H&R 29312-3 Sport Lowering Springs Set

The H&R 29312-3 Sport Springs are a premium drop-in lowering spring set engineered to deliver a sportier stance and improved handling characteristics while retaining a comfortable, street-friendly ride. Manufactured at H&R's ISO 9001 certified facility in Lennestadt, Germany, these springs are built to exacting tolerances using proprietary 54SiCr6 silicon-chromium spring steel, rated at an impressive 290,000 PSI tensile strength — one of the highest in the industry.

H&R Sport Springs utilize a progressive spring rate design wherever possible, allowing the spring to respond softly over minor road imperfections while firming up under aggressive cornering loads. This makes them an ideal upgrade for enthusiasts who want real performance gains without sacrificing daily driveability. The springs are fully compatible with OE shock absorbers as well as most quality aftermarket dampers.
