Lower Control Arms QA1 52937 64-72 GM A/G-Body

The GM 2.0 Control Arms by QA1 provide increased positive caster compared to OE arms and are among the lightest arms available, featuring lower unsprung weight and improved performance without sacrificing durability.

They include an integrated ball joint design from QA1, which is stronger than OEM, rebuildable for tunability, and ensures long-term reliable service.

These arms feature cross shafts made from billet for reduced weight and durability for the long haul.

Coil-over ready double-sheer lower mounts allow for a clean installation.

The QA1 GM 2.0 Control Arms look incredible and do not use unsightly additional adaptors.

Form meets function: these newly designed arms perform great and do not require painstaking restoring like factory stamped steel control arms.

Designed specifically for the needs of Drag-Racing, these control arms are ideal for those seeking a bolt-in upgrade to their original suspension or worn and outdated tubular control arms.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 enhance 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 and must be used with a coil-over system.

Sold in pairs, they utilize OE-style sway bar links, which are not included.

The package 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, resulting in an overall lighter weight.

QA1's integrated low-maintenance ball joints feature integrated dust boots, are stronger than competing ball joints, provide long-term service, and are rebuildable.

The QA1 GM 2.0 Control Arms will work with either OE or drop spindles.

The increased positive caster design improves straight-line stability.
