QA1 Street Performance Lower Control Arm Kit

Upgrade the front suspension of your classic GM vehicle with QA1's Street Performance Lower Control Arm Kit. This comprehensive kit is designed for a wide array of GM models, including 1970-1981 F-Bodies, 1973-1977 A-Bodies, 1975-1979 X-Bodies, and 1978-1996 B-Bodies. Ideal for drivers seeking improved performance and durability for cruising and everyday driving, these control arms provide a significant enhancement over stock components.

Built for Strength and Longevity

QA1 constructs these lower control arms using high-strength steel tubing, precision robotic welding, and durable billet aluminum cross shafts. This combination results in an assembly that is both exceptionally strong and surprisingly lightweight, contributing to reduced unsprung mass and improved suspension responsiveness. The high-quality powder coat finish not only adds a professional look but also provides excellent protection against corrosion and wear, ensuring a long service life.

Optimized for Enhanced Driving Dynamics

• Polyurethane Bushings: The included polyurethane bushings offer a superior balance between ride comfort and performance. They effectively dampen road vibrations and noise for a smoother ride, while providing the necessary stiffness to maintain precise control during acceleration, braking, and cornering.
• Heavy-Duty Ball Joint: Each kit features a robust, integrated ball joint designed for increased strength and durability compared to OEM parts, ensuring reliable operation and extended service intervals.
• Improved Suspension Geometry: These control arms are engineered to optimize suspension geometry, typically adding 3-4 degrees of caster and 0.5 to 1 degree of additional positive caster. This adjustment significantly enhances straight-line stability, sharpens steering response, and improves tire contact with the road.

The QA1 Street Performance Lower Control Arm Kit is an essential component for anyone looking to enhance the handling, comfort, and overall driving experience of their classic GM car. It's a direct replacement designed for easy installation and maximum performance gains.
