Bolt On Universal Hitch for a 2021 GMC Sierra 3500HD w/ Wider Frame Rails

Question:

Im looking for a hitch that will bolt onto a 2021 GMC Sierra 3500HD that has wider than standard frame rails. Hole width on center is 39 and I need a 7.5 from the frame to clear the customer bed that is on it.

I have a solution for you but with that wide of a frame you will not be able to use any of the custom fit hitches that are available for the varying models of GM 3500 trucks. The Draw-Tite Ultra Frame Service Body Trailer Hitch Receiver item # 41990-16 is going to be your best option for attaching a hitch to your 2021 GMC Sierra 3500HD that has wider than standard frame rails. I have attached the instructions to show the options and steps that needed to be taken to bolt this hitch to your truck. This hitch has 16" mounting brackets.

I have attached a diagram of the mounting brackets that come with this hitch.
