Trailers

Most trailer suspensions are built for a single weight range — not the constant load, terrain, and road changes fleets face daily. Over time, that leads to sway, bounce, and uneven tire wear, causing costly downtime. SuperSprings International solves this with trailer suspension systems engineered to absorb shock, stabilize sway, and maintain ride height under shifting payloads — keeping trailers level, controlled, and on the road longer.

A Smoother Tow, Without the Complications
--

Everything your trailers need for safer handling, longer life, and zero
maintenance — without the hassle.

Less Sway, More Stability

Reduce side-to-side sway and bounce from uneven loads or rough roads for safer, smoother, and more controlled towing.

Stays Level Under Load

Maintain steady ride height and control at any load level, minimizing tire wear and improving braking confidence.

Zero Maintenance

No air lines, compressors, or adjustments — just durable, bolt-on components that deliver reliable performance mile after mile.

Made in the USA

Expertly designed, tested, and built in the USA — trusted nationwide and backed by a lifetime guarantee.

Support When You Need It. Strength When It Counts.

SMARTER SUSPENSION FOR EVERY TRAILER

Trailers work under constantly changing conditions — empty one trip, fully loaded the next. That shifting weight creates instability, bounce, and uneven wear that shorten component life and compromise safety.

SumoSprings are built to solve that. Made from microcellular polyurethane, they compress progressively as loads increase — soft enough to cushion vibration when empty, firm enough to control sway and bottoming when fully loaded.

The result is a smoother, quieter, and more stable tow — with no air lines, no compressors, and no maintenance. Just reliable, long-lasting support that helps every trailer track straighter and last longer.

THE MAINTENANCE-FREE SUSPENSION UPGRADE FOR EVERY TRAILER BUILD

Trailer SumoSprings replace or enhance the factory trailer suspension to deliver smoother, quieter towing and long-term stability.

They install quickly with standard tools, require no air systems or upkeep, and last for the life of the trailer. Whether you’re building cargo, utility, or equipment trailers, Trailer SumoSprings provide consistent, progressive support that protects components, cargo, and drivers. Trusted by leading trailer builders and commercial fleets across North America, Trailer SumoSprings turn every tow into a smoother, safer, and more predictable experience.

What Our Customers Are Saying

I installed SumoSprings on my F-250 before a cross-country trip pulling a fifth-wheel. The difference was immediate. No more sagging rear end or constant sway on the highway. The truck feels level and controlled, even in crosswinds or when semis pass. Hookups and long drives are now way less stressful, and my wife feels more comfortable on the road. Easily the best upgrade I’ve made for towing.

Daniel K. Moore

Ford F-250 Towing a Fifth-Wheel

My Silverado hauls a heavy enclosed work trailer almost daily, and the factory suspension just wasn’t cutting it. The back sagged, and every bump made the trailer feel like it was controlling the truck. After adding SumoSprings, the ride is much more stable, braking feels safer, and sway has been reduced dramatically. It’s made long days on the job site so much easier.

Sarah Jensen

Chevrolet Silverado 2500HD with Work Trailer

Towing my 24-foot boat used to mean white-knuckle drives, especially on uneven backroads heading to the lake. After installing SumoSprings, my Ram sits level, handles bumps without bottoming out, and the sway is nearly gone. Launching, loading, and towing all feel much more secure. I’d recommend these to anyone towing heavy loads — they transform the truck.

An Innovative Two Piece Solution, Designed to Replace Air Bags

Ditch the hassles of air bags and never worry about a puncture again. With a lifetime gaurantee, Rebel SumoSprings will outlast your vehicle.

No Lines or Compressors

SumoSprings are a set it and forget it solution. You'll never have to adjust pressure, replace air lines, or deal with costly compressors.

Bolt-On Installation

Easy, DIY installation can be completed easily in your drive way, keeping you on the road and out of the repair shops.

No Impact on Articulation

The innovative two piece design allows for full articulation. No fear of ripping bags here.

Why fight with compressors, leaks, and stiff metal helpers?

Better Than Airbags. Safer Than Spacers. Smarter All Around.

Airbags require constant upkeep — checking pressure, fixing leaks, rerouting lines. Metal spacers restrict travel and don’t add real spring support.

SumoSprings Rebel outperforms both. Its progressive foam delivers smooth damping, sway control, and bottom-out protection — without limiting articulation. And with no air to inflate, no adjustments to make, and no metal-on-metal fatigue, Rebel works when you need it and disappears when you don’t.
