Getting hung up on rough roads or steep driveways is no fun. This axle-less suspension eliminates the traditional thru-axle so nothing hangs below the frame. The standard-height spindle keeps your deck height the same while giving more ground clearance from front to back. Each side bolts directly to the trailer frame, so it fits any width and keeps things simple for custom builds or smaller trailers.
Bumpy roads no longer mean a rattling, jarring ride. The jounce springs made of AEON heavy-duty hollow rubber absorb road shock and support the trailer’s load, while rebound springs control movement to minimize sway, bounce, and bottoming out. The result is a smoother, quieter ride whether the trailer is loaded or empty.
Each suspension unit works on its own, so what happens on one side doesn’t affect the other. That keeps the tires planted and stable through turns or uneven pavement. Built-in camber and toe-in help the tires track true and reduce wear over time, keeping handling controlled and predictable.
This setup includes idler hubs with a 4 on 4" bolt pattern and E-Z Lube spindles for quick grease service. Inner and outer bearings (L44649), races (L44610), and seals (10-9) are included for a complete, matched assembly. The 1,200 lb weight capacity covers both sides together, perfect for light-duty builds. A black powder-coat finish protects the strong steel construction from rust, so it stays solid and dependable for many miles.

I've never used these before but were perfect for our situation.
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
I love the way this product performs. Installation was very easy but I do need to shim one side to get the one wheel to track better.
A little pricey but we will see. Could have provided a plate for the inside ended up spending another $200 for angle iron and bolts to install
Had a broken torsion axle on dual axle boat trailer. Manufacter six to eight weeks to replace. Got this product in week. Installed same day. Very happy .cancelled new Axel order.
I used these parts to build a motorcycle trailer. (See attached pictures) It pulls and handles like a dream. The Atwood coupler and the Timbren axle-less suspension are both very well designed and of high quality manufacture. I would recommend these parts to anyone.
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.
pretty awesome
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.
enclosed are pics of trailer and spindle units. I was very happy with the end result,
lowering ez loader trailer 8 inches for hovercraft. the spindle units were well made,
very strong but had some weld repairs as pictures show.i could not set the needed
adjustments till I cleaned up the units with a stone and file. also please improve the
packaging . these heavy units need something better than cardboard for shipping.
they were dislodged from Styrofoam and partially poked holes thru cardboard. but
fortunately no damage there. again im happy with the installation.thank you!!!
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.
I rebuilt a 4 x 8 trailer using the Timbren Axle-Less Trailer Leaf Spring Suspension and it works great. I would recommend it to others.
The customer service has been "top-notch" . . . very pleased!
Shipped fast. Parts look good.
Customer service was excellent! Thanks!
This is a quality product that will work well for its intended purpose. I was seeking something with a significantly lower weight load range, so these turned out to be too stiff for my needs. However, I will keep them in my shop and they will eventually be used to construct a trailer that NEEDS 1,200 lb. of load capacity.
The axle-less suspension worked very well for my boat trailer. The suspension was easy to attach to the trailer frame and provided a lower profile than the traditional leaf spring and axle system.

After a year of use, still working well. The trailer tows well and the lower profile is helpful when launching.
