QA1 GM Pro Front Coil-Over System - Double Adj. - 9in x 650lbs/in - Pigtail Large - Aluminum

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.
