XRAY Rear Shock Spring Set (C=0.50/4-Dots) (2)
This is an optional XRAY 4-Dot Rear Shock Spring Set. These springs are harder than the 0.40 2-dot springs included with the XB4 2WD.
These XRAY Premium shock springs are designed specifically for big bore shocks. They have been manually measured, selected and matched into pairs to guarantee equal length and damping characteristics. The springs then receive a laser engraving for easy identification.
