QA1 52919 Drag Race Lower Control Arm Kit 67-69 F-Body 68-74 X-Body

The QA1 52919 is a drag race-engineered lower control arm kit designed for serious strip performance on 1967–1969 GM F-Body and 1968–1974 GM X-Body platforms. Built around QA1's "Drag Racing 2.0" architecture, these arms deliver the bind-free suspension movement and optimized weight transfer that competitive drag racers demand at launch.

Key Features:

• Ultra Low Friction Ball Joints — Integrated QA1 low-friction ball joints combined with composite bushings eliminate suspension bind during launch for optimal weight transfer to the rear wheels
• Adjustable Droop Stop — Allows the driver to precisely dial in front-end rise during launch, a critical tuning advantage at the strip
• Billet Aluminum Cross Shafts — Lightweight billet aluminum shafts reduce unsprung front-end weight while maintaining the durability needed for street use
• High-Strength Tubing Construction — The combination of high-strength low alloy steel tubing and billet aluminum cross shafts results in one of the lightest control arm designs available without sacrificing durability
• Robotic Welding & Powder Coat Finish — Robotically welded joints and a high-quality powder coat finish ensure long-term strength and a clean appearance
• Double Shear Lower Mounting — Configured for use with QA1 Pro Coil Systems with a double shear lower mounting design for added rigidity
• Includes Ball Joints and Bushings — Complete kit includes all necessary ball joints and composite bushings for installation

QA1's drag racing lower control arms are proudly manufactured in Lakeville, Minnesota, and are engineered to improve 60-foot times by maximizing front-end lift and promoting consistent, repeatable launches. These arms are also suitable for spirited street driving, making them a versatile upgrade for any performance-minded build.
