Towing and Hauling

Towing a camper, fifth-wheel, toy hauler, utility,  or work trailer puts major strain on factory suspension, causing sag, sway, and poor handling. SumoSprings provide progressive, airless support for a smoother, safer tow — mile after mile.

A Stronger Tow, Without the Airbags
--

Engineered to make towing simple, stable, and stress-free
— no airlines, no leaks, no compromises.

Less Sway, More Control

Minimize body roll, sway, and bounce — even when fully loaded.

Completely Airless

No airlines, no compressors, no leaks — just reliable, maintenance-free support.

Direct-Fit Installation

Rebels mount to AirLift and Firestone brackets out of the box. Bolt-on simplicity.

Preserves Suspension

The Rebel’s two-piece design allows full articulation and maximum control.

From tow vehicle to trailer, we’ve got every bump covered.

Smarter Suspension for Every Tow

Towing isn’t just about power — it’s about control. That’s why SumoSprings products deliver progressive cushioning that engages smoothly as load increases. They absorb harsh impacts, stabilize the ride, and protect passengers and cargo from road shock. And unlike airbag systems, they never need monitoring, adjusting, or fixing. No matter what you're hauling, you’ll feel the difference from the first mile.

Product Spotlight – SumoSprings Rebel

Ditch the Airbags. Keep the Brackets.

Ditch the Airbags. Keep the Brackets.
The two-piece Rebel spring is the airless upgrade your truck deserves.

SumoSprings Rebel replaces traditional airbags with a progressive, two-piece spring that compresses under load and separates at full droop. That means smoother towing with full suspension travel — no air leaks, no blowouts, no compressors. And because Rebels mount directly to many existing AirLift and Firestone brackets, you can upgrade without removing your current setup.

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

Never Deal with Leaks Again

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.
