Complete gear differential set the X4. Includes updated composite differential situation and target with pulley. Differential gears are produced from tough composite item, precision-molded composite gears coupled with light aluminum hardcoated outdrives, which create a lighter and super-smooth gear differential. The diff case is good for X4 platform and features tiny bleeding holes for the M2.5x8mm screws, to minimize the chance of stripping the diff example whenever tightening reduced the screws. The bleeding holes in addition enable extra oil to empty away. The form through the diff example was updated for an even more focused back belt destination that improves determination & forward traction. The benefit of the apparatus diff is it is actually maintenance-free. Whenever diff is properly built you don't have for maintenance for some time. It's not necessary to change oil frequently, and there is no leakage because of the nice sealing system. The device diff furthermore increases on-power steering that will easily be needed of all kinds of tracks. Functions ideal for both carpet and asphalt tracks. This differential will not be factory pre-assembled.
