Not all styles are available for all models and usually there is a default style for a particular model wincher. Please speak with your sales representative if you have questions about this or want something custom.
The Bumper Only is just that. A heavy duty replacement bumper. It has no capability to mount a winch.
The Winch style is designed to mount a winch, like in the picture below.
The Receiver style, rather than having a winch mount, is equipped with a 2″ ID receiver tube identical to what you would find on a trailer hitch. It’s useful for portable, cradle mounted winches and many other functions.
By definition the Grill Guard is the center piece of a brush guard assembly, the piece positioned in front of the grill of the truck while the Light Guards are the outer tubes that protect the headlight and the corners of the truck. The grill guard is available in several styles.
