SuperSprings SSA13.5 Single Self-Adjusting Suspension Stabilizing System Rear (1,700 lb Capacity) Manufacturer: SuperSprings Manufacturer Part #: SSA13.5 Thoroughbred Diesel Part #: SSPSSA13.5
SuperSprings are a simple, bolt-on, steel helper spring that eliminates rear-end sag and stabilizes sway & body roll. Built from high-grade shot peened steel, this suspension solution allows you to load up without sacrificing your ride quality.
The SuperSpring includes a patented roller shackle on each end that allows for self-adjustment as weight is changed. This is particularly helpful as you add water, tools or heavy gear to your vehicle.
The SSA13.5 has an additional load leveling capacity of 1,700 lb.
