This clutch assembly replaces the OEM clutch fork and TOB assembly with a bolt-on hydraulic throw out bearing assembly and supplied fasteners. Fitment testing of the hydraulic TOB is required to confirm the proper amount of shims needed for installation and proper clearance.
This 6-speed version comes with the adaptor fitting for the hydraulic TOB to be installed properly.
