Measurements for Ball Mounts  

Updated 05/12/2026 | Published 05/09/2026

Question:

Trying to find the measurements for multiple hitches. My receiver has less than 5.5 inches of available space from the pin hole to contact with the spare tire. I dont want the hitch sticking out far from the reciever creating a long lever. Im interested in the fastway 2.5inch 18k and 20k adjustable with 6inch along with the b an w 2.5 inch 5inch . Ive got a 2012 f350 with a factory installed receiver.

Hi Cory, can you tell me the specific part numbers and which measurements you want exactly? I only see that you looked at some Trimax HD ball mounts, and I want to make sure I'm getting all of the measurements you're looking for and on the right parts.

BWTS20037B BWTS20040B TMX55QR TMX97QR I think those are the ones im most interested in. Also what exactly is the difference between the last 2?

@Cory not sure which measurements still but the # TMX97QR is the old design where the pin runs behind for adjustment. The # TMX55QR is their updated design where the adjustment holes and pin run through the middle. This allows you to store the ball platform behind it for storage similar to the B&W. Otherwise the specs are the same.
