QA1 Rear Suspension System (R231-200) - 1973-1987 Chevrolet C10

Upgrade your Squarebody’s ride quality, handling, and performance with the QA1 Rear Suspension System, designed for 1973-1987 Chevrolet C10 trucks using a GM 12-bolt rear housing. This complete system replaces outdated leaf springs with a modern torque arm setup, delivering improved traction, smoother ride quality, and more predictable control whether cruising or pushing your truck harder.

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 and allows the shocks and springs to perform more effectively. The result is a more planted, stable, and confidence-inspiring driving experience.

This system includes double adjustable QA1 shocks, allowing independent tuning of compression and rebound. This advanced adjustability gives you the flexibility to dial in ride quality and handling characteristics to match your build and driving style.
