There are five classes of tow hitches for towing trailers. Each class is designed for a specific trailer weight range. The information below is pretty technical, so get a cup of coffee before starting and read carefully.

When selecting the appropriate tow hitch make sure the weight rating of the trailer 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.

CLASS I TRAILER HITCHES

Class I tow 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.

• A Class I hitch usually has a 1-1/4" square receiver opening.
• A higher class drawbar does not increase the towing capacity of the hitch.
• Class I hitches usually attach to the bumper, truck pan or vehicle frame.

CLASS II TRAILER HITCHES

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.

• A Class II tow hitch usually has a 1-1/4" square receiver opening.
• A higher class drawbar does not increase the towing capacity of the hitch.
• Class II hitches usually attach to the bumper or vehicle frame.

CLASS III TRAILER HITCHES

• Class III hitches are weight carrying (WC) and also are weight distributing (WD) depending on the vehicle and hitch specifications.
