No, you do not need a mounting system. However, because hoist brackets are sized differently on vehicles, you may need a mounting ring for a more secure fit. There are instances where full size trucks need a large ring because their hoist bracket is larger than the mounting surface.
Most customers do not require a mounting ring but may choose one anyway because it will create metal on metal contact, instead of metal on plastic contact. Again, in most cases a ring is not necessary but just better.
