1-7/8-inch ball has up to up to 2,000 lbs capacity and features 3/4РІР‚С– or 1РІР‚С– bolt (shank) diameter.Commonly used hitch ball sizes (diameters) are: 1-7/8РІР‚С–, 2РІР‚С–, and 2-5/16РІР‚С–. Most trailers have a hitch ball size and maximum towing capacity stamped on the tongue, coupler handle, or frame, and you have to choose a trailer ball with the specs that are equal to or exceed those figures. The shank rise (shank height) can be used to precisely level the trailer in case of the improper РІР‚СљriseРІР‚Сњ or РІР‚СљdropРІР‚Сњ of a trailer ball mount.Р”Р‡ull-size vans w/loads requiring weight distributionР”Р‡ull-size trucks w/loads requiring weight distribution.The shank length (distance from top to bottom of a shank): minimum two threads should be visible after the nut is tightened.

The shank diameter (the width of the threaded shank) must be equal to the hole diameter.The hitch ball diameter must be always matched to the trailer coupler size, an undersized ball will loosen up and fail.Rise: The height of the shank can be used to raise a trailer back to level in the event the РІР‚СљriseРІР‚Сњ or РІР‚СљdropРІР‚Сњ of a ball mount is inadequate.

Shanks come in a variety of sizes (5/8РІР‚С–, 3/4РІР‚С–, 1РІР‚С–, and 1 1/4РІР‚С–) and capacities.

Shank Diameter: This is the diameter of the threaded shaft that is inserted through the ball mount.

It is important to use a shank that is long enough to extend beyond the thickness of the draw bar mounting tab to ensure that enough threads are available to securely fasten the ball to the mount.

Shank Length: This is length of shaft that extends beyond the mounting base of the hitch ball.

It is VERY important to match the trailer to the correct hitch ball. In general lighter trailers use smaller hitch balls. Recreational and light commercial hitch balls come in a variety of sizes including 1 7/8РІР‚С–, 2РІР‚С–, 2 5/16РІР‚С– and occasionaly 3РІР‚С–.

Ball Diameter: Check the top of the trailer coupler for the size of the ball diameter required.
