RV & Camper Vans

RVs and campers open the door to freedom — but they also test your suspension to the limit. Whether you’re hauling gear, crossing the country, or living full-time on the road, factory systems aren’t built to handle the weight, sway, and shock that comes with the lifestyle.

Product Spotlight – Explore with Confidence

Support for Every Rig, Large or Small

Purpose-built suspension upgrades for motorhomes, trailers, vans, and tow vehicles

SumoSprings Maxim – Designed for large motorhomes like those on the Ford F53 chassis, Maxim springs offer maximum surface area and progressive load support to control sway, protect components, and maintain ride height — even fully loaded.

Trailer SumoSprings – Replace traditional bump stops on camper and toy hauler trailers. These progressive springs absorb shock and help stabilize sway, protecting your trailer and everything inside.

SumoSprings Rebel – For trucks and SUVs towing campers, Rebel springs offer progressive compression with full articulation, eliminating rear-end sag and restoring confident control — no compressors needed.

Coil SumoSprings – Perfect for van builds and lighter RVs with front coils, these drop-in inserts add front-end support without sacrificing ride comfort.

I just put them on my Jayco Melbourne motor home and drove it for the first time. Wow, what a difference, like night and day. Love my Sumo Springs. This product is great and does what it says it will do. Thank you, 33
