Weight: 0.56For 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.AndrewsGear 18T Mainshaft 1stFits Big Twin 5 speed all yearsReplaces HD# 35025-79BBy: ANDREWS PRODUCTS INC
