Curt Q25 5th Wheel Trailer Hitch w/ R24 Slider for 2021 GMC Sierra 2500 with Above Bed Rails


I want to swapout my Pullrite fithwheel hitch for a Curt Q25 w/R24 slider. I have above bed rail system. Do I need to change the rails or will the new hitch fit on current rails. Pickup a 2021 GMC Seirra 2500


Expert Reply:

The Curt Q25 5th Wheel Trailer Hitch w/ R24 Slider, # C16566 mounts to ISR (Industry Standard Rails) pattern above bed rails. If you are installing this in a 2021 model year GMC Sierra 2500, it most certainly will have these rails. You are good-to-go with the rails you have. Simply select the link for the # C16566 product page and proceed to checkout. Happy Travels!

FYI, the Curt 10" Fifth Wheel Trailer Hitch Lube Plate, # 16721 is the correct part number for the Curt Q25.
