Xray 368285 REAR SPRING-SET C=0.40 - 2 DOTS (2) (XB4)
The XB4 springs have been specifically designed to complement the big bore shocks.
The springs, like all the other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.
The spring rate is constant during the entire spring compression. There are springs with different spring rates available as optional tuning parts.
