QA1 Pro-Touring Front Upper Control Arm Kit for Select 1970-1996 GM F/A/X/B-Body (MPN 52518)

Fits select 1970-1996 GM A-Body, B-Body, F-Body, and X-Body vehicles, including Chevrolet Camaro, Caprice, Impala SS, and Pontiac Firebird. This QA1 Pro-Touring Upper Control Arm kit is engineered to correct outdated front-end geometry, making it an essential upgrade for autocross, road course, and performance street applications.

These arms utilize a 1-inch longer upper ball joint stud to significantly improve camber gain, maintaining an optimal tire contact patch during hard cornering. The construction features high-strength steel tubing paired with billet aluminum cross shafts to provide a superior strength-to-weight ratio while reducing unsprung weight. Each arm is robotically welded and finished with a durable powder coating for long-term corrosion resistance. For those using QA1 Pro Coil systems, these arms are configured for double-shear lower mounting to ensure bind-free movement and maximum rigidity.
