SuperSprings - SumoSprings Rear Suspension Helper Springs Black

SuperSprings SumoSprings rear suspension helper springs provide progressive load support and improved stability for selected Toyota and Lexus vehicles. The black -47 density delivers 1,800 lb capacity at 50% compression and helps control rear-end sag, sway and harsh suspension movement. Supplied as a pair with mounting hardware.

PROGRESSIVE LOAD SUPPORT

Manufactured from proprietary closed micro-cellular urethane, SumoSprings respond progressively as the rear suspension compresses, while providing smooth damping characteristics and greater control when loaded.

MAINTENANCE-FREE DESIGN

Unlike an air suspension system, SumoSprings require no compressors, air lines or pressure adjustments. Their durable construction is designed for fit-and-forget operation.
