QA1 78-88 Gm G-Body Street Performance Front Upper Control Arms

Upgrade your GM suspension with QA1's GM 2.0 Control Arms, offering a superior blend of performance, durability, and aesthetics. These control arms provide increased positive caster compared to OE arms, enhancing straight-line stability for an improved driving experience. Crafted from high-strength, low-alloy steel, these arms feature optimized thinner wall construction, resulting in an overall lighter weight.

The integrated ball joint design is both stronger than OEM and rebuildable for tunability, ensuring long-term reliable service. Billet cross shafts contribute to reduced weight and enhanced durability, making these arms suitable for the long haul. The double-sheer lower mounts are coil-over ready, facilitating a clean installation without the need for additional adapters.

QA1 GM 2.0 Control Arms not only perform exceptionally but also boast a striking appearance, eliminating the need for unsightly additional adapters. Their billet construction offers a sleek look that combines form and function, eliminating the painstaking restoring required for factory stamped steel control arms.

Perfect for GM enthusiasts seeking a simple first step in upgrading their original suspension, these control arms are also ideal for those replacing worn or outdated tubular control arms. They enhance overall handling, ride quality, and vehicle stance, setting the stage for additional upgrades like QA1 Pro-Coils and full suspension kits. Please note that these arms are not compatible with OE springs and must be used with a coil-over system.

Sold in pairs, these control arms come with OE-style sway bar links (not included), bump stops on uppers and lowers, adjustable steering stops on lowers, and all required mounting hardware. The integrated low-maintenance ball joints feature dust boots and are compatible with both OE and drop spindles. The increased positive caster design improves straight-line stability, offering a reliable and high-performing solution.

The GM 2.0 Street Series control arms feature stock length ball joint studs and polyurethane bushings for noise/vibration/harshness isolation. Their durability, coupled with low friction, provides superb handling without undesirable deflection. Compatible with all QA1 single adjustable, double adjustable, and MOD Series Pro Coil-Over style shocks, these control arms boast best-in-class strength in QA1's ball joint housing design.

Lighter than both factory and most aftermarket versions, these control arms are a weight-efficient solution. The uppers weigh less than 7 lbs. per arm, while the lowers weigh less than 9-3/4 lbs. per arm. With a straightforward installation in the OE location, no cutting, fabricating, or welding is required, accommodating both factory and aftermarket disc brakes. Elevate your GM Street, Pro Touring, or Race vehicle with the best-in-class strength and performance of QA1's GM 2.0 Control Arms.
