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.


Automatic Slider Makes Cornering Easy

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.


Demco Hijacker Autoslide

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.


Demco Hijacker Autoslide capture bracket

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.


Secure Wraparound Jaw with Locking Bar

Demco Hijacker Autoslide wraparound jaw and locking bar

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.


Double-Pivot, Cushioned Hitch Head

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

The Autoslide hitch is designed to attach to universal above-bed base rails . The hitch will fit most industry-standard rails, including those from B&W, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley. The hitch comes pre-assembled for an easy installation. All you have to do is bolt on the side plates and attach the head to the hitch base.


The side plates have 2 functions. They contain the feet that fit into your above-bed 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.

  • 5th Wheel Hitch Options For A 2017 Ram 3500 With A Bradford Flatbed
  • Hey Joe, Does your Bradford flatbed have a recessed gooseneck hitch already installed or is it just the flat bed right now? If not, you're going to need to cut out space for a gooseneck hitch like the B&W # BWGNRK1500 to be installed. From there you would need a 5th wheel hitch that mounts to a gooseneck ball like B&W's flat bed hitch # BWRVK3050. The bed height for a flatbed is typically a lot higher than a standard bed so a shorter hitch is typically going to be required so that the

  • Could Above Bed Demco Hijacker Hitch Fit Same Rails and B and W Companion Hitch
  • The B and W Companion hitch was designed to fit the underbed B and W gooseneck hitches and no a standard set of fifth wheel rails like it sounds like you have/were describing. The Patriot hitch from B and W is the hitch that normally fits that style of rails. If the rails you have are 22 inches apart that would indicate you have standard rail kit. The Demco Hijacker for above bed rails part # DM8550035 was designed to fit this type of rail and would work great. If you have something

  • Best Sliding Fifth Wheel Hitch Recommendation for 2017 Ram 3500 Short Bed with Factory Rail Kit
  • For a slider hitch for your 2017 Ram 3500 with the factory fifth wheel rail kit the best option I can recommend is a Demco Hijacker Autoslide hitch like the part # DM8550035 which has a 21k capacity. I really like this hitch as it automatically slides back as you make tight turns so you never have to get out and mess with the slider mechanism. Then to fit this hitch to the factory rail kit of your truck you'll need the rail kit adapter part # DM6099 and you'll be set. I attached a

  • Adapting Demco Autoslide 5TH Wheel Hitch To Fit Factory Prep/Puck Bed On a 2023 GMC Sierra 2500

  • Adjusting The Height Of A Demco Hijacker Autoslide 5th Wheel Hitch In A 2021 Chevy Silverado 2500

The difference between these two numbers is what you want your hitch's height to be.
