Mounting Brackets Needed For A Demco Hijacker Autoslide 5th Wheel Hitch In A 2020 GMC Sierra 2500


Hi, I have a 2020 GMC Sierra Denali 2500. I just bought a 5th wheel and need a hitch. I was looking at the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider. My truck is 5th wheel prepped. Do I need anything to go along with the hitch to mount it? I think there is a Demco mount on your website website, do I need that too? I want to be certain I get everything Ill need.

If your 2020 GMC Sierra 2500 has the OEM puck system installed then you will need the Demco 5th Wheel Rail Adapter # DM6333 to mount into the pucks to mount the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550035 on.

If you do not have a puck system in the bed of your Sierra then you'll instead need the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit # DM39FR. This base rail kit has custom fit brackets to allow for an easy installation that requires no drilling into the frame.

The only other thing you might need is a 7-way connection like the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector # C56070 in the bed of your Sierra for easy hookup.
