Progressive Cushioning That Travels with Your Load
Trailer SumoSprings are built from the same microcellular polyurethane that powers the entire SumoSprings line. Once mounted directly onto the trailer’s leaf-spring pack, they compress progressively as the trailer is loaded — cushioning bounce, minimizing sway, and reducing stress on trailer components. There are no moving parts, no hoses, and no adjustments required. Whether you’re hauling gear, equipment, or family toys, they automatically engage under load and stay quiet and effective for the long haul.

For Campers, Contractors, and Every Load In Between
Trailer SumoSprings are ideal for utility trailers, cargo haulers, toy haulers, and travel trailers with 1.75" leaf springs. They’re perfect for anyone looking to reduce trailer bounce, minimize sway, and protect the cargo inside — whether that’s gear, equipment, or your weekend setup. For heavier-duty needs, HD Trailer SumoSprings offer even greater support and shock absorption for trailers with wider springs and higher axle capacities. No matter the application, Trailer SumoSprings improve safety, extend component life, and deliver a smoother towing experience from the moment you hit the road.
Find the Right Trailer SumoSprings
Two applications. Enough to cover just about every trailer out there.
Trailer SumoSprings are manufactured from our micro-cellular polyurethane. Designed to remove sway, hop, & vibration, this zero-maintenance airbag alternative increases overall driver control and ride comfort when towing. If your towable has axles with a weight rating of 5,000lb or greater, you’ll need the black (-47) option. This will you give you the best load support and control.
