A great tuning option from Team Xray is this new ball diff to suit their XB4 and XB4 2WD models. Compared to a gear diff, this ball version increases traction and is recommended for low-traction tracks. The complete factory pre-assembled ball differential features Hudy Spring Steel diff outdrives and screw for external adjustment, tough composite crown gear, high-performance bearings, a carbide axial thrust bearing, heavy-duty diff washers and ceramic 2.4mm diff balls.
