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

QA1's Pro-Touring Control Arms are designed for autocross and road course handling. 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 optimal tire contact and superior cornering grip. The ball joints are adjustable and rebuildable for tuning with different stud lengths. These arms are configured for QA1 Pro Coil Systems with double shear lower mounting. Constructed from high-strength tubing and billet aluminum cross shafts, they are among the lightest on the market with improved strength and durability. They are robotically welded and high-quality powder-coated. These street control arms are 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 those numbers.
