OEM replacement 9-plate clutch stack, pre-measured to a height of 1.960″, fits Big Dog models from 2005-2010. Replacement clutch stack can be used as a direct replacement for both existing 9-plate and 12-plate clutch configurations. If switching from a 12-plate stack to a 9-plate stack, you must also update the inner and outer ball and ramp assembly located in the pulley cover, for more information, please contact the BAKER Drivetrain tech department.
