Question:

Hello, I have a 2025 F350 Lariat long bed. It did not come with the 5th wheel prep package. The OEM part PC3Z5F057A has been out of stock for sometime. Do you guys sell a part that will put the Ford 5th wheel pucks in? Thanks

We have exactly what you need, Don! The Reese underbed puck system is exactly what Ford would have put in you 2025 F-350 from the factory.

There is an additional part needed depending on if you have the factory welded inner frame brackets or not. I included a picture of what these look like to make identifying that part easier.

With: Under-Bed Rail Kit RP37KR
5th Wheel Rail Adapter # RP47KR

Without: Under-Bed Rail Kit # RP37KR
5th Wheel Rail Adapter # RP47KR
Inner Frame Brackets # RP97KR

Please note that we are these are currently 3 weeks out (as of 04/17/2025). The under-bed kit (RP37KR) will need to be ordered with our Customer Service over the phone at 1-800-298-8924.

Do you have a trip planned and do you have the hitch already?

Thanks, I did typo, this is a 2024, not 2025, F350. It does look like it has the factory welded brackets. I took a picture here - https://photos.app.goo.gl/qrA8PTpsu2vdApQL6 I couldn't find the part RP37KR, so I guess I have to call like you said. I do see the RP67KR but I am not sure what the difference is? So I need RP37KR and RP47KR only. I think? I would like a new hitch, my old one is for in the bed rails and I want to be able to remove completely and only leave behind the pucks. I still have my old truck with a hitch so I can use that until I get the new truck ready.

@Don Good catch! The # RP67KR includes the underbed puck system and the rail adapter you need (don't know why I couldn't find that when I answered your first question). I looked at your picture and you definitely have the welded frame brackets already, so no need for the extra part. We absolutely have a hitch for you, but a little more info might help me narrow down a suitable recommendation (weight, type of pin box, stuff like that). My personal favorite is B&W, like the 25k # BWRVK3305, as it is American made and all their stuff is built to last. This will also drop right onto the underbed system, so you will have a clear bed when you take it out. Let me know your camper info and I can get you all squared away. : )
