Upgrade your 1966–1967 GM A-Body Chevelle, GTO, Skylark, or Cutlass with Speedtech’s rear coilover conversion kit. Designed for builders who want precise ride-height control, improved handling, and easy shock tuning, this kit brings race-inspired performance to classic muscle cars without sacrificing drivability or ride comfort. Perfect for pro-touring builds, street performance cars, and weekend track machines.
Performance & Stance
Speedtech’s rear coilover conversion kit replaces factory coil springs and shocks with a fully adjustable coilover system engineered for strength, tunability, and control. The included QA1 double-adjustable coilovers allow precise rebound and compression tuning for optimal ride quality and performance. This setup improves traction, reduces body roll, and gives your A-Body the aggressive stance modern builders demand—all with the reliability expected from Speedtech’s race-proven designs.
Bolt-In Convenience
Engineered with laser-cut brackets for a precise fit, this kit installs using existing mounting points -no cutting or welding required. Designed for builders who value strength and simplicity, it converts your factory rear suspension into a performance-tuned coilover system while maintaining compatibility with stock or aftermarket rear ends. Every component is built to handle the power and torque of modern drivetrains.
