This is an optional Serpent V2 Differential Gear Set, and is intended for use with the Serpent 811 line of 1/8 scale vehicles. This gear set is an updated set making differential action smoother with an improved gear mesh and tooth shape. This updated design no longer uses the backing shim on the 10 tooth spider gears used on the original differentials. This makes assembly and maintenance easier with less parts to work with.
Note: Serpent testing has determined that you will need to use 2,000 cst heavier oil than before to achieve the same results.
