How to Use Underbed Demco Hijacker Autoslide 21K in Bed of 2019 GMC 3500 Sierra with OEM Rail Kit
Question:
We bought this hitch system for our 2012 GMC 2500 Denali and just upgraded to a 2019 GMC 3500 Denali with the factory undermount puck system. The side plates are too short for the 2019 - what side plate replacement will fit?

Helpful Expert Reply:
You'll need to install the above-bed style side plates on your Demco Hijacker 21k with part # DM6003 so that you can use the GM rail kit adapter for short bed trucks part # DM6194. This adapter fits the rail kit in your 2019 GMC 3500 Sierra short bed and will fit your Demco hitch once you install the side plates # DM6003 on them.
