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. 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, Monte Carlo, 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 PERFORMANCE \u0026amp; RIDE COMFORT 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 coil springs built to deliver optimal performance. Spring rates are tailored to your vehicle's weight and driving style.
