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 can hold back your car’s true potential. That’s where our GP-S Series rear lower control arms come in. Designed to improve suspension geometry and reduce deflection over stock stamped steel arms, these control arms offer better traction, stability, and confidence on the street or spirited backroad. PLEASE NOTE THESE DO NOT HAVE SWAY BAR MOUNT HOLES, AS THEY ARE INTENDED TO BE USED WITH A CHASSIS MOUNTED SWAY BAR. WE STRONGLY ADVISE AGAINST RUNNING A CONTROL ARM MOUNTED SWAY BAR DUE TO THEIR POOR PERFORMANCE.

Street-Ready Strength. Reliable Performance.

Our A-body rear lower control arms are built from 1.5" x .156" DOM steel tubing for superior strength and durability over factory components, without the complexity or cost of race-oriented upgrades. Each arm features precision-welded construction and high-quality Energy Suspension™ polyurethane bushings to reduce unwanted movement and provide a firmer, more responsive ride. These maintenance-free bushings help minimize deflection while isolating road noise and vibration—perfect for high-performance street builds and occasional track use. Every set is finished in a durable satin black powder coat for long-lasting protection and clean aesthetics.

Part of Our GP-S Series – Engineered for the Street. Ready for the Track.

These rear lower control arms are part of our GP-S Series—our street-optimized product line built specifically for pro touring muscle cars that demand high performance without sacrificing real-world drivability. Whether you're carving up canyon roads, dominating spirited weekend cruises, or dipping into the occasional autocross, GP-S components deliver the ideal balance of refined street manners and confident, track-capable performance.
