or Transmission tools see the general merchandise section.

Note: These gears are low contact gears (LCG) & will not work in conjunction with the OEM H-D high contact gear (HCG) found in some 1994/1995 and all 1996/Later models. So if you replace a LCG mainshaft gear in a 1994/Later HCG transmission you must also buy a matching LCG gear on the countershaft found in the drive train section.Andrews

The 14mm by 3 3/8 belt is the same that the top fuel racers use on their 600 plus horsepower machines. This kit is designed for oil filter (included) mounting in the motor plate. Kit is the complete drive with outboard bearing supports. The outboard bearing support has one bearing to support the transmission mainshaft. The outboard support plate is reversible. The back side is channeled for another distinct look, but just the flat side will be polished.

eatures:
  • 14mm x 85mm (3 3/8) wide belt, the same belt as used on top fuel Harley-Davidson® race bikes
