Improve your towing experience with this shock absorbing upgrade kit for leaf spring trailer suspensions. Heavy-duty shocks reduce trailer bounce, chucking, and porpoising. Adjustable mounting brackets and hardware included. Fits 3-1/2" axles. Heavy-duty gas shocks absorb road vibration to provide a more comfortable towing experience.
