QA1’s 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.
INSTALLS WITHOUT REMOVING YOUR BED
Forget about complex installs or needing to remove the truck bed—QA1’s bolt-on design ensures a smooth, hassle-free installation. The system is designed to bolt directly to your C10, reducing the need for custom fabrication or complicated modifications, making it easy for at-home installs.
Plus, with ample clearance for popular aftermarket rear-mounted fuel tanks, QA1 ensures your build isn’t limited by your suspension system.
EASILY ADJUST STANCE & PINION ANGLE
QA1’s C10 rear suspension system offers full adjustability to meet your specific goals. Whether you’re aiming for an aggressive 6-inch drop or a more subtle stance, this system gives you complete control over your ride height, wheelbase, and pinion angle, allowing you to achieve the exact stance and performance you desire. A standout feature of the QA1 kit is its adjustable pinion angle, which eliminates the need for clumsy spacers.
