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.
Achieving the perfect, level stance is critical for the overall look and appearance of your car. GM Pro-Coil kits offer 0 to –2 inches of ride height adjustability, allowing you to dial in the perfect stance for your Camaro, Firebird, or Nova. Adjustments within this range can be made with a simple turn of the spring seat nut. For an additional drop beyond 2 inches, consider adding drop spindles to your car.
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. Need help choosing the correct spring rate? Watch this video!
GM Pro-Coil Kits seamlessly bolt-in with both Original Equipment (OE) stamped steel control arms or QA1 tubular control arms. This gives you the flexibility to use the kit with your existing setup or upgrade your control arms for additional performance gains.
QA1 shocks are proudly made in Lakeville, Minnesota. See a complete video on the manufacturing process.
QA1 Double Adjustable Pro-Coil Kits are eligible for a Limited Lifetime Warranty. For peace of mind, simply register your shocks at QA1.net/Warranty to ensure coverage for as long as you own your vehicle.
