Are designed for top performance and safety, constructed from premium grade steel with a nickel chrome long-life plating. The J-groove design ensures that when the ball installed on the shank is engaged by a coupler, the hitching system remains secure. No pins or tools are required, simply slide down over and up, then twist!
The Curt Switch Ball™ features a J-groove design to slide 1-7/8", 2" and 2-5/16" trailer balls, down, over, and up, then twist, without the need for pins or tools. Each Switch Ball™ meets the V-5 and SAE-J684 regulations for conversion ball sets and is designed so the weight bearing capacity is resting directly on the shank. This feature takes stress away from the ball and frees the coupler from friction and binding, to provide smooth and safe towing. Curt Switch Ball™ is guaranteed for life against defects in manufacturing and is constructed from premium grade steel with a nickel chrome plating.

I have had this interchangeable ball hitch for over 16years. It has with stood the test of time. It is easy and simple to use. I have had no problems with it. Once the trailor is put onto it; it is impossible for the ball to come off. I purchased the 8000lb two ball set. This is the most used sizes for trailers. Cons. The chrome will come off over time. To help this from happening use grease to lube up the ball.
