For example, a 3,500 lb. ball on a 2,000 lb. max trailer weight rated hitch does not increase your towing capacity to 3,500 lbs. Your hitching system is still rated at 2,000 lbs. Conversely, a 2,000 lb. ball on a 3,500 lb. max trailer weight-rated hitch decreases your maximum towing capacity to 2,000 lbs. The hitch ball diameter (A) must be the same diameter as the trailer coupler (1-7/8”, 2”, or 2-5/16”). The shank diameter (B) of the hitch ball should be the same as the hole diameter in the (correct) ball mount you selected. The shank length (C) should be long enough to allow at least two threads to be visible when the hitch ball is installed and the nut completely tightened.
