How to Install the Demco 5th Wheel Rail Adapter on a 2018 Chevrolet Silverado 3500


Speaker 1: So today on our 2018 Chevrolet Silverado 3500 we're going to be taking a look at the Demco 5th wheel rail adapter for Chevy and GMC OEM 5th wheel towing prep package, part# DM6194. Here's what our Demco 5th wheel's going to look like once we have it installed. It's going to provide us with above-the-bed rails so we can use a standard 5th wheel. It's going to lock into our OEM prep package so we can use a standard 5th wheel instead of having to buy a separate one to work with the prep package. Now the really nice thing about this is it is going to be one solid piece. We're not going to have to assemble anything, and it's going to have really solid welds all the way around so it's going to be really strong.The only thing we're going to have to do is put in a single wing nut.

So installation's going to be really, really simple. We'll simply drop it into our factory puck system, rotate this silver lever so that it's back and forth, and then tighten down the wing nut and it'll be fully secure in our bed. Our adapter does have a rating of 21,000 pounds, but you always want to double check your hitch as well as your truck to make sure you don't exceed any of those numbers.Now our Demco adapter plate is a custom fit item. It's designed to work with the Chevy and GMC OEM prep packages. If you're looking for a way to adapt your OEM prep package to work with your old 5th wheel, or even just a standard 5th wheel, our Demco rail adapter's going to be a great solution for that.

It's a beginning installation. You're going to want to make sure you remove all the factory plugs for the pucks or the sockets that are in your bed. Now, it's a good idea to grab an extra set of hands. I want to bring your attention to this center area right here. This little silver bar, we want to make sure that it's going side to side before we put our plate in place.

WE're going to line up the pegs so that it drops in to the puck system, and then we'll rotate that silver bar so that it's going front to back.Now that the bar is facing front and forwards, you'll notice that it's going to line up two holes that are going to be threaded inside the base. So we're going to take our wing nut, and the star locking washing, we'll slide it over and then we're going to thread it in and make sure we tighten that all the way up. That's going to lock the ball bearings inside of here to make sure it doesn't come out. Now just to make sure it is locked in place, we'll go ahead and grab the base and lift up and make sure it doesn't come out. With the adapter securely in place we're ready to drop in our 5th wheel and lock it down with the pins.So, that'll finish up your look at the Demco 5th wheel rail adapter for Chevy and GMC OEM 5th wheel towing prep package, part#DM6194 on our 0218 Chevrolet Silverado 3500..
