Industry Standard Rails for a 2021 GMC Sierra 2500 to Mount a 5th Wheel Hitch
Question:
I have a hitch for the bed of my 2021 GMC AT4 2500 but do not have rails. Do you have a mounting system to secure the hitch to the bed of my truck? Thank you for your help!

I do have an option for you as long as the hitch that you have attaches using industry standard rails. The Curt Custom Fifth Wheel Installation Kit for Chevy/GMC Truck # C16429-204 is a confirmed fit for the 2021 GMC Sierra 2500 without a factory prep package (puck system in bed). These rails are made in the USA and are custom for your truck to mount to existing holes in your GMC Sierra 2500's frame. This will provide you with a set of industry standard rails that you can then attach your 5th wheel hitch to.
If you want to make hooking up your 5th wheels wiring easier, I recommend the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C53CR. This will allow you to move a 7-way connector into the bed of your truck while retaining use of the factory 7-way at the rear of your truck.
