Looking for increased versatility for your utility, landscape, or construction trailer? Designing a trailer to have its deck drop down to the ground? Working on another type of light-fit custom or retrofit rig?

Our Axle-Less trailer suspension kits offer ultimate creative freedom for your custom trailer build.

With no through axle, there’s no need to worry about ordering the correct axle dimensions. Shims are also supplied giving you the flexibility to adjust, if necessary, the suspension alignment and camber specific to your trailer frame. And polyurethane bushings — used at the pivot point on the control arm — hold the pin firmly in place, resulting in better stability and a more controlled alignment with each moving component.

Axle-Less trailer suspension features two Aeon® rubber springs, one for jounce and one for rebound, absorbing road shocks and allowing for a quiet, smooth ride, whether on the highway or down a dirt road.

Durable and weather-resistant, these suspensions are built to last in any environment, from the heat of the Outback to the sub-freezing winters of Canada.

Each Axle-Less trailer suspension kit comes with both driver and passenger side to give you a full suspension.

Need something more suited for off-roading and overlanding? We recommend our HD series of Axle-Less trailer suspensions.

Weights and Dimensions

Choosing A Trailer Suspension

The optimal performance of an Axle-less system is achieved when the average load on the suspension falls within the range of 60 to 80 percent of its rated capacity. For example, a standard ASR35HDS Axle-less suspension with a load rating of 3500 lbs would operate most effectively with an average load between 2100 and 2800 lbs (950 to 1270 Kg).

It is important not to overlook scenarios of maximum load: In addition to the regular weight, consider all sources of extra weight: a full water tank, waste water tank, loaded fridge, generator and any other type of equipment, spare tire, one or two 12V batteries, water hose, power cord, and a propane tank, tent, ladder, tools, etc.

Keep in mind that the load distribution also plays a big role. In the case of a tandem trailer, due to a number of factors (including the height of the hitch, or distance between axles, etc) the load on the front axle could happen to be different that the rear axle. The weight on the left side could also be different from the right side. So one axle or even one corner could potentially be overloaded even if the trailer is not overloaded! Always follow safety guidelines and leave plenty of extra room for weight when choosing your suspension. This isn’t just about safety; it’s also about getting the best ride quality and handling for your trailer.

If you need further assistance in selecting a suspension for your trailer. Please reach out to Timbren’s Customer Service Team.

 

*Please note that these are the maximum allowable tire sizes for each suspension, not necessarily the most popular or preferred ones for your trailer application. The assumption is that you are using a standard trailer wheel with zero offset.

Each Axle-Less trailer suspension kit comes with both driver and passenger side to give you a full suspension.

Axle-Less trailer suspensions are fully independent and do not require an axle, allowing for ultimate control of your rig.

A torsion trailer suspension, on the other hand, is housed within an axle tube and isn’t designed to hold up to the abuse and rigors of off-road or overland travel.

Our jounce and rebound springs are made from natural rubber, with all the unique characteristics that make our Aeon® springs a leader in towing and hauling.

The capacity rating represents one complete Axle-Less trailer suspension (i.e. both sides).

Yes. Some maintenance is required, such as greasing the pivot bushings and wheel bearings.

For detailed maintenance information, refer to the maintenance notes included with the installation instructions.

To begin, you’ll need to make sure the frame is perfectly square. Additionally, some trailer frames require additional support, like an extension plate to allow bolts to be installed vertically. This would eliminate the use of a cross-member, allowing you to achieve maximum ground clearance.
