CURT Switch Balls

Constructed from premium-grade steel with nickel-chrome plating for long life, CURT Switch Balls are guaranteed for life against defects in manufacturing. The Switch Balls comply with National Standard SAE-J684 and V-5 regulations for conversion ball sets. The exclusive 'J' groove design ensures that with the ball installed on the shank and engaged by a coupler, the hitching system is secure and has been proven safe through independent testing. CURT Manufacturing Switch Balls are designed so that the weight-bearing capacity is resting on the shank, taking the stress away from the ball, freeing the coupler from friction and binding, and providing smoother and safer towing.
