XRAY: X4 COMPOSITE GEAR DIFF. CASE WITH 38T PULLEY & COVER

Precision-molded gear differential case with 38T pulley and cover made from tough composite material. Used for #309401 XRAY X4 Gear Differential.

The diff case features small bleeding holes for the M2.5x8mm screws to allow excess oil to drain out. The shape of the diff case has been updated, for a more centered rear belt position that improves consistency & forward traction.
