Determining If Timbren Axle-Less Trailer Suspension Will Work With Brake And Wheel Assmeblies

Hi John,

Increasing the axle capacity will not increase the load that the trailer can haul because you're still limited to capacity of the trailer's frame. Swapping up to a higher weight class can also give you a stiffer ride and uneven tire wear because the suspension isn't being loaded enough to compress the suspension and have the tires sit straight without camber. There's also a lot of legal hoops to jump through when it comes to altering the GVWR of the trailer. If it's not a crazy capacity difference and you're not overloading the trailer then these issues won't really be as prominent.

All that being said, I do really like the Timbren Axle-Less suspension and can speak to just how much smoother the ride quality does feel with their built in jounce springs. Your 5-bolt brake assembly and ST225/75R15 tire size would be compatible with the # ASR5200S01. The hubs you might have to change out depending on your bearing and grease seals. The recommended bearing/seal combination for this system is as follows:

Inner # 25580 (Inner Diameter: 1.750")
Outer # 14125A (Inner Diameter: 1.250")
Seal # GS-2250DL (Inner diameter: 2.250")

If the inner diameters match up then you'll be able to reuse your old hubs.

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 3" 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.
