Converting a Single Axle Trailer To a Tandem Axle Trailer With Timbren Axle-Less Trailer Suspension

Question:

Could these be used to convert a single axle to tandem, by simply adding them to an existing spring set up?

I would not recommend adding the Timbren Heavy-Duty Axle-Less Trailer Suspension # TASR35HDS11 behind or in front of your existing axle to transform your single axle trailer into a tandem.

First the single axle that you currently have will likely have a different deflection distance than the Timbren which could lead to parts being damaged easier.

Second the weight would most likely not be balanced properly across the trailer and axles. As it sits your single axle is at the load point that allows for the proper amount of tongue weight to sit on your trailer. By adding a axle in front of or behind the current axle it will change the load distribution of your trailer.

You should really match your suspension so that you have the same deflection and space the axles evenly where the weight is properly distributed. I have linked one of our articles below that will help you with axle placement.
