While we do have a base rail and bracket kit that fits your 2021 Ram 3500 with an 8 foot long bed, the parts you mentioned won't fit as they are for certain Ford trucks. So instead, the base rail and custom brackets that will fit your 2021 Ram 3500 are the following:

- Reese Quick-Install Custom Installation Kit with Base Rails # RP50085-58

I verified with the manufacturer, Reese, that these do in fact fit your 2021 Ram 3500, and are the best option because they do not require any drilling into your frame rails to install. Not having to drill is not only great for your truck but will benefit you whether you are doing the install yourself (saving hours) or having a professional do it (less install time equals less expensive labor costs).

These will allow you to use any 5th wheel hitch that mounts in above-bed base rails, like the outstanding Curt A20 # C16140 or Reese M5 # RP30928.

The only other thing you will need if you don't have one is a 5th wheel wiring harness, with the correct fit for your 2021 Ram 3500 being the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070.
