QA1 Rear Suspension System (R230-170) - 1973-1987 Chevrolet C10

Upgrade your Squarebody’s performance, ride quality, and stance with the QA1 Rear Suspension System, designed for 1973-1987 Chevrolet C10 trucks. This complete, engineered solution replaces outdated leaf spring setups with a modern torque arm suspension, delivering improved traction, smoother ride quality, and more predictable handling on the street or in performance applications.

At the core of this system is QA1’s torque arm design, which controls rear axle movement under acceleration. By separating drivetrain forces from suspension movement, it reduces axle wrap, improves traction, and allows the shocks and springs to perform more effectively. The result is a more planted, controlled, and confidence-inspiring driving experience.

This system is equipped with double adjustable QA1 shocks, offering independent tuning of compression and rebound. This allows you to dial in the perfect balance between comfort and performance, making it ideal for builds that demand maximum adjustability.
