Hey Nate, thanks for reaching out. We do have a 5th wheel rail kit for your 2021 GMC 2500, but the # C16411-104 kit you mentioned is not correct. That is for the 2011-2019 models, so that will not fit your 2021. Instead, you will need the following:
- Curt Custom Fifth Wheel Installation Kit for Chevy/GMC Truck - Gloss Finish # C16429-104
This is a full kit so you get your rails, custom brackets and all necessary hardware. The rails are industry standard so they will work with virtually any 5th wheel hitch made for standard rails.
What kind of 5th wheel hitch do you have, and what camper are you hauling?

Also do you recommend using and blue lock tight on the threads?

Hello Nate, I have a 2021 Chevy Silverado 2500 HD. I purchased this rail mount kit. Flawless installation! I will admit I was a bit nervous drilling thru my truck bed. The install instructions were clear and precise. I watched a few YouTube videos before I started. Took about 2 hrs. Hope this helps! Etrailer is a premium retailer! Best of luck! Chuck
