5TH Wheel Bed Rails and In Bed Wiring For a 2017 GMC Sierra 2500HD  


I’m looking to install a set of 5th wheel bed rails in my truck 2017 gmc sierra 2500hd I don’t think I have the prep package as I don’t have holes in my bed. The frame is threaded on each side for the rail adapters is there a specific kit I need? Thanks

If you are looking for the industry standard rails the Curt # C16411-204 includes the above bed rails and below bed mounting brackets. If you prefer a system closer to the factory install for a cleaner bed the Reese # RP30158-68 provides you with the 4 outer puck holes for using a 5th wheel hitch as well as the center gooseneck hole. The 4 outer holes are the same dimensions as that used on the Ford Puck system so you can use either the Fixed # BWRVK3300 or Slider # BWRVK3370 5th wheel hitches.

The Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157 will give you a 7-way connector inside your bed so you will not have to stretch the trailer connector across your tailgate and down to bumper connector.
