QA1 78-88 GM G Body Pro Touring Upper Control Arm Kit

QA1's Pro-Touring Control Arms are the answer to your handling needs for autocross and road course. Featuring QA1's Ultra Low Friction Ball Joint, these upper control arms are designed to eliminate flex and provide bind-free movement, improving your vehicle's performance on tight corners.

The one-inch longer upper ball joint stud enhances camber gain, ensuring optimal tire contact with the road for superior cornering grip. These ball joints are adjustable and rebuildable, allowing you to fine-tune them with different stud lengths according to your suspension setup.

These control arms are configured for QA1 Pro Coil Systems and feature double shear lower mounting for added durability. The high-strength tubing, paired with billet aluminum cross shafts, ensures that these arms are some of the lightest available on the market while delivering superior strength and durability.

Robotically welded and high-quality powder coated, these arms not only perform exceptionally but also look great on your G Body. When used together, these arms are engineered to add 3-4 degrees of caster and 0.5 to 1 degree of negative camber, while using them independently adds approximately half of those values.
