H&R 29879 Sport Spring Kit - Progressive Rate Lowering Springs

Manufactured at H&R's ISO 9001 certified facility in Germany, these springs are crafted from a proprietary 54SiCr6 spring steel rated at 290,000 psi tensile strength — ensuring exceptional resilience and long-term durability.

Each spring is also shot-peened during the manufacturing process, a treatment that increases spring fatigue life by over 200%, making these a premium, long-lasting suspension upgrade over standard OEM springs.
