QA1 64-72 GM A/G-Body Pro-Touring Upper Control Arm Kit - Front

QA1’s Pro-Touring Control Arms are designed for autocross and road courses. They feature QA1’s Ultra Low Friction Ball Joint to eliminate flex and provide bind-free movement. The one-inch longer upper ball joint stud improves camber gain for superior cornering grip. The ball joints are adjustable and rebuildable. Configured for QA1 Pro Coil Systems with double shear lower mounting. Constructed with high-strength tubing and billet aluminum cross shafts, making them lightweight while improving strength and durability. Robotically welded and high-quality powder coated. Designed to add 3-4 degrees of caster and 0.5 to 1 degree of negative camber when used together. When used independently they will add approximately half of the preceding numbers.
