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 SSA39 has an additional load leveling capacity of 3,400 lb.
Please Note: SuperSprings International products are specifically designed for vehicles equipped with factory suspension. We cannot guarantee their compatibility with aftermarket products or parts. For questions about fitment on your specific vehicle, please contact us.
Definitely worked for what I needed them for. Raised out food truck considerably higher. Also improved drivability and ride comfort. Would definitely recommend this product.
