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. DIAL IN THE PERFECT STANCE 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. TUNE YOUR RIDE COMFORT \u0026amp; PERFORMANCE 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.
