Our clutch was shipped in this sturdy wooden box; they are now shipped in heavy-duty cardboard boxes that protect all the components inside from shipping damage. This is very important when dealing with parts that are precision balanced. Included is the clutch alignment tool, pilot bearing, throw-out bearing, flywheel, disc, and pressure plate. If you purchase the Premium package from Monster a new slave cylinder will be included as well. Note the trademark Monster green on the pressure plate.
