Info & Terms

The Hitch is the mechanism that is typically mounted to the rear of a vehicle under the bumper. There are five classes of Hitches for towing trailers. Each class is designed for a specific trailer weight range. When selecting the appropriate hitch, make sure the weight rating of the hitch is greater than the loaded weight of the trailer that will be towed. The tow vehicle capacity for weight carrying and hitch attachment will vary and will sometimes dictate the class of hitch that can be used. As you will see below, under each class, always consult your owner's manual for vehicle rating.

Class I
Class I hitches are weight-carrying (WC) hitches rated up to 2000 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 200 lbs. This style of hitch typically uses a 1-1/4" square receiver opening. The use of a draw bar and hitch ball of the same rating or higher is required. Some hitches in this class may attach to the vehicle bumper or trunk pan. Most other Class I hitches attach to the vehicle frame. Always consult your owner's manual for vehicle rating.

Class II
Class II hitches are weight-carrying (WC) hitches rated up to 3500 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 300 lbs.
