Class V adjustable mount trailer hitch dual ball mount is a receiver hitch accessory consisting of 2-trailer hitch balls and a shank. The dual hitch balls eliminate the need to remove and install different hitch balls or ball mounts. The 2 in. hitch ball has a GTW of 10,000 lbs. and the 2-5/16 in. hitch ball has a GTW of 12,500 lbs. The adjustable ball mount allows you to use in the drop or rise position and includes a patent pending hitch U-pin barrel lock and a keyed alike hitch barrel lock. Made of lightweight, rust-proof anodized aluminum that offers superior protection from scratches and abrasions. This ball mount features increased towing capacity for today's towing demands, depending on your requirement. It is ideal for everyday towing, but allows for maximum flexibility when towing multiple trailers and heavy cargo. Class V mounts are great for towing very large campers, large boats and yachts, and trailers carrying commercial construction equipment. Includes a heavy-duty plastic storage and carrying case. (Disclaimer: while these are common uses for this class, it is important that you know the total weight of the trailer and its contents, and that you do not exceed the recommended maximum towing capacity determined by your vehicle manufacturer.).
