47-tooth big external spur gear for center differential, precision-machined on an exceptional gear machine. May be used with Center Diff Shimming Plates (#354032) and Aluminum Center Diff Mounting Plate 7075 T6 (3mm) (#354055) due to bigger diameter (50 mm).
Note:
while utilising the more recent as a type of 47T spur gear (with 48 mm diameter) on XB9, the extra components (#354032 and #354055) don't need to be properly used.
