  • Stick to towing your fifth wheel and don't use your truck bed for much else

  • Plan on traveling on rough, uneven roads - the autoslide's been known to bind
  • Tow a very wide trailer and don't have an extended pin box
This hitch slides automatically as you drive to give you 14" of additional clearance for tight turns. A wraparound jaw provides a smooth ride and a locking bar offers added security.

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 Hijacker 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, 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 Hijacker Autoslide hitch is designed to attach to universal above-bed base rails (sold separately) . 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.

This review is for the Demco Autoslide 21k and accompanying OEM rail adaptor I purchased for a 2020 Ram 3500 Megacab DRW. I've owned it one year. Overall, the hitch performs as I expected. It is high quality, very sturdy and seems like it will last for a long time. I had it installed at the dealer when I purchased the truck. It automatically slides to protect the cab in my 6'4" bed without any incidents. I tow a standard fifth wheel RV. There are a few negatives, which are not necessarily shortcoming of the product but, instead, necessary evils to allow me to have a short bed. First, it is BIG and BULKY. I believe this is just a function of the mechanism required to allow the autosliding feature and I am not really sure there are any other lighter alternatives with this feature. The fact it requires two parts (OEM Puck Rail and hitch), make it even more bulky. It takes up almost the entire bed and prevents most auxillary tank / tool box combos from fitting. Even standard size storage bins will not fit in my bed. I would prefer if they had a custom OEM all-in-one hitch for my truck like they do for the Ford. It adds significant weight, which decreases carrying capacity, which can be at a premium in hauling a heavy fifth wheel. I've never even tried to take it out of the bed due to the weight and difficulty. I also am not very happy with the adjustable catch plate design. It requires significant manipulation loosening and tightening 8 nuts when hitching and unhitching. This requires a step ladder to reach the nuts. I also found out after the fact that it does not come with the right size catch plate attachments for my hitch and I had to purchase a separate part, which added unexpected expense and delayed my taking the RV on its first trip. Overall, I am satisfied with the hitch.

- DM8550035

Works great except life would be so much simpler if they had a hole drilled on each side to remove the lock pins that are below it in the mounting plate to be able to remove the unit from the truck.

Thank you for the review! While I do see where a hole in the mounting bracket would make this easier to remove with your Adapter Plate # DM6333

, a solid bracket in this instance is much better for strength, especially considering this hitch is designed around the universal rails for trucks.

Pretty pathetic service from etrailer. Order place on Aug 25th with ETA of the following Friday (1o days). But nope, I wait. It finally (and supposedly ships) on Sept 7th (13 days later). On Sept 14th I received a confirmation that my items were delivered, but nope. Not to my house anyway. Avoid these folks if you want something to arrive when they say it will arrive.

Thank you for bringing this to our attention. Our customer service team should be reaching out to you in the near future.

This is an initial impression review. The hitch was delivered on a pallet and arrived earlier than expected. Everything was well packaged with all associated hardware. This hitch was mounted on Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches ( in the bed of a 2007 Dodge Mega Cab 3500. Overall it appears to be well constructed, unfortunately, I did have issues with bolting the hitch adapters to the hitch. The hardware is either grade 3 or 5 (looks like 5) and did not torque well. I had one bolt that stretched and sheared before I reached the torque spec (photo attached). I'm not sure if this was designed to use the weaker hardware or a business decision, however, all eight bolts were replaced with grade 8. I do look forward to utilizing this hitch in a few months. I would at photos, however it appears that I can't.

- DM8550035

It works really well. It is really nice not to worry about the 5th wheel trailer clearance when making tight turns. We pulled the rig several hundred miles last summer and at least 3000 more since January with no issues. Also I used the height adjustment feature when setting up my trailer. When I received the shipment I was impressed by how well it was packed. It would have been nice to had had help, but I was able to assemble and mount it myself. The instructions were good, and as I said, we have had no issues during our first snowbird season.

- DM8550035

Purchased a heavier 5th wheel so this one replaced my pull rite. No more capture plate to deal with. Very happy with this hitch.

- DM8550035

Worked good but a lot of adjustments. They sent the wrong capture plates. Demco customer support was great.

In the description it says locking plates, sold separately, are required for the Rota-Flex Pin box that you have. Item # DM6171

- DM8550035

Great hitch. No capture plate to deal with, you can hook up to any 5th wheel. No more greasy pin box. No more watching the mirror wondering if your going to hit and damage the cab of your truck. Works perfectly. Built solid, though I did purchase the 21K for a 15K 5th wheel. Easy to lube. The only drawback I had was that it sat just a little bit high in the truck even on the lowest mounting holes. If you are thinking of purchasing this you may want to take some measurements first. I have an 08' F350 SD with air springs so it does set high. Before I bought it I called the factory (easy to reach and eager to help) and asked them, among other things," if the hitch broke, could I easily get parts for it?" They replied that if you need parts we will get them to you wherever you are. Overall I think this is the best hitch on the market.

After about 6000 miles the hitch developed some fore and aft movement. After another 2000 miles it seemed to be excessive with a loud clunk when stopping and starting. Yes, I do grease it as per instructions before each trip. I called Demco and told them the problem and they sent me the parts I needed at no charge since it was under warranty. Since I had the mechanical ability I disassembled, diagnosed and repaired it myself. I thought later on that I should have been compensated something for my time only because if I took it to a dealer they would have charged for labor. Just a suggestion, there needs to be an easier way to lubricate this hitch rather than removing the large pivot pin and also the large pivot bolt and greasing them by hand. Some well placed grease fittings would make this job a lot easier and cleaner, especially when on the road. Also, the hitch owner would be far more inclined to do it. Other than that the hitch has performed great and I am very happy with it. Thanks.

This is a quality piece of equipment. I can't wait to use it. The installation directions were complete and easy to follow. Looks fantastic.

Had a set back on the shipment, but the service and responded was some of the best I've ran across. The equipment came before the give delivery date. Everything was in great condition, good communication.

- DM8550035

Bought for use on my 2019 Ram 2500 shortbox because I was having clearance issues while turning. I could barely make a 45 degree turn. Installed the unit in about an hour from delivery to finish. Have an extra guy or two to help cause its heavy. I can know back 90 degrees if I had to with about 4-6 inches of cab clearance

- DM8550035

Extremely well made product and as always arrived in perfect condition. Etrailer is my go to for all things trailer related and is the first place I look!! They have the best prices around and stand behind every sale which gives me confidence in every purchase. I love this hitch and look forward to many years of towing with it! Thank you again etrailer!!

- DM8550035

It works very well. I'm very happy with it. Thanks

- DM8550035

I had trouble with this hitch at first. I could not get it to close and latch properly when I backed into the king pin. I worked with tech services and ended up replacing the inner pivot parts and I have really not had any issues since. Because I have to have the locking plate for my pin box, you do have to line up the truck just right for it to latch properly, but once you figure that out, it is easy. The auto slide feature works really good. I have a short bed RAM truck and I have completely turned 90 degrees with my trailer attached and it slides back with no issues to miss my cab. I highly recommend this hitch. Also the Demco Tech Services guys are great to work with.

- DM8550035

Good hitch but very heavy and hard to maneuver If that's not an issue it works perfect Don't have to worry about turning with 6,4 bed Etrailer great job shipping , etc

- DM8550035

If you have to have a slider this is the one to buy. I’ve now driven with it about 5000 miles..the only down side is that you have to hook and unhook with the truck perfectly straight in line with the trailer. But it does work perfectly as advertised.

Great, customer service with [Demco Representative] could not be any better..he knows this hitch like the back of his hand . I would buy another just because of him.

Nice unit. But snapped bolts on side plate may want to up grade to a grade 8 bolt. Will see next yr how well it works!

- DM8550035

Very happy with the product. The only draw back is the weight. Can't be loaded/unloaded by one person. A good cross-sell opportunity is to offer a tool for removal. When I first got it, it didn't fit the truck. Support team was helpful and responsive. It seemed to be due to the bed spray. I was able to get it to mount perfectly by loosening a bolt under the truck, and then smoothing the edges of the locks in the rails.

- DM8550035

Have yet to use it so but like what I see so far.

    The only sliding 5th wheel hitch we offer which does not require getting in and out of the truck bed for tight turns is the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550035 which has a 21,000 lb rating and can be used on a 2019 Ram 2500 with Demco Hijacker Premier Series Above-Bed Base Rails part # DM8552025-71. In regards to hitch height settings, you can use the lowest option if needed but keep in mind this is not really a preference sort of thing so much so that it is...

  • 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...

  • Demco Hijacker or PullRite SuperGlide for Short Bed on a 2016 Ram 2500
    The Demco Hijacker Autoslide # DM8550034 is definitely the better option over the PullRite SuperGlide 4400. Although they do share some similarities (like the autosliding function, single-jaw to secure the king pin, and cushioned heads) the Demco stands out because it has 3 different height settings, 15-1/4", 16-1/2", and 18", features a 3/4" steel locking bar to reinforce the king pin connection, and doesn't require a locking plate unless you are using a special pin box. The PullRite...

  • Recommended 5th Wheel Hitch to Reduce Chucking with 2016 Ram 3500 and Trailer
    A cushioned pin box replacement on the trailer will help somewhat with the chucking you are experiencing, but the hitch itself will make the biggest difference, specifically the jaw design that it comes equipped with. For your 2016 Ram 3500 with the 6-1/2 foot bed (if it does not have the factory rail kit), I recommend going with the Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550035 with the Base Rails and Custom Installation Kit # DM8552026-71. This is an excellent, heavy-duty...

  • Recommended Demco Hijacker Autoslide Compatible with 2012 GMC Sierra and 2021 GMC Sierra
    I have a solution for you, but Demco does not make a hitch that will drop directly into the pucks on a GMC truck, so you would have to use an adapter on the new truck. For the hitch, you can use the Demco Hijacker Autoslide # DM8550035; this hitch has a 21k capacity and will fit into industry standard base rails or the adapter mentioned below. I think it's always a good bet to go up to a higher capacity if there's a chance that you might end up with a trailer that's higher weight; so if...

  • Recommended Fifth Wheel Hitch for 2017 GMC 2500
    With a short bed truck like your 2017 GMC 2500, you will need to use a sliding fifth-wheel hitch to avoid contact between your Sundance and new truck when making sharp turns. I recommend taking a look at the Demco Hijacker # DM8550035, which has an automatic sliding system so you do not have to get out of your 2500 to engage the slider when turning. This hitch will install with the Demco 5th Wheel Rail Adapter # DM6194, which simply locks into place via the puck system in the bed of your...

  • Adjusting The Height Of A Demco Hijacker Autoslide 5th Wheel Hitch In A 2021 Chevy Silverado 2500
    When determining the height of your 5th wheel hitch you'll need to measure the height from the ground to the floor of the bed (where the base of the hitch will be sitting) and the height of the ground to your king pin when the camper is level. The difference between these two numbers is what you want your hitch's height to be. For example: if your truck bed height is 42" tall and your king pin height is 58" then you would have a difference of 16". The Demco Hijacker Autoslide 5th Wheel...

  • 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...

  • Comparing the Pullrite SuperGlide and Demco Hijacker for a Ram 3500
    The Pullrite SuperGlide 2315 is a great 5th wheel hitch in general however, it won't be best for your 2018 Ram 3500. The reason for this is because the height of it cannot be adjusted and the new Ram has pretty tall besides so you are going to need a 5th wheel hitch that can be adjusted vertically to account for this. For that, the best option we have for you that will allow you to retain the auto-slide function is the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550035 with...

  • Can Demco Hijacker Auto Slide Hitches be Used with Rota Flex Pin Boxes

  • Auto Slide Fifth Wheel Hitch Recommendation for 2018 Ram 3500 with Air Suspension
    I have a great solution for you. The Demco Hijacker AutoSlide Hitch part # DM8550035 is designed to fit industry standard style fifth wheel rails. So while the Demco brand rails for your truck don't fit with the air suspension vehicles, the Curt rail kit part # C16430-204 does fit the air suspension versions of your 2018 Ram 3500 so it would work well. The hitch I mentioned has a 21k capacity and will automatically slide as you make tight turns.

    The Demco Hijacker Hitch part # DM8550035 that you referenced has been confirmed as a fit for your 2017 Ram 2500 with hitch package and short bed as long as you use the adapter part # DM6099 and would be what I would recommend for you. It would not require any rail kit adapters either. It is very similar to the Pullrite Superglide in operation. I have read many online reviews on other sites and forums where people compare the two saying that the Demco costs less and tends to be more...

  • Can Demco Hijacker 5th Wheel Hitch Hook Up to a Trailer at a 45 Degree Angle
    The issue with the angle restrictions on Demco 5th wheel hitch # DM8550035 is the auto-sliding feature. In order for it to engage/disengage properly when hooking up/unhooking it can only be at the 0 to 15 degree angle. A manual slider such as the Curt A20 # C16541 would be a better option.
