H&R 54290 Sport Springs Lowering Coil Spring Set

The H&R 54290 Sport Springs are a premium lowering coil spring set engineered and manufactured at H&R's ISO 9001 certified facility in Lennestadt, Germany. Designed as a direct replacement for factory springs, they deliver a sportier ride height and significantly improved handling dynamics while retaining the comfort expected of a street-driven vehicle.

H&R Sport Springs are crafted from a proprietary 54SiCr6 high-fatigue spring steel, rated at 290,000 psi tensile strength, and are shot-peened to extend service life by more than 200%. The result is a spring set that is strong, resilient, and far more durable than standard OE coil springs — engineered never to set or sag over time.

The progressive spring rate design intelligently adapts to road conditions, providing a compliant, comfortable feel during everyday cruising while stiffening up when cornering demands it. This makes the H&R 54290 one of the most well-rounded suspension upgrades available for street use. A reduced fender well gap improves visual stance, and the lower center of gravity reduces body roll and aerodynamic drag for a more streamlined, efficient profile.
