H&R 54680-2 Sport Lowering Springs Front and Rear Kit

The H&R 54680-2 Sport Springs are a front-and-rear lowering spring kit engineered to deliver a sportier stance and sharper handling without sacrificing everyday ride comfort. Manufactured entirely in-house at H&R's ISO 9001 certified facility in Germany, these springs are built to exacting standards and backed by H&R's reputation as a leader in performance suspension.

Constructed from proprietary (hf) 54SiCr6 high-fatigue spring steel and shot-peened during production, these coil springs offer exceptional tensile strength, long-term resilience, and a service life that outlasts conventional OE springs. Every spring is 100% individually tested before leaving the factory.

The progressive spring rate design allows the spring to adapt dynamically to road conditions — softening for a comfortable cruise and firming up when cornering loads increase. This delivers a balanced combination of daily drivability and responsive handling that fixed-rate springs simply cannot match.
