How to determine the Hitch Size for Hitch locks

Expert Reply:

To determine the size of the Receiver lock you will need you need to determine the size (see link below) of the receiver on your vehicle and you also need to measure the overall width of the outside of the receiver at the hitch pin hole. If you have a class I or class II receiver you will need a 1-1/4 inch receiver lock and if you have a class III receiver or larger you will need a 2 inch receiver, then you need to make sure the inside width of the receiver lock is at least as wide as the overall width measurement of the hitch at the hitch pin hole.
I have posted links to some of our most popular hitch locks we carry for the 1-1/4 and 2 inch hitches.
