SuperSprings International offers a solution that enhances the level-load-carrying ability of the Ram 2500’s newly redesigned rear coil spring suspension.

SumoSprings are comprised of a proprietary microcellular urethane that progressively compresses under load, providing smoother engagement than rubber bump stops. They can be compressed by 80 percent of their original height with full memory rebound to provide maximum support when needed. Unlike air bag systems, SumoSprings are completely maintenance-free and will never sag or leak. They are oil-, salt- and UV-resistant, providing a durable “fit-it-and-forget-it” solution even in harsh environments.

The single-piece microcellular urethane SumoSpring Solos also offer minimal outward expansion under load, so they can be mounted in tight spaces. SumoSprings for the Ram 2500 (P/N SSR-302) are available in different densities to meet the needs of medium-duty and heavy-duty users.
