To find your hitch system rating, start by examining the three trailer hitch components:
The hitch
The ball mount
The trailer ball
Each component is rated for the amount of weight it can haul. The lowest rating of the three components determines the overall rating of your total hitch system. For example, if you have a 3,500 lb. hitch and ball mount with a 2,000 lb. trailer ball, your hitch system is limited to the 2,000 lb. trailer ball towing capacity.
