H&R 28947-4 Sport Lowering Springs Set

The H&R 28947-4 Sport Springs deliver the ideal balance of aggressive stance and everyday drivability, making them one of H&R's most popular suspension upgrades. Engineered and manufactured at H&R's ISO 9001 certified, TÜV-approved facility in Lennestadt, Germany, these coil springs are built to exacting standards with full in-house quality control on every unit produced.

Crafted from a special high-fatigue (hf) 54SiCr6 spring steel rated at 290,000 psi tensile strength, each spring undergoes a shot-peening process that increases service life by more than 200% compared to conventional springs. Every spring is 100% tested before leaving the factory, ensuring consistent performance and reliability.

H&R Sport Springs lower the vehicle's center of gravity for reduced body roll, improved cornering grip, and a more aggressive fender-well stance — all while retaining a ride quality suitable for daily street driving. A progressive spring rate design smooths out road imperfections without the harshness associated with cheaper lowering alternatives. These springs are compatible with OEM dampers as well as aftermarket sport shocks, and feature a durable powder coat finish for corrosion resistance.
