1973-87 Chevy C-10 Heidts Heavy Duty Bolt-On 4 Link Rear Suspension

The Heidts Heavy Duty 4-Link Rear Suspension Kit for the 1973–1987 Chevy C-10 (Squarebody) is designed to eliminate the limitations of the factory leaf spring setup. By moving to a 4-link configuration, you gain significantly better axle control, improved traction for high-horsepower builds, and a much more refined ride quality for both street and track performance.

Performance and Adjustability

• Optimized Axle Control: This system replaces factory leaf springs with a modern 4-bar setup, eliminating the "wheel hop" and spring wrap that often plague high-torque trucks.

• Precision Tuning: The kit features double-adjustable link tubes, allowing you to fine-tune your pinion angle and wheelbase. This level of adjustability is essential for maintaining proper driveline geometry after lowering the vehicle.

• Lateral Stability: Includes an adjustable panhard bar to keep the rear axle perfectly centered under the frame, providing predictable handling during hard cornering and high-speed maneuvers.

• Custom Stance: Paired with adjustable coil-over shocks, this kit allows you to dial in your preferred ride height and dampening stiffness, moving away from the "one-size-fits-all" nature of leaf springs.

Heavy-Duty Engineering

• Rugged Hardware: Built to handle the weight and demands of a full-size pickup, the kit utilizes high-strength 1-inch rod ends and heavy-wall link tubes.

• Bolt-On Convenience: Engineered as a bolt-on solution, this kit is designed to integrate into the existing C-10 frame with minimal hassle, providing a professional-grade suspension overhaul without the need for extensive fabrication.

• Integrated Safety: The system is designed with a built-in drive shaft loop, offering an added layer of safety and structural rigidity to the rear chassis.

Fitment and Compatibility

• Track Width: Optimized for a 64-inch track width, which is the standard for Squarebody C-10 performance applications.

• Coil Spring Trucks: This kit is designed specifically for trucks that came from the factory with coil spring rear suspensions.

  Note: Trucks originally equipped with factory leaf springs will require additional fabrication to provide the necessary mounting points for the 4-link bars.

• Short Bed Note: While designed for a wide range of Squarebody trucks, short bed frames may require minor additional modifications during the installation process for perfect clearance.

Available Options:

• Adjustable Coil-Overs: Billet shocks available in various finishes to customize ride quality.

• Fabricated Axle Housing: Optional 9-inch rear housing with 4-link brackets pre-installed for a simplified drivetrain solution.

• Chassis Reinforcement: Subframe connectors are available to further stiffen the C-10’s long-wheelbase chassis.
