QA1 GM Pro Front Coil-Over System - Double Adjustable - 10in 450lbs/in - Select GM 1967-1974 - GD401-10450A

Fits select 1967-1974 Buick, Chevrolet, Oldsmobile, and Pontiac models including Camaro, Firebird, Nova, Ventura, Apollo, and Omega.

The QA1 GM Pro Front Coil-Over System (GD401-10450A) provides professional-grade suspension tuning for classic GM F-Body and X-Body platforms. These double-adjustable shocks feature independent knobs for compression and rebound, allowing you to dial in your ride quality and handling performance for street driving, autocross, or drag racing without removing the shocks from the vehicle.

Constructed with lightweight billet aluminum bodies, these shocks utilize a fully threaded design for up to 2 inches of ride height adjustment to achieve the perfect stance. The system includes American-made high-travel springs with a 450 lbs/in rate, designed with fewer coils and a smaller wire diameter to reduce unsprung weight and maximize travel. The pigtail spring seat configuration ensures a direct bolt-in fit for factory or QA1 tubular control arms.
