Long trips and uneven roads can make a trailer bounce and jolt. This 2-leaf slipper spring flexes under load to absorb road shock, keeping the ride smooth and steady. It acts as part of the suspension system for a 1,800-lb axle, helping reduce wear and tear on the trailer and keeping things level even on bumpy surfaces.
Each spring carries up to 900 lbs, working together to handle an axle capacity of 1,800 lbs. With sturdy steel construction and a 3/8" leaf thickness, it’s built to manage regular hauling without sagging or losing shape. It gives dependable support mile after mile, whether you’re on pavement or rougher roads.
Getting the fit right matters for proper suspension movement. This spring measures 30" from the center of the eye to the end, with a 1-3/4" width that matches standard hangers. The front eye includes a 9/16" nylon bushing for smooth rotation on the suspension bolt, while the flat slipper end slides cleanly into the rear hanger or equalizer for a solid connection.
Whether you’re swapping out worn springs or building a new setup, this design makes it straightforward. It fits hangers that are either pre-mounted or part of an aftermarket kit (sold separately). Replacing both springs at once ensures even alignment and consistent performance, keeping your suspension geometry right where it should be.

No problems, upgraded PWC trailer because the new PWC is heavier 4 stroke. With springs and larger tires, it allowed us to not need to purchase a new trailer.

Good luck on the re-build, Tim! How much more do you have left to do?
