About This Product
This MCS 10-stud clutch hub is a heavy-duty upgrade for your 1941–1984 Big Twin, replacing the original 3-stud design with superior clamping power. Machined from solid steel with ten threaded studs (OEM 37583-41) instead of the shorter 37585-41 pins, it accepts modern clutch packs while retaining stock dimensions for a bolt-in fit. The assembly includes the clutch hub liner (OEM 37549-41) and 8227 brass rivets pre-installed in the outer flange, though occasionally these may arrive separately. Replaces factory numbers 37550-41B and 2472-41. The raw steel finish is ready for your preferred coating or can be run as-is for that traditional race-bike look.
Manufacturer part number: 590131.
