Xray XB2 brass rear lower suspension mounts
Coming from Xray and made for the XB2 2WD off-road buggy are the RF and RR lower suspension mounts machined from heavy brass material. The parts match the standard kit geometry and are usable with the I.S.S. suspension inserts for quick and easy set-up changes. Due to being heavier than the standard alloy parts the hangers improve stability and traction on lower grip surfaces. The mounts are available separately as RF and RR variants.
