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

QA1's GM 2.0 Control Arms offer increased positive caster, reduced unsprung weight, and improved performance. They feature integrated, stronger-than-OEM, rebuildable ball joints for durability. Billet cross shafts and double-sheer lower mounts, coil-over ready, provide a clean installation. These arms are a direct upgrade for 1978-1988 GM G-Body vehicles, enhancing handling, ride quality, and vehicle stance. They improve suspension geometry and are compatible with QA1 Pro-Coils and full suspension kits (not compatible with OE springs; must be used with a coil-over system). Sold in pairs, they include bump stops, adjustable steering stops, and mounting hardware. Made from high-strength, low-alloy steel for optimized thinner wall construction, resulting in lighter weight. The integrated low-maintenance ball joints have dust boots, are stronger, and are rebuildable for different ball stud lengths. Compatible with OE or drop spindles, they increase positive caster for stability. The Pro Touring Series arms feature a 1" longer upper ball joint stud for increased negative camber gain. Low friction ball joints are adjustable, and ultra-low friction composite bushings eliminate flex. Compatible with all QA1 single adjustable, double adjustable, and MOD Series Pro Coil-Over shocks. They mount in the OE location without cutting or welding and accommodate factory or aftermarket disc brakes.
