Belltech Coilover System - 88-98 C1500

⚠️ Minimum 1.25" Rotor

Belltech has been lowering the Chevy OBS since the late 1980s, and few vehicles have shaped our legacy like the 1988–1998 Chevrolet C1500. After celebrating our 40th anniversary, we set out to give this platform a modern suspension solution worthy of its reputation. The result is a complete bolt-on front and rear coilover system with a 4-link conversion kit that delivers an aggressive stance, modern handling, and exceptional ride quality. Whether it’s a track day, cruising the street, or daily driving, this system provides the comfort, control, and adjustability enthusiast’s demand.
