XRAY 308372 - PROgESSive Spring-set C = 2.2-2.6 (2)   [XR-308372]

New progressive springs marked 2.2–2.6 are soft at the start of the compression (similar to hardness 2.2) but be harder while the springtime is compressed more at the center, with hardness 2.6 by the end. Black color and laser engraved for simple identification. Pair of 2.

Available as a pair, the springs are independently calculated, managed, inspected and matched to give identical damping traits. Through the selection process, each springtime is compressed in a number of fine increments while the values are recorded. Each springtime is then matched with another spring of identical traits. XRAY goes the additional mile to make certain perfect spring match-ups, offering your vehicle the predictability and persistence that you need to assist you to lead the pack.
