When not in use, these hitches fold under for a clean appearance. The flush fit also keeps the hitch out of the way so you don’t bang your shins. And because it attaches underneath the truck and doesn’t protrude, it won’t affect ground clearance. Not only do these versatile hitches enhance the appearance of your truck, they also adjust to fit different trailer heights without additional mounts. Does that trailer use a 1-7/8", 2" or 2-5/16" ball? Simply pull the lynch pin, swivel to the ball you need and lock it back in place. The Class IV hitch also lets you drop or raise the ball 3-1/2" to fit different trailer heights without changing hitch bars.
