Helpful Expert Reply:

For a trailer with underslung axles(leaf spring mounted below the axle) you will need the SumoSprings Trailer Helper Springs in either a 3,000-5,000LB Capacity # TSS-106-40 or 5,000-8,000LB Capacity # SS33HR. The weight capacity of the springs will need to match your single axle capacity. You will want a set for each of your axles if you have a tandem or triple axle trailer.
