How to Determine Which Trailer Hitch I Need

Trailer Hitch Guidelines

When purchasing a hitch-mounted product, it is important to know which type of hitch your vehicle has in order to ensure that the product will be a match. The information on this page was designed to help you to determine which type of hitch your vehicle has, what its weight capacity is, and what the inside measurements are.

If the product you are looking at is not compatible with your hitch, our selection of hitch converters* and hitch extenders** can help.

Tongue Weight Capacities for Various Hitch Classes:

Hitch Class Tongue Wt. Capacity
Class I 200-250 lbs
Class II 250-350 lbs
Class III -IV 350-600 lbs
Class V 1,000+ lbs

Tongue Weight Capacity: This is the maximum vertical weight that the frame of your vehicle can support.

Sources for determining tongue weight capacity:

  • Label on the hitch
  • Owner’s manual
  • The installer of the hitch
  • The manufacturer of the hitch

Hitch Sizes: Hitch sizes come in five classes from Class I (light duty) through Class V (heavy duty).

Sources for determining trailer hitch size:

  • Label on the hitch
  • Tape measure
  • Owner’s manual
  • The installer of the hitch
  • The manufacturer of the hitch
Hitch Class Inside Measurements
Class I 1-1/4″ x 1-1/4″
Class II 1-1/4″ x 1-1/4″
Class III – IV 2″ x 2″
Class V 2-1/2″ x 2-1/2″

Note: Some Class I and II hitches may have a 2" x 2" opening

*Hitch Converters: Devices that change the hitch size opening but not the tongue weight capacity.

**Hitch Extenders: Devices designed to increase the distance from the rear of your vehicle to the hitch receiver opening. Hitch extenders place additional stress on the hitch and the frame of the vehicle due to the increased leverage associated with the load being further from the hitch and frame of the vehicle, thus reducing the tongue weight capacity significantly.
