If you own multiple trailers or frequently tow a variety of loads, you know how much time and money are spent tailoring your towing system to each and every individual trailer. There is nothing more inconvenient than switching back and forth between a few different ball mounts and trying to remember which mount fits with which trailer. A CURT adjustable ball mount is your multipurpose towing solution. The CURT slim adjustable channel-style ball mount provides a weight capacity of up to 10,000 pounds and only weighs 15 pounds. It has a shank size of 2 inches x 2 inches and features two different trailer ball sizes to accommodate two different coupler sizes: 2-inch and 2-5/16-inch. It also features an adjustable shank assembly with multiple mounting holes for varying ball heights. Each trailer ball can be raised to a maximum of 3-1/2-inch rise or lowered to a maximum of 3-3/4-inch drop, allowing you to make your trailer completely level in any towing situation. The CURT slim adjustable ballmount offers a gross trailer weight capacity of up to 8,000 pounds for the 2-inch ball and 10,000 pounds for the 2-5/16-inch ball. It allows you to tow a variety of trailers, and it features two pin holes in the shank to be mounted at an 10-inch or 11-inch length. All CURT channel-style adjustable hitches are made with sturdy steel construction and come with a black carbide powder coat finish for long-lasting rust, scratch and UV resistance.
