Brand new modern springs marked 4.0-5.6 are soft at the beginning of the compression (similar to hardness 4.0) but be harder since the springtime is compressed more at the center, with hardness 5.6 by the end. Pearl-grey color and laser etched for easy recognition. Pair of 2.
Available as some, the springs are separately measured, managed, examined and matched to give identical damping traits. During the selection procedure, each spring is compressed in several fine increments as well as the values are recorded. Each springtime is then matched with another springtime of identical faculties. XRAY goes the excess mile to ensure perfect spring match-ups, giving your car or truck the predictability and persistence you need to help you lead the pack.
