Improve the rear suspension of your Malibu, Monte Carlo, Cutlass, and other G-body GMs with QA1's bolt-in rear coilover conversion kit. These kits are an excellent choice for any G-body owner looking for a better stance, ride quality and performance. This kit includes specially designed mounting brackets, adjustable aluminum shocks, springs, and all necessary hardware.

DIAL IN THE PERFECT STANCE

We understand that achieving the perfect stance for your car can be a challenge. That's why we've created a solution that makes it easy to adjust your ride height. QA1 coilovers feature a fully threaded, aluminum body and adjustable brackets which allow you to achieve 1” higher than stock down to 3" lower than stock ride height.

COMFORT & PERFORMANCE  

Fine-tune your suspension for optimal performance on the street or track with our double-adjustable shocks. Independent tunability for rebound and compression allows you to dial in your suspension for any driving condition. Each knob has 18-clicks of adjustment. Perfect for performance cars and drivers who demand the best in ride quality and handling.
