Recommended Suspension Enhancement for a Tandem Axle Trailer With 3.5K Overslung Axles

Published 07/13/2023

Question:

Hello, I have a tandem axle travel trailer with 3500lb electric break lippert axles. The frame width is 71 from edge to edge with Overslung mount. I would like to upgrade to larger weight capacity axles along with leaf springs and wheels. Could you help me with getting the correct parts together and pricing. Thank you for your time.

You could upgrade your axles to a higher capacity, however it isn't really recommended since it can create a rougher ride.

Since you've got 3,500 lb axles I'd stick with those and upgrade your suspension with the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # TSS-107-40.

These springs are going to help improve handling while providing additional support for an overall more smooth and comfortable ride.

Also, since you're looking for new leaf springs, I am going to need you to measure from eye to eye on your current springs and let me know what that is so I can find you the correct springs.

Same deal with your wheels, let me know what you have and I'd be happy to shoot you a couple of recommendations. There are a couple of help article I've attached for you to check out that will walk you through how you can measure your wheels.
