3500 lb Axle-Less Trailer Suspension w/ 4” Lift
The 3500 series Axle-Less trailer suspension is not only durable but also provides a ride that’s so smooth you’ll forget you’re pulling a trailer. And because there’s no thru axle, you never need to worry about ordering the correct axle dimensions!
This 3500 lb Axle-less trailer suspension comes with outboard arms equipped with 4” lift and our standard length spindles for use with standard-width tires 225/75R15 or smaller. A brake flange is included for optional use with brakes.
If you’re planning to take your trailer off-road and/or use tires bigger than 225/75R15, we recommend you choose the 3500 lb HD line of suspensions here.
Due to higher than anticipated volumes we're currently experiencing a 4 to 6 week lead time.
The genius of the Axle-Less trailer suspension has more to do with what is not there than what is:
- Less hassle! Experience fewer limitations by gaining more ground clearance.
- Less time! You can retrofit any light-duty trailer without waiting for an axle that fits.
- Less road shock! You will maintain the smoothest ride with or without a load.
- Less danger! An independent suspension gives you better control of your trailer.
The Axle-Less suspension gives you more creative freedom. Now you have more options to design and build your trailer.
Shims are also supplied giving you the option to adjust, if necessary, the suspension camber specific to your trailer frame.
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. They are weather-resistant and made to last longer, especially in a harsh environment.

Does it come as a pair or just one side?
When you purchase one Axle-Less trailer suspension, you always get enough for both sides of the trailer. The price you see advertised includes both left side and right side.
Is the capacity rating for Axle-Less suspensions for one side or both?
The capacity rating represents one complete Axle-Less suspension, i.e. both sides.
Why are some Axle-Less suspensions marked ‘HD’?
The “HD” in an Axle-Less part number stands for heavy-duty. The HD versions are more robust compared to their regular-duty counterparts with the same nominal load rating. For example, ASR2000S and ASR2KHD both have the same load rating (2000 lbs) even though the first one is regular-duty and the second one is heavy-duty. HD suspensions are constructed using thicker steel making them much stronger. Therefore, they withstand more abuse, harsher conditions, and more dynamic loads. HD suspensions are recommended for off-road applications.
Do I need to do anything special to my trailer frame to use the Axle-Less suspension?
First of all, you need to make sure the frame is perfectly square. Secondly, 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.
Does the Axle-Less trailer suspension require any maintenance?
Yes. Some maintenance is required for the Axle-Less suspension such as greasing the pivot bushings and wheel bearings. For detailed maintenance information, refer to the maintenance notes included with the installation instructions.
What kind of warranty comes with the Axle-Less trailer suspension?
The Axle-Less trailer suspension comes with a full 3-year limited warranty.
What’s the difference between an Axle-Less suspension and a torsion suspension?
Axle-Less trailer suspensions are fully independent and do not require an axle. A torsion trailer suspension, on the other hand, is housed within an axle tube.
What are Axle-Less trailer suspension springs made from?
Axle-Less jounce and rebound springs are made from natural rubber, with all the unique characteristics inherent in rubber springs.
