63-72 C10 Coilover Front Kit

63-72 Coilover Front Kit - #125-2001C

The GSI 1963-1972 C10 Coilover Front Kit replaces your factory front crossmember and suspension with a modern 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.

A modern power rack and pinion replaces the factory steering system, delivering tighter response and improved control.

- CPP Stock Spindles – Factory height spindle with the spindle pin located at the bottom, maintaining original suspension geometry and ride height.

- CPP 2.5" Modular Drop Spindles (Big Brake) - Lowers the vehicle 2.5" using a high-strength modular hub design. This spindle is purpose-built for maximum clearance, allowing for seamless installation of high-performance 13"–14" Big Brake kits.

- CPP 2.5" Modular Drop Spindles with 6087DBK (Stock & Big Brake) -  The 6087DBK bracket gives you a 2.5" drop while keeping your 12" Stock Brakes.
