How to Measure Hitch Bike Rack Sizes to Determine Which Hitch is Needed
Updated 08/12/2010 | Published 08/10/2010
Question:
this may sound dumb-but how do you measure the size of the rack? 1 1/4 - 2in
asked by: janet
Expert Reply:
The 1-1/4 and 2 inch sizes you see refer to the hitch receiver opening. If you have the rack, measure the shank at the bottom of the rack. If it measures 2 X 2 inches, then you will need a Class III or higher 2 inch receiver.
If it measures 1-1/4 X 1-1/4 inches, you will need to determine whether or not it will fit a Class I or Class II hitch. There are stops welded inside Class I hitches to prevent use of Class II accessories that can overload a Class I hitch.
I have added a link below to some FAQ articles on hitch sizes and classes that should answer most of your questions and clear up a lot of confusion.
If you write back with the bike rack you have or are interested in as well as the hitch or vehicle you will be using, I can help you sift the bike rack fits.
