Recommended 5th Wheel Installation Brackets for Base Rails on 2021 GMC Sierra 1500

Question:

I have a 2021 GMC 1500 crew cab PU new. I need the mount brackets for a Reese 5th wheel hitch. I already have the rails. Do you have what I need to go under my bed to mount on my frame and bolt kit? Yes my bed is a 6.5 foot bed. Thanks

If you just need the installation brackets for your 2021 GMC Sierra 1500 with 6-1/2 foot bed you can use the Reese Quick-Install Custom Outboard Brackets for 5th Wheel Trailer Hitches # RP56015. These are custom installation brackets so your drilling will be minimal, if any is required.

The complete kit with base rails and brackets is available with the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP56015-53.

I've linked a review video of these parts for you to check out.
