H&R 29666 Sport Lowering Springs Set

The H&R 29666 Sport Springs are a premium lowering spring kit engineered to deliver a sportier stance and sharper handling without sacrificing everyday ride comfort. Manufactured at H&R's ISO 9001 certified facility in Germany, every spring in this kit is built to exacting standards using proprietary materials and in-house production processes.

Constructed from special 54SiCr6 spring steel with a tensile strength rated at 290,000 psi, these springs offer exceptional resilience and durability that outlasts conventional automotive coil springs. Each spring is shot-peened during manufacturing to extend service life by over 200%, ensuring long-term performance without sag or set.

H&R Sport Springs feature a progressive spring rate design that lowers the vehicle's center of gravity, reduces body roll, and tightens handling response — all while maintaining a comfortable, street-friendly ride. The reduced fender well gap delivers an aggressive, performance-ready stance, and the lower aerodynamic profile can contribute to improved fuel efficiency.
