Part #: GD507-09650D

QA1's GM Pro Coil Systems are available for 1963-1982 Corvettes and for 1958-1970 Full Size Chevrolet vehicles, including Impalas, Bel Airs and Caprices. They are the perfect option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling. Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance. Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications. Adjustable Pro Coil System Features:, Available in independent compression and rebound double adjustable, simultaneous compression and rebound adjustable, or drag "R" Series adjustable, Lightweight Billet Aluminum Coil-Over Shocks, High Travel Springs, Easy, Bolt-In Installation, Ride Height Adjustable, 100% Dyno Tested and Serialized, Serviceable and Rebuildable by QA1 Authorized Service Centers, Made in the USA, Used in drag racing, street performance, autocross, road racing and street rod applications, Sold in Pairs.

MIA's Description

QA1 Double Adjustable Pro-Coil kits are an excellent choice for any GM muscle car owner looking for a better stance, ride quality and performance. These easy-to-install bolt-in kits are a great solution for adjustable ride height, and the double adjustable valving provides ample range of tunability from the street to the track. GM Pro-Coil kits offer 0 to –2 inches of ride height adjustability, allowing you to dial in the perfect stance for your Corvette, Impala, Bel Air and others. Adjustments within this range can be made with a simple turn of the spring seat nut. Double-adjustable coilovers are ideal for drivers looking for great performance on the street or track. Independent tuning of compression and rebound allows you to fine-tune the handling or straight-line performance of your vehicle for any driving condition. Accessing the 18-position knob is easy, and by turning the steering wheel to full lock, you can reach in and make your tuning adjustments at the base of the shock. QA1 Pro-Coil kits feature high-travel, USA-made coil springs built to deliver optimal performance. Spring rates are tailored to your vehicle's weight and driving style. GM Pro-Coil Kits seamlessly bolt-in with both Original Equipment (OE) stamped steel control arms or QA1 tubular control arms. QA1 shocks are proudly made in Lakeville, Minnesota. Eligible for a Limited Lifetime Warranty.
