Eibach PRO-TRUCK lowering kits are carefully designed to lower the center of mass of today's most popular trucks and SUV's, improving handling, increasing safety and enhancing appearance all at the same time. Like every Eibach Performance Spring Package, our PRO-TRUCK sport lowering kits are the perfect complement to increasingly popular large-diameter wheel-and-tire packages. Precisely engineered and manufactured Eibach PRO-TRUCK lowering components deliver superior handling, improved aerodynamics, enhanced transient response and rugged durability-all while maintaining the smooth, compliant ride for which Eibach is famous. And unlike many competitors' products, Eibach PRO-TRUCK kits never require add-on retaining straps to keep your springs in place!.
