H&R 28923-1 Sport Springs Lowering Spring Kit

The H&R 28923-1 Sport Springs are a premium lowering spring kit engineered and manufactured at H&R's ISO 9001 certified facility in Germany. Crafted from a proprietary 54SiCr6 high-strength spring steel rated at 290,000 PSI tensile strength, these springs are shot-peened to extend service life by over 200%, ensuring they will not set or sag over time.

H&R Sport Springs deliver an ideal balance of lowered stance and daily-driver comfort. The progressive spring rate design lowers the vehicle's center of gravity and reduces body roll for sharper, more confident handling — without the harsh ride associated with less-engineered alternatives. The reduced fender well gap gives your vehicle a cleaner, more aggressive appearance straight from the factory.
