If your 2021 Jayco Jay Flight 28BHS Travel Trailer has 3K to 5K axles that are over-slung springs, use SumoSprings, # TSS-107-40. For tandem axle applications, use 2 kits.

The SumoSprings Trailer Helper Springs will improve suspension, handling and safety using a progressive spring rate. These become more rigid as greater weight is added and works independently side-to-side. So this helps to reduce body roll as well when turning corners.

Over-slung leaf springs sit on top of the axle, they are “over” the axle. While underslung mounting has the springs attach below the axle.
