QA1 70-81 GM F-Body, 73-77 A-Body, 75-79 X-Body, 71-96 B-Body Pro Touring Upper Control Arm Kit

QA1’s Pro Touring Upper Control Arms are the perfect upgrade for your GM F-Body, A-Body, X-Body, or B-Body vehicle, delivering exceptional handling performance on both autocross and road course tracks. Engineered with QA1's Ultra Low Friction Ball Joint, these control arms eliminate flex and ensure bind-free movement, enhancing overall vehicle control during aggressive driving.

The longer upper ball joint stud design improves camber gain, optimizing tire contact for superior cornering grip. These adjustable and rebuildable ball joints allow for custom tuning, and the arms are specifically configured for QA1 Pro Coil Systems with double shear lower mounting. Featuring high-strength tubing and billet aluminum cross shafts, these control arms are among the lightest and strongest on the market, combining durability with performance. Each control arm is robotically welded and powder-coated for a clean, long-lasting finish, adding 3-4 degrees of caster and 0.5-1 degree of negative camber when used together.
