We Know: How to Buy a Trailer Hitch
About Trailer Hitches
There are two kinds of trailer hitches. One is weight distributing, and the other is
weight carrying. When choosing a trailer hitch, be sure that it will work with the kind of
trailer you will be towing.
When manufacturers or retailers reference GTW, it stands for Gross Trailer Weight. TW means
Tongue Weight.
Gross Vehicle Weight Rating (GVWR)
The weight rating is as follows, broken down into classes:
- Class 1: GVWR to 2000 lbs.
- Class 2: GVWR to 3500 lbs.
- Class 3: GVWR to 5000 lbs.
- Class 4: GVWR plus 5000 lbs.
How does a trailer hitch work?
A trailer hitch connects the towing vehicle to the trailer. The trailer has a socket which
fits over the trailer hitch ball. Once the socket is in place, it is locked down. The socket
and ball must be the same size and that is dependant on the trailer's class. Most people will
permanently install the hitch onto the towing vehicle.
Types of Trailer Hitches
The following are the different types of trailer hitches available:
- Receiver hitch: Uses a ball mount, or ball platform and can be removed when not in use.
Comes in two sizes, 2" and 1 1/4". Some choose to install receiver hitches on the front of their
vehicle for mounting a winch, bike racks. Receiver hitches can be used for weight carrying or for
weight distribution if a weight distribution system is used with a class III or IV receiver style
hitch.
- Fifth wheel or gooseneck hitch: These are mounted through a truck bed to the vehicle
frame or to brackets.
- Frame or bumper hitch: Often used for light towing but can interfere with the protection
offered by the vehicle's bumper. Not recommended by most car manufacturers.
- Weight distributing hitch: Mainly used for heavy trailers, they are designed to increase
brake and steering control.
- Weight carrying hitch: Attaches to the vehicle frame and connects to the trailer. Best
when towing small to medium sized loads.
