Rough pavement doesn’t have to rattle your cargo or your nerves. This Timbren Axle-Less Trailer Suspension uses AEON rubber jounce and rebound springs to take the hit from bumps and potholes. The setup absorbs road shock, minimizes bounce, and keeps the trailer stable whether it’s loaded or empty. With 2-7/16" of suspension travel and 1-3/4" of deflection under load, it rides smooth and quiet mile after mile.
Dragging a low axle over ruts or driveways gets old fast. This system eliminates the thru-axle completely, boosting ground clearance while keeping the same deck height. Each of the two independent suspension units bolts directly to the trailer frame, so what happens on one side doesn’t affect the other. You get a stable, balanced ride and the extra room underneath to clear rough terrain or protect plumbing and wiring.
Finding the right axle width can be a guessing game—but not with this one. The Timbren Axle-Less design fits any trailer frame width and can be bolted or welded in place. The strong steel housing takes hard use, and the black powder coat fights rust and corrosion. If your frame doesn’t have a crossmember where the units mount, the built-in square holes accept a 2" x 2" steel tube for added support and frame stiffness.
Regular grease service keeps any trailer rolling smooth. This system includes standard-height E-Z Lube spindles and idler hubs pre-fit with inner and outer bearings (L44649), races (L44610), and seals (10-9). Grease zerks on the spindles make bearing maintenance simple, so you spend less time under the trailer and more time towing with confidence.

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
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
The suspension works as it should….but be careful buying from etailer. When we got ready to install these several months later, the hubs were not in the box. I had to buy two hubs because of etrailer’s return/missing item policy. I just bought two more sets of these and everything else needs to build to more trailers from a supplier because of this.
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.
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.
Just what I wanted and needed. 7,000 mile trouble free and exceptional traveling
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.
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.
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.
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.

good
The suspension is solid and bulletproof. I'm very happy with my purchase and recommend it. I also appreciate that the manufacturer reached out for this review after 1 year and I'm happy to respond. Great customer service.
I've never used these before but were perfect for our situation.

Looks awesome, John! Not to look completely ignorant, but what is it that youre towing there?
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
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.
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.
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
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.
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.

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
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.
