Highlights

- Hands-Free Turning Clearance: Automatic slider gives 14" of travel for tight turns without leaving the cab.
- Strong, Secure Connection: Wraparound single jaw and 3/4" steel locking bar hold the king pin tight for stable towing.
- Smooth, Quiet Ride: Double-pivot head with polyurethane dampeners helps reduce noise and road shock.
- Built for Heavy Loads: Rated for 21,000 lbs GTW and 5,250 lbs vertical load to handle large fifth wheels.
- Level Your Setup: Adjustable hitch height from 15-1/4", 16-1/2", or 18" for proper trailer clearance.
Features to know about
Handles Tight Turns Automatically: 14" of Fore/Aft Travel with Built-In Rack-and-Pinion Gears
With the automatic slider, you don’t have to jump in and out of the truck every time you need extra clearance. The built-in rack-and-pinion gear system moves the hitch head up to 14" toward the tailgate during slow, sharp turns and then slides it back in line when you straighten out. That smooth, controlled motion helps avoid cab contact and binding—perfect for tight campground corners or crowded lots.
Locks In Solid for a Quiet, Secure Tow: Wraparound Single-Piece Jaw and 3/4" Steel Locking Bar
The wraparound single jaw completely surrounds the king pin for full 360-degree contact, giving you a firm, rattle-free connection. A solid 3/4" steel locking bar reinforces the latch so it stays locked once coupled. That combination cuts down on chucking and metal noise, making long hauls feel steadier and more secure.
Reduces Road Shock and Noise: Double Pivot Head with Polyurethane Dampeners
Built with a double-pivot head that moves front to back and side to side, the hitch stays flexible when you hit uneven roads or dips. Three polyurethane dampeners cushion those movements to absorb road shock and quiet the ride. It’s a small detail that makes a noticeable difference in comfort after hundreds of highway miles.
Adjusts to Match Your Setup: Three Height Settings from 15-1/4" to 18"
Whether your trailer rides high or low, the adjustable side plates let you fine-tune hitch height for a level setup. Choose from 15-1/4", 16-1/2", or 18" settings so your fifth wheel clears your bed rails and tracks straight down the road.
Simple Setup Right Out of the Box: Pre-Assembled Hitch with Included Base Rails
Installation is straightforward thanks to its pre-assembled design. Just bolt on the side plates, attach the head to the base, and pin it into the included above-bed rails. The sturdy steel construction with a rust-resistant black powder coat finish keeps it looking sharp and ready for many trips ahead.

Video Transcript for Comprehensive Review: Demco Recon 5th Wheel Trailer Hitch for Chevy/GMC and Dodge Ram
Hello, neighbors, I'm Steve here at etrailer.com. Today, we're looking together at the Demco Premier Series Universal Brackets for your 5th wheel trailer hitch base rails. Now, these installation brackets will mount beneath your truck bed, onto the truck frame, and then provide a nice attachment point for your 5th wheel rails. Now, those base rails are sold separately, and they would sit in the bed of your truck and then allow you to mount a 5th wheel trailer hitch onto those rails. Now, folks, this is all the brackets and all the hardware you're gonna get with you, you're gonna get the fish wire here. All the brackets here are made of a nice heavy duty black powder coated steel, it's gonna resist corrosion, rust, that kind of stuff.
Very, very nice finish on them, very heavy duty. And again, universal rail brackets, so you've got the slots in here, that way, you can slide them up or down, depending on the frame you're fitting it on. Now, the fish wire here is pretty nice. If you've never used one of these, it's got like a coiled up in here. What you would do is you would unwind this fish wire, you would pop it through where you need the bolt to come out through on the frame, you'd run it back through the frame, let's say down the frame, maybe a foot, foot and a half, I don't know, maybe less.
Then when it pops out, you simply screw your bolts into that fish wire coil. And then once it's on there, it's not going nowhere, that guy's in there tight. Then you could simply pull it through the frame, you can see I'm pulling pretty good on this, so it's not gonna come off. You pull it through the frame, you fish it down inside the frame tube, out the hole where you need it, then you simply undo the wire side, and that then would unthread, and then your bolt would be right inside the frame where you need it, so pretty nifty. Well, folks, again, all the hardware's included, it's made here in the USA, and again, a nice five-year limited warranty.
That's gonna do it for our look at the Demco Premier Series Universal Mounting Brackets. I'm Steve, thanks so much for watching.

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.

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.

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.

Best 5th wheel hitch ever for a RAM 3500 mega cab.
No issues with the RV coming close to the back of the cab or back glass.
I would recommend this hitch to anyone searching for a 5th wheel hitch for a Ram mega cab, I wish I knew about it when I first purchased my Ram mega cab, I learned the hard way, after busting out my back glass...and trying several hitches. This hitch is truly an autoslide. I have showed several short bed guys this hitch and told them the cost of the 5th wheel hitch is worth it.... It is top of the line. This will be the last 5th wheel hitch I will ever need to purchase.

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.

The product, bed rails and kit for 5th wheel hitch were good quality and installed easily enough, but the product was shipped in cardboard and it was heavy and broke through the box and some of the nuts and bolts were missing. Box arrived with big holes in each end. etrailer was good and shipped the missing parts but it cost me several days delay and unnecessary hassle. They just need to figure out how to ship without the box breaking up. Good product, good customer service, not so good shipping.

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.

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.

Made installing my Anderson Ultimate 5th wheel kit a snap! These rails are sturdy and well-made and will probably outlast the truck (which is still going strong at nearly 300,000 miles). I can tow my Bigfoot 5th wheel with ease and confidence.

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.

We received the hitch in great shape. The boxes were in very good shape. The only problem was a missing polyurethane dampener that was’t included. I called and received great service from etrailer. I have had a demco autoslide for several years but it was an 18000 pound hitch and went to a 21000 pound hitch. They are the best hitch for a shortened truck on the market

I think that etrailer requires their employees to lie so as not to have any confrontations with customers on the phone. I placed two orders on 8/23 and immediately received followup emails that order received, order processed by (employee name) and then is in stock with associated time each step completed.
Then I noticed that shipping date kept getting 1 day later each day I checked order status. So, I contacted etrailer on day 5, 8/27 and find out my item was not in stock at all and would not be until mid Oct. Well,I then had them order me the same part by a different manufacturer and was told that it was in stock and would still be still be shipped 8/28 and delivered on 8/30, the same day my fifth wheel hitch is being delivered, so everything seemed rectified until I checked order status online the evening of 8/28 and find that the ship date again had been pushed back another day 8/29 with a delivery date of 9/1, (which is a Sunday). Seems that at this rate I may have it sometime in September. Going by their assurance of delivery on 8/30, I arranged to pickup my new camper on 9/5, that seems to be an impossibility at this time because Order #121389499 the installation kit with base rails is a very necessary part of the assembly. So, in closing I can only say that if you do not have the parts to ship, be honest and state the truth. This has made me feel very negative now toward etrailor as I already had become with Camping World. Is there any honesty in the RV parts aftermarket?

Really like this hitch. Two things I don't like however, are 1) you need to backup almost perfectly the way you unhooked or it's a bear to hitch backup. 2) I don't like the bolts for the pinbox. Wish there was a quicker alternative. Hate getting a wrench out to tighten and losen.

The hitch and adaptor arrived in three days. Everything went together fairly easy considering I had just torn my rotator cuff a week earlier and my helper never showed up. Definitely would have been easier with two people. Had planned a trip next week to Yellowstone National Park but will have to wait until after surgery. Will do a follow up review after I am able to see how well auto slide works. Great customer service!

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

For example, The owner's manual for the Silverado 1500 Crew Cab, 4 wheel drive, 5800 V8, with an axle ratio of 4.10 lists a maximum towing capacity for the vehicle of 8,400 pounds. So as to not damage your truck, I recommend making sure the gross towing weight...

We have the Demco Hijacker Universal Base Rail Kit # DM8552009-71 as well as the Husky Universal Base Rail Kit # HT31563-686 which are confirmed to fir your 2002 Tundra short...
view full answer... - Recommended 5th Wheel Hitch for 2001 Dodge Ram 1500To determine the best 5th wheel hitch for your 2001 Dodge Ram 1500, you need the gross vehicle weight rating of your trailer.

For example, if your trailer comes in under 18,000 lbs, I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550034 and Installation Kit # DM8552009-71. This fifth wheel hitch features Demco's Autoslide, which makes turning corners easier by automatically sliding the head assembly...

The Hijacker FWH 24 PA identifies the 5th wheel hitch head but not the rails it is mounted to. It will require either the standard above bed ISR Rail Kit # DM8552009-71 or the SL Rails # DM6012 with Mounts # DM8553009 for your 1994 Chevrolet K3500.

This is a great 5th-wheel hitch that features a forged sing-piece jaw for a secure connection to the trailer and a towing capacity of 20,000 pounds.

- 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.

- 2500 or 3500 Series Truck Recommendation for Towing Trailer 14,500 lbFor a trailer that weighs, 14,500 lbs I would strongly recommend a 3500 series truck. Even if the 2500 could technically tow it the 3500's higher rated suspension will make for a much better towing experience. Less sag and a smoother ride when towing. The ride quality will be a bit stiffer unloaded but that's not why you need the truck. I'd also recommend a long bed truck so that you have turning clearance without needing a slider hitch. I'd also recommend a dually rear axle as that adds...

They MUST be evenly on both sides to 1/8" more than the width of the pin box.

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.
