Diversi-Tech is famed for the quality of its American made, aircraft grade aluminum drop hitches and its unique trailer coupler locks. Diversi-Tech hitch ball mount products are CNC machined from solid aluminum billet so there are no welds or weak points. In fact, Diversi-Tech hitch ball mounts are so strong that they are only limited by the structural integrity of the balls mounted to them. Diversitech hitch balls are finished in beautiful chrome plating for a finish that will last longer than raw aluminum or zinc plated balls. Diversi-Tech products are unique because they are available with a "self-locking" feature found on no other hitch mount product. On "self locking" models, barrel locks operate o-ring sealed pins for the ultimate in security and smooth flawless operation, no separate pins with retaining clips necessary.
