When choosing the right winch , you will need to know several things: the intended use, capabilities, and cost. Determine your vehicles capabilities for weight, location of the winch when mounted, and correct alignment. Start by getting your vehicles gross weight multiply it by 1.5. This will give you the minimum capacity. The gross weight is normally on a sticker inside the door jamb or under the hood and you may find it in your owners manual. Most winch makers will advise you to use a line pull rating of 12% to 15% greater than your gross vehicle weight. Find a winch that suits your needs for the actual load you need to move.
