1968-1972 A-Body Rear Control Arm Kit - GP-R

Upgrade Your Chevelle, GTO, Skylark, or Cutlass With Our A-Body Rear Control Arm Kit – GP-R Series

If you're driving a GM A-body—like a Chevelle, GTO, Cutlass, or Skylark—you know the factory triangulated four-link rear suspension has limitations when it comes to high-performance handling. Our GP-R Series rear control arm kit is engineered to fix those issues. Designed for racers and hardcore enthusiasts, this kit includes both upper and lower control arms crafted from TIG-welded 4130 chromoly tubing for exceptional strength and durability. These arms improve suspension geometry, reduce deflection, and deliver precise axle control under extreme conditions.

Race-Ready Strength. Competition-Proven Performance.

The GP-R rear control arm kit features fully chromoly construction with low-friction rod ends that maximize articulation while minimizing deflection and weight. Built for pro touring, time attack, and autocross, these arms offer the strength and precision you need to push your A-body to the limit. Precision CNC-machined spacers ensure a perfect fit, and a durable satin black powder coat finish provides long-lasting protection and a professional appearance.

Part of Our GP-R Series – Engineered for Track and Street

These rear control arms are part of our GP-R Series—our race-bred product line engineered for uncompromising performance on the track and street. Whether you’re chasing lap times or building a no-compromise muscle car, GP-R components deliver the strength, precision, and reliability needed to dominate.
