QA1 Single 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 single-adjustable valving provides ample range of tunability for comfort and performance.
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 Chevelle, GTO, Cutlass, El Camino among many others. 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.
QA1 single adjustable coilovers deliver exceptional ride quality and performance for your vehicle. With the simple turn of a dial, you can effortlessly switch between a comfortable cruise and a more aggressive feel, making them ideal for daily driving or twisty backroads. 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 Single Adjustable Pro-Coil Kits are eligable 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.
