The XRAY 355049 Center Differential Spur Gear is a precisely machined 47-tooth cog built to deliver dependable engagement and reduced wear under load. It is a go-to upgrade for racers and weekend builders aiming for steadier drivetrain behavior. The unit's 50 mm diameter requires the Center Diff Shimming Plates (#354032) and the Aluminum Center Diff Mounting Plate 7075 T6 (3mm) (#354055) for correct fitment; the 48 mm XB9 variant does not require these parts.
