QA1 52964 Lower Control Arms 78-88 GM G-Body

QA1's GM 2.0 Control Arms provide increased positive caster compared to OE arms, are among the lightest arms available featuring lower unsprung weight and improved performance without sacrificing durability. They include QA1's integrated ball joint design; stronger than OEM, rebuildable for tunability, and providing long-term reliable service. These arms feature billet cross shafts for reduced weight and durability for the long haul. Double-sheer lower mounts are coil-over ready for a clean installation. QA1 GM 2.0 Control Arms look incredible and use no unsightly additional adaptors! Form meets function: these newly designed arms look and perform great and don't require painstaking restoring like factory stamped steel control arms.

Designed for the specific needs of Drag-Racing, these control arms are perfect for looking for a bolt-in upgrade to their original suspension or worn and outdated tubular control arms.  Besides improving overall handling, ride quality, and vehicle stance, these arms improve on factory suspension geometry and pave the way for planning additional upgrades like QA1 Pro-Coils and full suspension kits.  (Arms are not compatible with OE springs.  Must be used with a coil-over system.)

• Sold in pairs. Utilize OE-style sway bar links (not included). Includes droop stops on uppers, bump stops on lowers, adjustable steering stops on lowers, and all required mounting hardware.
• High strength, low alloy steel enables optimized thinner wall construction and results in an overall lighter weight.

• GM 2.0 Drag Race Series control arms feature adjustable droop stops to enable the perfect front end rise for optimized launches and ultra-low friction composite bushings for smooth bind-free movement and optimal weight transfer during launch.
