This is an optional Pair of XRAY Rear Shock Spring Set (C=0.50/4-Dots)
New optional REAR linear springs are recommended for high-traction tracks. The springs have been specifically designed to complement the big-bore shocks. Linear spring rate is constant throughout the entire compression. Marked with FOUR DOTS for easy identification.
The springs, like all the other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.
