SuperSprings SSR-206-54: SumoSprings Yellow Rear for Chevy Express 4500 & GMC Savana 4500 - Review & Buying Guide Review

Simple, simple, easy to assemble. Use them on Coachmen Freelander class 24 ft c. Solved, and the rear suspension hit rock bottom. Big fan. Costs money.

I added sumo front and rear springs to my Chevy 4500 RV on a 14,000 pound chassis. Together, they've gone from gross, painful, and downright awful to outstanding. The hard bumps found on concrete roads with large expansion joints are a thing of the past. Sometimes I crashed into bridge crossings and the whole RV smacked, cupboards and dishes rattled.
