Description

Upgrade your rear end with QA1's Pro-Rear System. Available in the MOD series, this kit offers double adjustable, single adjustable, and ride-sensitive valving non-adjustable options. Each adjustment has been carefully defined to provide the ideal horse curve to maximize performance, with evenly spaced valving changes throughout the adjustment range, ensuring no jumps when adjusting between any two clicks. These Pro-Rear Systems are commonly used in drag racing, street performance, and street rod applications. Features lightweight aluminum construction, rear coil springs included, and a gas-charged design. The system allows for a suspension height adjustment of 0.0-1.5 inches lowered.
