QA1 Street Performance Front Upper Control Arm Kit for Select 1964-1972 GM Buick, Chevrolet, Oldsmobile, and Pontiac (52722)

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

The QA1 Street Performance Upper Control Arm Kit is engineered to correct outdated front-end geometry on classic GM A and G-Body platforms. These arms are specifically configured for use with QA1 Pro Coil Systems featuring double-shear lower mounting. By optimizing the suspension's pivot points, these arms are designed to add 3 to 4 degrees of caster and 0.5 to 1 degree of negative camber when installed together, significantly improving directional stability and cornering grip over factory settings.

Built for the rigors of street performance and long-distance cruising, these arms utilize high-strength tubing paired with billet aluminum cross shafts to achieve a superior strength-to-weight ratio. Each arm is robotically welded and finished with a durable powder coat. To ensure a comfortable ride without sacrificing precision, QA1 utilizes low-friction polyurethane bushings that isolate road noise while maintaining the stiffness required for responsive handling. The integrated high-quality ball joints provide increased strength and service life compared to original equipment components.
