Curt 45310 Class 4 Ball Mount - 2" Drop / 1" Rise, 10,000 lb

Why Choose the Curt 45310 Class 4 Ball Mount?

The Curt 45310 is a heavy-duty Class 4 ball mount designed for demanding towing applications with standard 2-inch receiver hitches. Its reversible design provides either a 2-inch drop or 1-inch rise to help level the trailer with the tow vehicle.

The hollow carbon-steel shank reduces unnecessary weight and can be used with a compatible anti-rattle hitch pin or lock. A gloss black powder-coat finish helps protect the mount against rust, scratches, and UV exposure.
