1968-1972 GM A-Body Lower Rear Control Arms - GP-R Series

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 GT 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 constructed from TIG-welded 4130 Chromoly tubing, giving them the strength and rigidity needed for serious performance without excess weight. Each arm features opposing left-hand and right-hand threaded adjusters, making it easy to dial in your rear end position with the arms installed—no need to remove them to fine-tune your setup.

Choose your bushing style to suit your build:

• Polyurethane Bushings – Ideal for street and spirited driving, offering reduced deflection compared to factory rubber while maintaining ride comfort.
• Low-Friction Rod Ends – Perfect for track-focused setups, delivering maximum articulation, reduced bind, and precision control with minimal deflection.

We finish each set with CNC-machined spacers for a precise fit and a durable satin black powder coat that looks as good as it performs.

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.
