This is a complete five-finger clutch hub assembly for all Big Twins (except diaphragm clutch) from 1936-early 1984. The five finger style uses 5 long studs, provides more even adjustment, greater support and less plate wobble than the late-style 3 short stud hub. Assembled hub is complete with studs and nuts, friction disc with rivets, bearing retainer with bearings, bearing retainer plate and special five-finger pressure plate.
