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 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. 1 Year Warranty QA1 warrants that the products will be free from defects in material and workmanship for one year from date of sale to the original purchaser.

Runs EXTREMELY small
Color: Black-satin, Size: 3X-Large
Ordered a 3X but got a XS…i am a 42-44, got the 3X to have tapered to my fit, but upon opening the pants, it seemed they may be more of a 32-34 and the adjustable straps aren’t really adjustable, they are just buckles sewed in place for design. The 3X tag sewn in is a complete lie! Only giving 1 star because they did have the satin tuxedo stripe on the side!
