The Curt Switch Ball is a trailer ball that provides different ball sizes on the same shank. Similar to Curt multi-ball and multipurpose ball mounts, the Switch Ball is designed to make towing easier.
Instead of having multiple trailer balls attached to a ball mount shank, the Switch Ball is a single trailer ball shank that attaches to a regular ball mount and allows for different trailer ball diameters to be used on the shank. The trailer ball design features a groove, shaped like a “J”, cut into the shank. With a simple press of your hand and a twist, the special trailer ball can be installed and is immediately ready for towing.
The Switch Ball requires no tools and no pins for switching ball sizes. Because of the J-shaped groove, the trailer ball stays firmly attached to the shank and securely engaged to the trailer coupler during travel. The Switch Ball is designed so that the weight of the coupler and trailer is resting on the shank, taking stress off the trailer ball itself and freeing the coupler from friction and binding. This provides an overall safer ride and smoother towing.
