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.

  • Solution for Replacement Hub For 2k Axle With LM48548 Inner Bearing
    The 1.375" measurement corresponds with the # LM48548. The closest thing to 1.255 I'm aware of is the # LM67048 which measures 1.250" for the inner diameter. One way or another, bearing combinations using the # LM48548 are obsolete so we do not have a hub that will fit. The best solution is to replace the axle with one that uses a modern bearing combination. To find a replacement axle you will need the hub face to hub face measurement. I have attached a helpful video below which explains...

  • Availability of Replacement Hub for AL-KO 8440
    Hi Kevin; I agree and would say that the # AKHD-545-2-EZ-2K will give you the same result. Unfortunately, this seems to be a classic case of AL-KO parts not matching industry standards. AL-KO is no longer around, and many of their axles/spindles/hubs didn't match up with other brands. You might be able to find some old AL-KO parts out there but we don't carry them anymore. The best solution I can offer is complete axle replacement. Since none of our 2k axles have a brake flange the universal...

  • Best Trailer Axles To Use For A Spring Center To Spring Center Measurement Of 74"
    I do have trailer axles similar to what you are looking for in our Timbren Axle-Less Suspension Systems however, we do not offer torsion axles at this time. In order to recommend a proper replacement axle for your setup, I would need to know the weight capacity of the axle you are seeking. For a Timbren Axle-Less Suspension System, you would use part # ASR2000S02 for 2,000 lb. axles, part # ASR3500S05 for 3,500 lb. axles, or part # ASR5200S01 for 5,200 lb. axles.

    The most I was able to find about the Coleman 4735CC201 leaf spring is that it's rated for 1,000 lbs which means it goes to a 2,000 lb axle.

    Hi Gerald; I wasn't able to find anything that corresponds with that axle part number through Karavan.

    There are Timbren axle-less suspension systems that do not come with hubs so that you could add your own such as # AKIHUB-550-35-EZ-K. But the hubs with 5 on 5 bolt patterns that would also fit a Timbren system only accept up to 15 inch wheels.
