional axel.
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.
I pull my Sea Doo GTX 300 (that means they are pretty heavy!) PWC's from Wisconsin to Florida twice a year. That said, this last trip to Florida caused me to bend the original straight axle on my trailer. Not fun. I ordered the Timbress Axle -less axles, and after a few hours of work on the trailer, they were installed, square and true. I immediately put the Sea Doos on the trailer to see how the trailer performs with the new axle-less system on it. one word: FANTASTIC!!!! I guarantee if I have to fix this issue again, I will use the exact same product. It is awesome!
This is my first time in building something like this
This was delivered much later than promised when ordered. It arrived in a damaged package and hardware was missing.
Brooke M - 08/31/2021The product was in perfect condition when it arrived. Please extend a sincere "Thank You" to who ever prepared my order for shipment. The axle systems are heavy and bulky but were superbly packaged. Not even a scratch. all the parts arrived with nothing missing. There was even nice bunch of shims. No one ever sends enough shims. If they are needed I won't have to stop and get more. Very good workmanship on all axle parts and assemblies. The only problem I had was communication with you. I received no info from you about my order after the initial automatic one when I placed the order on the web site. A long time went by and nothing. No updates, confirmation, explanations, nothing. I had to use the "contact" email on your web site. That took a day or so. You folks were very polite and professional, thank you, but during these times it's hard to know if things working as expected. Keep in touch. Thanks. I haven't used the axles yet. Sorry no pictures.
I used this to beef up a foldable trailer that had a cheap suspension and tires. It worked great!
