PN Racing V4 Enclosed Mod0.5 Ceramic Ball Diff Set
Mini-Z option parts manufacturer PN Racing has introduced this V4 Enclosed Mod0.5 Ceramic Ball Diff Set. Dropping directly in the Stock Mini-Z Gearbox of the MR03/04, the new enclosed case reduces dust and particles from entering the diff internals resulting in less maintenance. The latest set now includes Machine Cut Delrin Limited Slip Mod0.5 Spur Gear which allow normal and limited slip diff action.
