Upgrade your 1963–1972 Chevy C10 with a rear suspension system designed to improve stance, ride quality, and handling. This QA1 bolt-on rear suspension system converts your truck’s factory coil-spring rear suspension to fully adjustable coilovers, giving you greater control over ride height and suspension performance.
Designed specifically for coil-spring C10 trucks, this system provides up to 6 inches of ride height adjustment, allowing you to achieve the perfect stance while improving stability and handling.

Tune Your Ride Quality and Handling
This system features single adjustable coilovers, allowing you to easily fine-tune both compression and rebound together with a simple adjustment.
With 18-position adjustment knobs, you can quickly dial in a comfortable street ride or firm up the suspension for improved control and responsiveness.
Relocating the coilovers outside the frame rails and closer to the wheels improves suspension leverage and cornering stability, helping your truck feel more planted and predictable.
Additional suspension geometry adjustments include:
- Adjustable panhard bar to keep the rear axle centered
- Multiple mounting points for roll center tuning based on ride height
- Integrated pinion angle adjustment for proper driveline alignment
Installs Without Removing Your Bed
QA1 designed this system for straightforward bolt-on installation without the need to remove the truck bed.
The kit mounts directly to your C10 frame with minimal fabrication required, making it an ideal upgrade for both home builders and professional installers.
The design also provides clearance for popular aftermarket rear-mounted fuel tanks, ensuring compatibility with many common truck builds.
Easily Adjust Stance and Pinion Angle
This suspension system offers multiple adjustment points to help dial in your truck’s stance and driveline alignment.
Whether you're aiming for an aggressive 6-inch drop or a more subtle ride height change, the system allows you to adjust:
- Ride height
- Wheelbase positioning
- Pinion angle
The integrated pinion angle adjustment eliminates the need for shims or spacers, making driveline setup easier and more precise.
