QA1 Street Performance Upper Control Arm Kit

Enhance the front-end performance of your classic GM vehicle with QA1's Street Performance Upper Control Arm Kit. This kit is engineered for a wide range of popular GM platforms, including 1970-1981 F-Bodies, 1973-1977 A-Bodies, 1975-1979 X-Bodies, and 1978-1996 B-Bodies. Designed for drivers who prioritize a comfortable yet capable ride for cruising and daily use, these control arms offer a substantial upgrade over factory components.

Engineered for Performance and Durability

QA1 utilizes high-strength steel tubing and precision robotic welding to construct these robust control arms. The integration of billet aluminum cross shafts results in a lightweight yet incredibly strong assembly. This design not only improves durability but also contributes to reduced unsprung weight, benefiting overall handling dynamics. The durable, high-quality powder coating ensures a long-lasting, attractive finish that resists corrosion.

Optimized for Ride Comfort and Handling

• Polyurethane Bushings: These bushings provide excellent vibration isolation, reducing road noise and harshness for a smoother ride, while still offering sufficient stiffness for responsive handling.
• Integrated Ball Joint: A heavy-duty, integrated ball joint is included, offering superior strength and longevity compared to stock ball joints.
• Caster/Camber Adjustment: The arms are designed to provide beneficial geometry changes, typically adding 3-4 degrees of caster and 0.5 to 1 degree of additional positive caster, which improves straight-line stability and steering feel.

This QA1 Upper Control Arm Kit is the perfect solution for restoring or upgrading the front suspension of your classic GM muscle car or sedan. Experience improved handling, a more comfortable ride, and enhanced durability.
