This is an optional XRAY Progressive Spring Set, and is intended for use on the front and rear of the XRAY XB9 and XB808 1/8 scale buggies. These springs provide improved steering at the beginning of the corner, but will help to resist rolling in the middle of the corner as the spring becomes stiffer and are recommended for medium to high traction surfaces. These progressive rate springs are soft at the beginning of the compression, but become harder as the spring is compressed through the stroke.

Available as a pair, these XRAY 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 are recorded. Each spring is then matched with another spring of identical characteristics. These springs have three stripes on one end identifying their rating.
