Pre assembled rear 35T gear differential.
New for the Serpent S400 is this innovative 35T rear gear differential. Designed with competition in mind, this new diff is only 5 grams heavier than the standard ball differential yet provides more consistent operation and there is absolutely no slippage, which helps improve acceleration. Another benefit is that it requires little or no maintenance or rebuilding and it can be simply set by just changing the oil. To keep the weight down, the differential is supplied with coated aluminium out drives and to get you on the track as quick as possible, the diff comes pre-assembled, with you only needing to add oil. Expect a front gear differential in the near future.
