Is There Similar Product To Timbren Axless-Less Suspension Compatible With A Triple Axle Setup

Question:

Hi Kevin, thanks for coming back to me. My idea is to build a 8000lb caravan using tyre-axle instead of twin. The reason is that each axle is then lower rated and therefore has a softer ride and the caravan is much more stable on the road and much less likely to snake. An independent suspension is much nicer to the chassis and allows a much softer ride. If Timbren does not allow to use their suspension as tri-axle setup, is there a similar suspension out please? with kindest regards

Axles are there to support the weight of the trailer so increasing the number of axles would not result in a softer ride quality like you're thinking. The suspension, whether it's leaf springs or Timbrens, would be the determining factor in ride quality. There isn't a similar product out there to match Timbren's axle-less suspension that could be used in a triple axle setup.

A Timbren Axle-less suspension like # ASR2KHDS03 would be a great option if you were going off-road since leaf springs typically can't handle the bouncing from a rough terrain and could potentially crack, snap, or flatten out. This is why SuperSprings International and Timbren made bumpstocks for leaf spring suspensions to help cushion and support the loads on a trailer. Leaf spring suspensions along with suspension enhancements tend to be quite a bit cheaper than the a Timbren axle-less suspension as well.

Triple axle trailers can still experience sway depending on how you load the trailer. Too much or too little tongue weight can vastly change how the trailer tracks behind the tow vehicle. Independent suspension could actually cause more stress to the frame of the trailer since it's directly mounted to it and puts more pressure on the chassis that a typical axle/leaf spring setup. If you read the fine print for one of these systems they tell you install supports between the frame beams where these are installed to prevent them from potentially bending the frame.

If you don't plan on taking the trailer off-road over rough terrain then I recommend using an axle and leaf spring suspension and picking up some suspension enhancement like the # TSS-106-40 (fitment depends on the axle capacity and leaf spring orientation) to help soften the ride quality.
