About This Product
This kickstart clutch gear nut is a specific hardware piece for those running classic 4-speed setups. It is a 5/8-18 x 1/4 x 9/16 hex nut designed to fit 1941 to 1986 4-speed Big Twin models equipped with a kickstart. When you are working inside the transmission or refreshing the kicker assembly, using the correct fastener is vital for proper clearance and torque. This nut is a direct replacement for OEM 7977 and MCS 555706. It is built to factory specifications to ensure a secure fit on the clutch gear, helping you maintain the mechanical integrity of your vintage drivetrain without the guesswork of generic hardware.
Manufacturer part number: 555706.
