Product Overview
QA1's Heavy Duty Pro Rear Systems are the perfect solution to add coilovers to your car or truck. Designed for any vehicle with a 1700-2600 lbs. rear axle weight, this kit includes all the necessary hardware and bracketry for a seamless installation. With double shear bracketry and increased spring rates, it ensures the strength and support you need for street and race applications. This simple weld-on kit features axle mount bracketry, upper shock mounts and tubing, and fully adjustable QA1 coilover shocks and springs.
Ride Height Adjustability
Our axle-mounted brackets offer ¾” increments of adjustment, and the coilover shock allows for fine-tuning. Combined, you will have a total of 9” of ride height adjustability, giving you full control for your desired stance.
MOD Series Coil-Overs
Designed for top builds wanting more tunability and aggressive force curves, these shocks feature modular valve packs, allowing valving changes without removing them from the car. With high-speed and low-speed bleed adjustability, these shocks are both streetable and able to get high-horsepower cars down the drag strip.
Easy, Weld-In Installation
Each kit comes complete with the essential brackets, tabs, and hardware, making it a simple weld-on solution to get the job done efficiently without excess fabrication or trips to the parts store.
