This is a replacement XRAY 69mm 5-Dot Front Shock Spring Set. These progressive springs are slightly progressive, but under more compression they change characteristics to become more linear. This gives an excellent feeling and feedback in all different track conditions. Marked with FIVE dots for easy identification.
Available as a pair, the springs are individually measured, controlled, inspected and matched to provide identical damping characteristics. During the selection process, each spring is compressed in several fine increments and the values recorded, and then each spring is matched with another spring of identical characteristics. XRAY goes the extra mile to ensure perfect spring matches, giving your car the predictability and consistency that you need to help you lead the pack.
