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.

Timbren Axle-Less Suspension vs. Other Suspension Systems

There are many suspension options for your trailer or camper. So, what makes Timbren Axle-Less different?

Leaf Spring Example

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.

Torsion Axle Example

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.

Timbren Silent Ride Example

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.

Timbren Axle-Less Suspension Parts

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.

Timbren Axle-Less Suspension Parts Diagram

  1. The jounce spring supports the weight of your trailer and cargo. It easily absorbs road shock and is constructed of AEON heavy-duty, hollow rubber.
  2. The rebound spring delivers a smooth, stable ride - regardless of how much cargo is on the trailer. It controls the movement of the jounce spring to minimize trailer body roll, bounce, rattle, and bottoming out.
  3. The trailing arm with integrated hanger attaches 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 polyurethane bushings that never require lubrication.
  5. The E-Z Lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money compared to a traditional axle.
  6. The built-in hole accepts 2" x 2" steel tubing (not included) to add support to your trailer's frame. The tubing sits higher than a trailer axle, providing additional ground clearance.

Installing the Timbren Axle-Less Suspension

Measuring Diagram

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).

Keep Your Trailer Frame Square

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.

Crossmember Installation

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.

Steel Tubing Installation

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.

Reinforcement Bracket Installation

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.

Average Customer Rating:  4.6 out of 5 stars   (302 Customer Reviews)

Get more clearance and a smoother ride. Built-in shock absorption limits rattle and bottoming out. E-Z Lube, standard-height spindle keeps your deck height the same. Fits any trailer frame width. Includes inner (L44649) and outer (L44649) bearings.


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.


Customer service was excellent! Thanks!


Shipped fast. Parts look good.


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.


The service from etrailer has been great! They have been very helpful through the entire purchasing process. My one star is due to the quality of the product. First, for something as heavy duty as these are, you’d expect better packaging. On arrival, one of the spindles was sticking out of the box and the hand holds were torn on one of the other boxes. I was a little worried what I might find in the damaged box but everything seems to be intact. The disappointing part is the quality of the welds. For the price you are spending on these, I would expect a higher quality of fabrication. There is undercut in the welds that hold the three support plates together and big ol sloppy welds every where else. Unsure of what to do as my trailer has been designed around this suspension system.


I purchased the 3500 lb. set w/4" drop. Wish they made a 2" drop. Install was fairly easy, but most of your time will be consumed with alignment measurements, acquiring shims, and making adjustments. I was lucky to have a very square trailer frame. However, the "slop" in the all of the mounting bolts (especially, the spindle mounts) is more than the 1/8" window they specify. You will want to preload all bolts before tightening, and then measure for alignment/toe-in. The units are supposed to have camber built-in, but it's not near enough (more shims). Also, this suspension has more travel then the documents indicated. I had to re-mount my fenders 1" higher to keep the tires front hitting. When fully loaded, you might have 1" of travel left. All that being said, the ride is better than I anticipated. It's less bouncy than a torsion axle, and very quiet. If I was building a trailer from scratch, I would use this system, again.


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.


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.


We made an amazing creation out of those two axle-less axles.
We made a large fuel cell that is used for offroad use and it has worked excellent this entire time.
They are really great products and we would love to work with them again.
Actually, we do a ton of social media stuff and youtube and if you ever have interest in sending us products to build content around, I would love to have the opportunity!

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!


Trailer suspension and disk brake performance is outstanding big big difference over leaf spring and electric drum brakes.
Installation required modifications to the frame to monut the timbren suspension


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.


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.


Installed the Timbren Axle-less suspension a little over a year ago and approximately 5000 miles ago. I have been extremely satisfied with the installation and performance thus far and have had no issues. I also chose to install an optional crossmember for more strength using a 1/4" thick piece of 2x3 steel. I had to increase the weight capacity of my campers suspension due to renovating the interior completely and adding more weight. I also strengthened the frame to accommodate the extra weight. In addition to installing the Timbren 5200LB system I installed new 12" electric brakes and upgraded to 225/75R15 tires with E load range rating.

They have more pros than cons, but the second set I bought broke the flat plate that holds the spindle at about 8 months. The steel quality seemed less than I would expect since it basically peeled it back like a pop can as you can see in the pictures. Otherwise I like the clearance and ride. They last 2-3 years where the torsion axles I replaced would wear out in 4 months after driving down rough gravel roads. There is a grade zerk on the underside which I didn't realize until I bought the second set. That would have helped the first set last longer had I known about it.


Incredible system. Handled our Overland trek through Colorado and Moab. These axles on our 1917 Ford bed ran multiple Jeep Badge of Honor trails. The suspension handled flawlessly. Handles off camber rocks and drop offs smoothly. We ran the 4 inch lift and off road offset to fit the factory Jeep wheels.


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.


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!!!


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.


I put these on an off-road trailer build. They have been fantastic! I've done many miles and they held up great. Highly recommend.


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


The order came in on time and the customer service at (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.


Five star. shipping was slow. Product was great 14 K 14 plies under 2000 pounds independent suspension. Low fast and sassy. Yep that’s how I build them.

  • Replacement Axle and Suspension System For a Small Boat Trailer With 55" Wide Axle

    I called my contact at Timbren to get some information for you about the axle-less systems. For the 1,200-lb systems the distance from the center of the spindle to the underside of the frame where the bracket mounts it is 2-5/8 inches. And for these systems they have a deflection of 2-1/8 inches. I have attached a drawing that shows these dimensions you can check out. You will want at least an inch over the deflection distance.

You won't find 14" or 15" wheels that can use a 4 on 4 bolt pattern so you're definitely going to need a hub with a 5 on 4-1/2 bolt pattern like this one.

  • How Much Distance Should I Have Between The Tire And The Trailer Frame?
    I can certainly point you in the right direction. I will start by saying that our "rule of thumb" is that we want at least 1" of clearance between the tire and the trailer frame. With the hub face currently at 48", you will want to go with an axle that is at least 50" hub face, if not a bit longer. 54" would be acceptable, but we would not want to go longer than that.   Unfortunately, we do not offer any axles that will be close to this size. Our shortest round tube axle is 60" hub face....

  • Choosing The Right Replacement Boat Trailer Axle
    One thing to note, when picking the right trailer axle there can be a bit larger of a measurement when taking the Hub Face to Hub Face measurement, but the spring center to spring center measurement needs to be spot on. That being said, you could use this axle # 20440I-ST-60 or this axle # 20440I-EZ-60 which are both 60 inches long. So depending on what the offset of your wheels are, you may have them sticking out a bit farther than usual. The distance between the spring centers however,...

    I have a set-up that may work for you, but unfortunately we do not have exact matches for the parts you are looking for.

This will replace your leaf spring suspension and give you the 4-on-4 idler hubs. It will bolt directly to your trailer frame and give you greater ground clearance because...

  • Parts Needed To Add Idler Hubs To a Log Splitter Trailer Which Uses a Wheelbarrow Style Wheel
    Adding a system like the Timbren Axle-Less Trailer Suspension System # A12RS440 will allow you to bolt to your frame on your log splitter trailer. This will give you an idler hub and suspension to give the log splitter a smoother ride on the roads. The hubs will accept a 4 on 4" wheel and tire like the # AM30630. Otherwise you can get 2 Spindles # TRU44FR to weld onto your trailer in place of the wheelbarrow type axle. Then you will be able to add 2 Hubs # AKIHUB-440-2-G-EZ-2K which also...

  • Recommended ATV Trailer Axle and Wheels
    There are no trailer hubs that are compatible with your ATV Rims. Your ATV bolt pattern equates to 4 on 4-1/3 inches which is not a trailer hub option. For your off-road ATV trailer, I recommend the Timbren Axle-Less Trailer Suspension System with Hubs -1,200 lbs # A12RS440. These do come with the EZ-Lube spindles for easy maintenance. Then for your tires and wheels I recommend the Kenda 205/65-10 Bias Trailer Tire with 10" White Wheel - 4 on 4 - Load Range C # AM3H370. I've attached...

  • Axle Kit for Fabricated Ice House Trailer
    All of our trailer spindles are shown on the linked page, but none of these has a stub end to fit 2 x 3-inch tubing. All are either round like # TRU74FR or square like # TRU47FR. For a fabrication project like yours a better solution may be a bolt-on axle-less suspension kit from Timbren, such as # A12RS440, which is rated for 1200-lbs and which includes idler hubs with the 4-on-4-inch bolt pattern. Bearings, races and seals are included with hub. All Timbren axle-less kits and beam axle...

  • Axle Recommendation for Small Camper Trailer Towed Behind Motorcycle
    You'd be a good candidate for the Timbren kit part # A12RS440 which is an axle-"less" kit that attaches to the trailer frame directly. I attached a picture that shows how it attaches to a trailer frame. It wouldn't require you to measure out the exact axle length you need either. The capacity is 1,200 lbs.

  • Recommended Trailer Axle For Haul Master 4x8 Foot Trailer
    Replacing your existing axle with the Dexter Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 60" Long - 2,000 lbs # 20545I-ST-60-15 or Dexter Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern - 60" Long - 2,000 lbs # 20440I-ST-60 will work fine as long as the Hub-face-to-hub-face length is 60 inches and spring-center-to-spring-center length is 48 inches.

  • Axle Recommendations for Homemade Motorcycle Trailer
    I can help you determine which Timbren Axle-less system is the right one for your trailer. If your total trailer weight including the weight of the motorcycle is under 400lbs. then the Timbren # A4WS440 system will be a good fit for you. These axle-less systems provide a smooth and quiet ride without having to sacrifice any ground clearance. Depending on what your total trailer weight ends up being you may want to go up to the next highest capacity set rated at 1,200lbs. # A12RS440. If...

  • Timbren Axle Less System Recommendation with a 5 on 5 inch Bolt Pattern Hub
    If you were to get the Timbren Axle-Less Trailer Suspension System # ASR2KHDS02 you would get almost the same system as the part # A12RS440 that you referenced minus the hubs, but also a 2,000 lb capacity. You would be able to pick a different hub to fit the spindle. The correct hub you would want that would also give you a 5 on 5 inch bolt pattern would be the Trailer Hub Assembly # 84550UC1-EZ. In the 1,200 lb capacity range there is no way to get the bolt pattern you want.

  • Replacement Hubs for Oddball Axle or Axle Replacement for Boat Trailer
    The Trailer Hub Assembly - 3,000 lbs Axles - 4 on 5 - Agricultural # AH15450ECOMP is the only fit we have for those bearings. It has an odd bolt pattern of 4 on 5 inch. This likely isn't what you are seeking for your boat trailer. If you can give me some more information on your trailer I can help with a replacement. For a standard trailer axle, I need to know your spring seat to spring seat measurement, bolt pattern of your hubs, and measurement from hub face to hub face. If your measurements...
