Question:
I just got a 2026 GMC Sierra 2500. I already have a BandW Patriot 18k sliding hitch that I took out of my 2017 Silverado 1500. What Im needing is the mounting bracket and rails so I can install them in the 2026 GMC. Thank you

Hey Ryan, congrats on the new truck! To add a set of 5th wheel rails to your new 2026 GMC Sierra 2500 you'll need the following parts:
Base Rails for 5th Wheel Trailer Hitches item # BWRVR3210
Custom Mounting Brackets for Above Bed Base Rails item # BWRVR2505
The item # BWRVR2505 brackets are custom fit and will install in preexisting holes in your Sierra's frame. The hardware included will attach the brackets to the item # BWRVR3210 rails inside your bed. Your Patriot Slider item # BWRVK3270 will attach directly to them.
What kind of 5th wheel trailer are you towing and do you have any trips planned with your new truck?
