Under Bed Rail Kit for Demco DM8550022 Auto Slide 5th Wheel Hitch on 2020 Chevy Silverado 2500
Question:
I have just purchased a 2021 Chevy Silverado 2500HD Z71 LTZ. I really like the Demco DM8550022 Auto Slider function of this 5th wheel.. My question is since my truck DID NOT come with the pucks already installed do you have a kit for this truck that will allow me to put the rails below the bed. I see that you have a kit, but when I put in my new model, I did not get any hits.

Helpful Expert Reply:
We'd be glad to help you with that. Demco does make an under-bed rail kit that's compatible with their
# DM8550022 Hijacker Autoslide hitch that will work with your 2021 Chevy Silverado 2500. You'll want to use the # DR37FR under bed rail kit. I've linked to the installation instructions for you.
The Hijacker Autoslide is a great choice, and will be very convenient as you won't need to get out of the truck to manually actuate the slider.
If you'd like an in-bed 7-way trailer connector you to don't need to run the trailer connector up over the tailgate, you can install one using part # HM54FR. You an see a video of this being installed by using the provided link.
