73-87 Chevy & GMC C10 Squarebody Coilover Front Kit (Bolt-On)

73-87 C10 Squarebody Coilover Front Kit - #130-2001C

**This product will have a lead time; please call to verify expected wait**

The GSI 1973-1987 C10 Coilover Front Kit replaces your factory front crossmember and suspension with a modern power rack and pinion & coilover-based system designed for a low ride height, improved handling, and increased steering response.

This kit is ideal for builders who want a sport-focused setup without air ride, offering consistent suspension control for street performance, autocross, and aggressive show builds.

Engineered for Low Stance & Performance

Designed and manufactured at our facility in Chandler, Arizona, this front suspension system is built using laser-cut & CNC-formed ASTM A1011 parts to ensure proper fitment and repeatable results.

Updated suspension geometry improves ride quality, reduces camber change through travel, and enhances steering feel. The narrowed front track width allows for improved wheel clearance when running wider wheels, while the wheel position is relocated within the wheel opening for a more balanced appearance.
