Fits select 1963-1987 Chevrolet C10, C10 Pickup, C10 Panel, and C10 Suburban models.

The QA1 Front Coil-Over Conversion Kit (MPN 52611-S850) provides a comprehensive suspension overhaul for classic Chevy trucks, replacing dated factory components with modern, adjustable geometry. This bolt-in system is engineered to improve handling and stance without the need for a full chassis swap. By combining tubular upper and lower control arms with single-adjustable coil-overs, this kit allows for precise tuning of both ride height and damping characteristics.

This kit features high-travel 850 lbs/in springs and shocks with single-adjustable valving, allowing you to dial in the rebound and compression simultaneously to suit your driving style. The included tubular control arms are designed with performance-enhancing geometry, providing up to 7 degrees of increased caster for significantly improved high-speed stability and steering feel. When paired with popular drop spindles, this system can achieve up to a 5-inch total drop.
