QA1 64-72 GM A/G-Body Drag Race Upper Control Arm Kit - Front

QA1's GM 2.0 Control Arms offer increased positive caster, reduced unsprung weight, and improved performance. They feature an integrated, rebuildable ball joint design, billet cross shafts, and double-sheer lower mounts, making them coil-over ready. These arms are designed for drag racing and are a bolt-in upgrade for original or worn tubular control arms, improving handling, ride quality, and vehicle stance. They enhance factory suspension geometry and are compatible with QA1 Pro-Coils and full suspension kits. Note: Not compatible with OE springs; must be used with a coil-over system.
