Do You Have an Axle that Will Have a Good Ride Quality for a 300-500 Pound Load?  

Updated 12/16/2024 | Published 12/05/2024

Question:

I am looking for a narrow wheelbase suspension for a lightweight utility trailer. I looked at the ASR2KHDS01 suspension, which would be ideal EXCEPT that it seems to be unavailable for load ranges of 300 - 500 pounds. Can this suspension systems capacity be lowered to this level? Do you offer any alternative? I did purchase independent swing arm suspension from Amazon, but the overall hub-to-hub width is too wide for my application. I do not want to use leaf springs, so I am seeking some independent suspension alternative. If the rubber compression pads could be reduced in strength somehow, that would accomplish my goal.

Hello Joseph,

Timbren actually makes an axleless suspension rated for 1,200 pounds # ASR1200S04, but the optimal performance would be when it is loaded at 60-80% so 720-960 pounds. When you are rated too high for your 300-500 pound load it can cause a stiffer ride and will have less effective shock absorption. Since you are looking to not use leaf springs I recommend that you look for a torsion axle. We unfortunately do not carry torsion axles, I know that our friends at Dexter make one that should work for your application. I would give them a call.

Hi Kate, Thank you for your reply. Yes, I have looked at the torsion axles. unfortunately, the axle I need beneath a touring motorcycle's pod trailer is VERY narrow, perhaps as little as 28 INCHES total width, and no one makes a torsion axle that narrow. I know that I can buy one and cut it to modify it, and that is still an option. In a world where people find it difficult to think OUTSIDE of the box, suspension designers and manufacturers cannot grasp the concept of an ideal suspension system for a small trailer that may not exceed 300 pounds of total weight, INCLUDING the trailer itself. They tell me to use a SOLID axle mounted to the frame. However, if you have ever towed a solid axle trailer behind a motorcycle, you would quickly understand how the lack of ANY suspension creates a serious handling issue for the rider. I will continue my search for the ideal suspension, or I will end up manufacturing it myself. Joe

@JoeJ Hello Joe. I spoke to one of my co-workers that has a little more experience with the Timbrens than I do. I told him how much weight you would be hauling, he stated that the # ASR1200S04 will work just fine for you. He said you can't notice the difference in what Timbren has listed for their optimum ride quality. I have not pulled a trailer behind a motorcycle, I would imagine you would feel every bump in the road and it would definitely require some skill.
