Product Description

The H&R 29230-1 Sport Lowering Spring Kit is engineered specifically for AWD Mercedes-Benz W203 C-Class models from 2003 through 2007 (C240, C280, C320, C350 in both sedan and wagon). Bringing a subtle yet impactful drop of approximately 1.3 in at the front and 1.2 in at the rear, this kit lowers the center of gravity, enhances stance, improves cornering, and reduces body roll--all while maintaining daily drive comfort.

Crafted in Germany from durable, shot-peened 54SiCr6 spring steel and protected with a resilient powder-coat finish, these springs are ISO 9001 and TUV certified. The progressive design works seamlessly with both OE and sport dampers--though pairing with performance shocks like Bilstein is recommended for optimal longevity. Tailored for 4MATIC AWD suspension, H&R 29230-1 preserves original geometry and ride characteristics. A professional alignment post-installation is advised.
