52564 QA1 78-88 GM G Body Pro Touring Lower Control Arm Kit

QA1's Pro-Touring Control Arms are the answer to your handling needs for autocross and road course. Designed with QA1's Ultra Low Friction Ball Joint, these control arms eliminate flex and provide bind-free movement for superior performance.

The one-inch longer upper ball joint stud improves camber gain, ensuring that the tire contact patch remains optimal for excellent cornering grip. QA1's ball joints are adjustable and rebuildable, allowing for tuning with different stud lengths to suit your setup.

Configured for QA1 Pro Coil Systems with double shear lower mounting, these control arms combine high-strength tubing with billet aluminum cross shafts, resulting in a lightweight yet highly durable design. The arms are robotically welded and feature a high-quality powder coat finish for lasting durability and style.

These arms are engineered to add 3-4 degrees of caster and 0.5 to 1 degree of negative camber when used together, improving overall suspension geometry. When used independently, they will add approximately half of these adjustments.
