Upgrade Your Chevelle, GTO, Skylark, or Cutlass With Our A-Body Rear Lower Control Arms

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 its limitations. Poor articulation and unwanted flex hold back your car’s true potential. That’s where our GP-R Series rear lower control arms come in. Designed to eliminate binding and improve suspension geometry, these arms deliver the traction, stability, and handling precision your build deserves.

Built for Strength. Engineered for Performance.

Our A-body rear lower control arms are built for serious performance, constructed from TIG-welded 4130 Chromoly tubing for exceptional strength and rigidity without excess weight. Each arm features opposing left- and right-hand threaded adjusters, allowing for easy rear-end alignment changes with the arms installed—no removal necessary. Low-friction rod ends provide maximum articulation, reduced bind, and precision control with minimal deflection, making them ideal for track-focused setups. Each set is finished with CNC-machined spacers for a precise fit and a durable satin black powder coat that looks as good as it performs.

Part of Our GP-R Series – Race-Bred Performance for the Track

These rear lower control arms are part of our GP-R Series—engineered for uncompromising performance on the track and in competition. Built for racers and hardcore enthusiasts, the GP-R line is all about maximizing capability under extreme conditions. Whether you’re chasing lap times, dialing in your setup for time attack, or building a no-compromise pro touring machine, GP-R components deliver the strength, adjustability, and precision you need to dominate.
