H&R 29255-4 Sport Lowering Springs - Progressive Rate, 54SiCr6 Steel

The H&R 29255-4 Sport Springs are a performance lowering spring set engineered and manufactured at H&R's ISO 9001 certified facility in Germany. Built from proprietary 54SiCr6 spring steel rated at 290,000 psi tensile strength, these springs deliver the ideal balance of improved handling and daily drivability.

H&R Sport Springs feature a progressive spring rate design that lowers the vehicle's center of gravity, reduces body roll, and eliminates the excessive fender well gap of a stock suspension — all without sacrificing ride comfort. The streamlined stance also reduces aerodynamic drag for a more efficient, planted driving experience.
