Note: This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.
Most often used on trucks with 6-1/2' beds, a slider helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a slider to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.
Normally, you'd have to get out of your truck and pull a lever to release the slider before every turn, but what if there was an automatic system? Imagine having 14" of extra clearance while towing your fifth-wheel trailer. Now imagine having this without needing get out of the truck to move your slider. The Demco Autoslide makes this fantasy a reality. The Autoslide automatically glides back smoothly when you make a sharp turn so you can maneuver effortlessly around tight corners within campsites and parking lots.
The base of the Autoslide has a built-in rack-and-pinion gear system that operates automatically. As your truck turns, the pinion in the base also turns. This activates the rack gear, which causes the rotational force of the truck to be converted into the linear sliding action of the hitch. So, when your truck makes a sharp, slow-speed turn, the gears inside the Autoslide force the hitch head to slide down toward your truck's tailgate in a smooth, controlled motion. This way, any time that your truck turns more than 10 to 15 degrees, the Autoslide will ensure that there is enough clearance for your trailer to complete the turn as well, and it will do so without any jerking or binding.
In order for the rack-and-pinion assembly to function as designed, the pin box must be stabilized on the hitch head. Normally in a fifth-wheel hitch, the king pin moves inside of the hitch head so that the trailer can turn. With the Autoslide, the king pin remains fixed inside of the jaws of the hitch and it is the hitch head itself that turns. This is thanks to the capture brackets on the sides of the head that brace the pin box from both sides to hold it in place on top of the hitch head. This is done to ensure that there is enough resistance within the hitch when your truck turns to properly activate the rack-and-pinion gear mechanism.
To stabilize your pin box on the hitch head, simply push the capture brackets up against your pin box once the trailer is coupled and tighten the outer bolts and the inner jam nuts. The Autoslide head and brackets will fit standard pin boxes that are between 12" and 14" wide. If you have a Glide Ride, Mor Ryde, Trailair Tri Glide, Rota Flex, Lippert Road Armor, or 5th Airborne pin box, you must install a special locking plate (sold separately) as well.
When you straighten your rig out again and your trailer moves back in line, the hitch head will rotate back to center and slide back toward the cab into the straight towing position.
The single-piece, strong wraparound jaw completely surrounds your trailer's king pin for 360 degrees of contact. This wraparound jaw provides a more secure connection than standard 2-piece jaws that close in on the king pin from the sides. The increased jaw-to-king-pin contact on the Autoslide offers tighter tolerances around the king pin, which minimizes both rattle and chucking, for a smooth, quiet ride.
A 3/4" solid steel locking bar spans the area in front of the jaw. This bar provides an added barrier of protection against accidental disconnection so you can have peace of mind that your trailer is secure. The locking bar is attached to the jaw and to the spring-loaded handle. The bar automatically locks when the jaw closes around your king pin.
The double pivoting, cushioned head improves your towing experience dramatically by helping to reduce jarring and unwanted noise. Built-in pins allow the hitch head to pivot back and forth and side to side. And hooking up is easy because the hitch head will automatically pivot to the proper angle when it comes into contact with your pin box.
Three polyurethane dampeners help to cushion the movement from the pivoting head and to reduce towing noise. Two of these dampeners are built into the head assembly to cushion the head's side-to-side pivoting. The third dampener cushions the back-and-forth motion and must be installed in the hitch prior to use. Installation of this third dampener is easy - simply press the dampener up into the pre-drilled hole underneath the hitch head.
Easy Installation
Included with the Autoslide hitch is a rail adapter that's specific to the Chevy/GMC factory prep package. Just drop the adapter into the puck receivers built into your truck bed and lock them in place. Then you can position the pre-assembled hitch base in your bed and easily pin it to the rails. Just bolt on the side plates and attach the head to the hitch base, and you'll be ready to tow.
The side plates have 2 functions. They contain the feet that fit into the rails, and they allow you to raise or lower the hitch head to better match your pin box height. After you choose your desired height setting, simply bolt the side plates to the hitch base with the included hardware. Then attach the base to the rails with the included safety pins.
Clearance Formula for Short Bed Trucks
Use the formula below to ensure there will be enough space between your truck cab and trailer when executing a 90-degree turn.
(A+B) - C = Clearance
A = Distance from the center of fifth-wheel hitch jaw to truck cab
B = Length of Travel (14")
C = Width of trailer divided by 2 (to get half)
For example: If the distance from the center of the hitch to the cab is 36", 36" + 14" = 50". If your fifth-wheel trailer is 84" wide, take half (42"), then plug in: 50" - 42" = 8" of clearance.
Note: At least 4 inches of clearance is recommended to safely execute a 90-degree turn.

Hey, guys. This is Jake here with etrailer. Today we're gonna be taking a look at the Demco OEM GM Puck System Rails. These are gonna drop directly into the factory puck system on your GM truck. So, that's Chevy or GMC. And it's going to have two different rail options.
The only one that you're missing is the widest rail option. So, most of them are going to fit in the two center ones. There are some wider kits that have higher capacities that'll fit in these outer ones. This rail kit is gonna have a capacity of 25,000 pounds. Has a nice, thick black powder coat finish, that's gonna help resist rust and corrosion.
Demco does a really good job with their paint jobs. It's textured, so things are gonna be more likely to slide off of it, than to grab onto that paint and cause any scratches or chipping. One of the nicest thing about this kit is that it's gonna drop directly into your puck system. You can lock it in by pulling these levers. Something I like about these is that the levers actually have a direction that they're supposed to go in, and then you can put the pin in to lock them in place.
I will say, if you have trouble getting these latches to match up to the pucks in the floor of your the bed of your truck, what we did was we just loosened these four bolts on each of these brackets, and then it was able to move just the slightest bit to get them dropped down in place, and then we torque them down again. So, once you get it set, it's great. I like it because you don't have to make the initial investment of getting a new fifth wheel hitch just to match it to your truck bed. If you like to get trucks every couple of years, a lot of people don't like to put a lot of miles on their truck. They'll get a new one.
If you get the same truck, you can take this set of rails, put it in the new truck bed, and it match up great. If you decide to go with a different brand, you just have to get a new rail kit. You don't have to get a whole new fifth wheel hitch. Well, guys, hopefully this video helped you decide whether or not the Demco OEM Puck System Rails is gonna be right for you and your vehicle.
