H&R 51860 Sport Spring Lowering Kit

The H&R 51860 Sport Springs are H&R's number one selling suspension upgrade, engineered to deliver a lower, more aggressive stance without sacrificing everyday ride quality. Manufactured at H&R's ISO 9001 certified facility in Germany, every spring is crafted from a proprietary 54SiCr6 spring steel rated at 290,000 psi, providing exceptional tensile strength and long-term resiliency.

H&R Sport Springs feature a progressive spring rate design that lowers the vehicle's center of gravity and reduces body roll for sharper, more confident handling. Unlike stiffer aftermarket options, these springs are specifically tuned for street use — delivering a comfortable, fun-to-drive experience alongside improved performance. An added benefit of the reduced ride height is a lower aerodynamic profile, which can contribute to improved fuel efficiency.

Each spring goes through a rigorous manufacturing process that includes CNC spring coiling for precise tension and dimensions, heat treatment to relieve internal stress, and a shot-peening process that extends spring life by over 200%. A pre-setting operation prevents sag over time, and a durable multi-stage coating protects against corrosion.
