H&R 54630 Sport Springs Lowering Spring Set

H&R Sport Springs (PN 54630) deliver the ideal balance of improved handling and a comfortable street-oriented ride. Engineered and manufactured at H&R's ISO 9001 certified facility in Germany, these springs are built to exacting standards using a proprietary 54SiCr6 spring steel alloy rated at an exceptional 290,000 psi tensile strength — providing unmatched resilience and long-term durability over conventional spring steel.

Designed as a direct OEM replacement upgrade, H&R Sport Springs lower your vehicle's center of gravity for a more aggressive stance and sharper cornering response, all while maintaining the ride comfort you expect from a daily driver. Unlike stiffer coilover setups, H&R Sport Springs are specifically engineered for street use, offering a refined, progressive spring rate that reduces body roll without introducing unwanted harshness.

• Average lowering of 1.5 to 2.0 inches for improved stance and handling
