QA1s C10 Bolt-On Rear Suspension System is the ultimate upgrade for truck owners looking to transform their coil-spring rear suspension into fully adjustable coilovers. Designed for 1963-1972 Chevy C10 trucks originally equipped with coil springs, this system delivers up to 6 inches of total drop, allowing for that perfect stance while improving performance and handling.

TUNE YOUR PERFORMANCE & RIDE COMFORT

Double-adjustable coilovers are perfect for drivers seeking optimal performance from their truck. The independent adjustment of compression and rebound allows you to fine-tune handling or straight-line performance for any driving condition. With 18-position adjustment knobs that are easy to access, simply reach in to make your tuning adjustments at the base of the shock.

By relocating the coil-overs to the outside of the frame rail, closer to the wheels, the system delivers better cornering stability, making your truck feel more planted and responsive. The adjustable panhard bar ensures your rear axle stays centered during aggressive cornering, while the multiple mounting points allow you to adjust the roll center geometry based on your ride height.

Plus, with ample clearance for popular aftermarket rear-mounted fuel tanks, QA1 ensures your build isnt limited by your suspension system.
