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.

From washboard roads to salty slush

Engineered to Endure Road Abuse and Weather Extremes

Built for Tough Roads. Made for Tougher Hauls.
Constructed from closed-cell microcellular polyurethane, Trailer SumoSprings are naturally resistant to corrosion, chemicals, moisture, and extreme temperatures. Their foam structure compresses and rebounds thousands of times without fatigue, delivering consistent performance even under punishing conditions. Backed by our lifetime warranty and trusted by OEMs, they’re the upgrade that doesn’t wear out — even when the road does.

Support that doesn’t leak, sag, or demand constant attention.

Better Than Airbags. Smarter Than Steel Brackets.

Airbag systems can be powerful — but they come with a cost: airlines, compressors, and constant maintenance. Steel reinforcements and helper brackets add complexity but don’t absorb shock. Trailer SumoSprings deliver a better solution: progressive load support that activates when needed, softens harsh hits, and protects your trailer without the need for attention or adjustment. The result is quieter towing, better handling, and longer-lasting trailer components — with a quick bolt-on install.

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

Deux applications. Suffisamment pour couvrir à peu près toutes les bandes-annonces.

Les SumoSprings pour remorques sont fabriqués à partir de notre polyuréthane microcellulaire. Conçus pour éliminer le roulis, les secousses et les vibrations, cette alternative aux coussins gonflables ne nécessitant aucun entretien augmente le contrôle du conducteur et le confort de conduite lors du remorquage. Si votre remorque possède des essieux dont la capacité de charge est de 5 000 lb ou plus, vous aurez besoin de l'option noire (-47). Cela vous donnera le meilleur soutien de charge et le meilleur contrôle.
