Before you choose an adjustable hitch or adjustable ball mount from Curt, B&W, Reese, Andersen, Trimax or any one of our top-quality brands there are some things to consider first. The weight of the trailer and its load, the height of your receiver and the size of the hitch receiver's opening. Among your adjustable hitch choices, you will see aluminum, stainless steel, and steel adjustable ball mounts. If you are towing a variety of trailers there are adjustable hitch ball mounts that have two or even three different ball sizes. Fleet operators consider keeping a few adjustable hitches on hand to move from truck to truck.
