Serpent introduce a gear differential for their Spyder SRX-2 line of vehicles including the mid and rear motor buggy as well as the upcoming short course truck. The diff features a compact composite material housing and it is of a multi-piece design with a separate diff gear and two side plates that are held in place using small screws and metal backplates for improved fitment and leak-free mounting. The internal gears are made from sintered metal while the crosspins are made from lightweight aluminium. In combination with the lightweight spring steel outdrives the differential weights in at only 28.9g without oil. The diff is usable instead of the standard ball diff and comes in handy especially on high grip surfaces.
