QA1 52737 Street Performance Front Lower Control Arm Kit for 1964-1972 GM A/G-Body

Fits select 1964-1972 GM A/G-Body vehicles, including Chevrolet Chevelle, El Camino, Monte Carlo, Pontiac GTO, and Oldsmobile Cutlass.

QA1 Street Performance Lower Control Arms are the ideal suspension upgrade for enthusiasts who prioritize ride quality and stability during long-distance cruising. These arms are specifically configured for compatibility with QA1 Pro Coil Systems, utilizing a double shear lower mounting point to ensure maximum strength and component security.

Built from high-strength tubing paired with billet aluminum cross shafts, these arms are significantly lighter than factory stamped-steel components while offering superior durability. Each arm is robotically welded and finished with a high-quality powder coating for corrosion resistance. To improve handling without sacrificing comfort, QA1 uses low-friction polyurethane bushings that isolate road noise while maintaining a stiff, responsive feel. This kit also features integrated ball joints that are stronger than OE units, providing a longer service life and improved safety.
