Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


I have to say I was very pleased with my unit it only cost $xxx to have installed and it fit perfectly for my truck a eight 2004 F2 50 super duty short bed I pull a 30 foot Alejo fifth wheel and my driveway is only 60 foot wide with my truck it’s 17 feet high turn that truck on a dime I would never have been able to get that RV out of that driveway if I did not have my sliding hitch which allowed me to turn my truck at a 90° angle from the trailer and pivot like a compass. I love this hitch and I will never own another

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


So easy to install! I’m not overly handy and was able to complete in about an hour. Slid right into the puck system and bolted on from there. Was able to keep my bed liner in, just removed the bumpers from the bottom of the plate. Haven’t had any issues with the hitch after 5k miles of towing over the summer. GREAT PRODUCT!!

I have never assembled a 5th wheel receiver before.
This is an excellent product that could have had better instructions.
It pulls a 2022 Attitude 3220SAG.


Comments
Can I switch heads from a 16k to 21k or do I need to buy all new setup

After one year this product is still excellent.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


Ordered this hitch 3 day shipping on Monday around noon and received Wednesday afternoon. Packaging had taken a beating, but no damage to hitch, and all parts where there. Assembled hitch piece by piece in the bed of my Ram 2500 short bed. Went together like clockwork. Took be about 2 hours, taking my time because it was 93 degrees in my garage. Picked up new 34 foot fifth wheel RV that Saturday. Hitch locked on to pin with a reassuring solid lock sound and towed well. Very happy with eTrailer and Demco.


Comments
Overall happy with the hitch. My one complaint would be that if the king pin does not go into the latch just right, it will not latch. It sometimes takes 3 or four attempts to hit at the Just the right angle, not large movements, Usually just have to pull forward, turn the wheels a bit and back into it again. This doesnt occur on every hitch up, but happens more than I care for.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


Just back from a 500 mile first use on some of Wisconsin's wonderful roads. New hitch is definitely a step or or two above my old hitch. Package arrived slightly damaged, but contents were well protected inside. Installation was very easy.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


After having this hitch for one year, I’m pretty disappointed. This hitch has the most play of any hitch I’ve ever had. The curt hitch I have has no play. Also the the handle for the slide is not very user friendly. If you pull it too hard it will simply pull out of one side. It will get the job done if you don’t have any other choice. The only reason I purchased this brand was because it was the only brand I could get during Covid.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


I ordered this hitch for my 2018 Titan XD. Very well made hitch. This install does take about 2 hours if you are assembling it by yourself. The parts are heavy as due expected for such a solid hitch. I did find that installing the base plate to the factory gooseneck hitch with a drop in bed liner does require removing all the shims from underneath the plate. If possible, assemble this hitch in the bed of the truck. The parts assembled complete makes for a very heavy hitch to put in the bed by yourself. I had to due to storms the night I assembled it. Due to shipping damage, I had to get replacement parts sent to me but Lori was very fast to get them to me. I pull a 13.5K trailer and it worked flawlessly. I am very, very pleased with the finished product as well as the excellent customer service from etrailer. You will NOT be disappointed.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


This Slider hitch was a perfect fit for my Silverado 2500 standard bed. The several height adjustments gave me the height I needed and the shorter slide gave me the distance I needed to clear my cab window and still clear the truck bed without any worries. I highly recommend it

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


Really heavy duty. Easy to install in my 2019 Ram 2500 on my existing rails. Slides nicely when backing my 32' camper. After recently knocking out my back window with my stationary 5th wheel hitch.

The installation of the hitch was quite simple once the base rails were properly installed.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


The hitch is great and the extra locking bar does ensure a safe hookup. The ability to pull the hitch and leave the base plate in so i can still use the bed is awesome.The only two downsides i would say are that the paint chips rather bad even in areas that have had no contact with anything which allows the hitch to rust. The only other piece is that even though this model is made for my truck it still rocks back amd forth a bit and the cotter pins fall out which allows the retaining pins to slide out as well. This can be fixed with some simple retaining wire.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


I purchased a 2019 Titan Diesel. The Demco Hijacker system was one of the few hitches to work on the Puck system. I had to get rid of my Ford F250 after so many mechanical problems and that hitch did not work on the Titan. Pulled my 5th wheel to go hunting last year with no problems. Have taken the hitch off and on with no problems. System works very well. Pleased with purchase. The slide works a lot better than the other hitch I had.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


As always, great service from etrailer. Great prices, fast shipping.

As far as the product...Let me start by saying that Demco make absolutely first rate hitches. My only (constructive) criticism might be that their quality control might not be quite up to snuff. This is the second Demco hitch I've purchased, the first being a 21K Autoslide hitch. Again...fantastic product but upon arrival one of the four tabs that drop into the bed rails was welded on upside down. Demco replaced the part, no questions asked, terrific customer service. This 21K double pivot hitch arrived yesterday and went together well except one of the tabs wasn't welded perfectly squarely which made it extremely difficult to get it to drop into the existing bedrails (which worked perfectly for the prior Demco hitch). Managed to get it in...getting it out...well, that may be a bit of a challenge. Wouldn't stop me from purchasing another Demco product though.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


Overall a very good product. Everything I expected, works as described, easy installation, easy to remove if need be . I wanted the slide hitch for cab clearance and this model is the right choice and works perfectly for my application.
Will buy again.

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


Wow, new 2019.5 Ram 1500 works perfect..connected to Artic Wolf 285RL 3 slides 8,500 loaded.. turns up to 70degrees don,t need slide w the artic wolf. The installation was long..did it myself. Bracket bolts directly above frame was testy.. Had to grind a little off drivers rear bracket to fit. It was overall a tight fit but from an engineers point of view...small 5.7 bed there wasn't much room or choice. Tammy it was a pleasure working with you. Great Price, Great service, Thanks again...

Review from a similar Hijacker Premier Series in Fifth Wheel Installation Kit


We bought a new style 2019 Dodge Ram 1500 and where told there was no 5th. wheel system built yet to fit it...all on back order. Found this on etrailer website easily, and the order was seamless, had it within 3 days!
This unit does fit the new style 2019 Dodge's. Had it professionally installed and very happy with it.
Thanks!

  • Above Bed Demco Fifth Wheel Rail Kit Recommendation for 2020 Chevy Silverado 2500 Short Bed
    If neither truck has the puck system that would mean the Demco Hijacker is one designed for above bed rails which means you'd only need a set of above bed rails installed in your 2020 Chevy Silverado 2500 like the # DM39FR and you'd be set.

  • Can the Demco Hijacker DM8550034 Fit a Silverado 5.8’ Bed?
    The Demco Hijacker # DM8550034 should not be used on beds shorter than 6 feet long. This is due to the the bed not being long enough for this slider to slide back without the trailer pin box hitting the tailgate. However, we do still have a sliding option available for the 5.8 foot bed on your Silverado. You will want to look at the Demco Hijacker Autoslide # DM8550040. This 13,000 pound capacity hitch is specifically designed for use with the the beds that are under 6 feet and will still...

  • Can You Install a 5th Wheel Hitch On a 2021 GMC Sierra 2500
    Yes, you can install a fifth wheel hitch on a 2021 GMC Sierra 2500 with Carbon Pro Bed. For this, I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550034 with Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit part # DM39FR as the auto-slide mechanism will eliminate having to get in and out of the truck each time to make a sharp turn.

  • Best 5th Wheel Hitch For 2020 Chevy Silverado 2500 Short Bed Without OEM Prep Package

You need a slider for cab clearance when towing with the short bed truck. The Demco HiJacker is an auto slider which creates a much more convenient and enjoyable towing experience.

    Yes, I do have an auto-slide fifth wheel hitch option for a 2020+ Chevrolet Silverado 3500, the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550035. In order to use this hitch you will need the Demco 5th Wheel Rail Adapter part # DM6333 if you have the factory prep package or the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit part # DM39FR if you don't.

  • Parts Needed to Install Demco Hijacker in 2021 Chevy Silverado 3500 Short Bed
    If your 2021 Chevy Silverado 3500 short bed has the OEM rail kit you'd need the rail kit adapter part # DM6333 to install and use the Demco Hijacker part # DM8550035. If instead you didn't have the OEM rail kit you'd need the rail kit # DM39FR with the same hitch # DM8550035 and you'd be set. The Hijacker will work great with the Lippert 1621 you have now. Another great option is a fixed hitch with a Sidewinder that can fit your trailer in place of the 1621 with part # RP34FR.

  • Recommended Sliding 5th Wheel Hitch for 2021 Chevy Silverado 3500 Short Bed
    The puck system is not something that is there unless you have the 5th wheel prep package on your 2021 Chevy Silverado 3500, so you will need to get a rail system as well as a 5th wheel wiring harness in order to use a 5th wheel hitch. Since your Chevy 3500 is a short bed, you will need a sliding hitch, and while you mentioned you were looking at 25k hitches, there aren't any with that capacity for your short bed, but there is a 21,000 lb option that is one of the best hitches available,...

These options are if you want to use above-bed adapters. If you wish to install below-bed adapters, you will need the # DM8550037 (21K) or the # DM8550022 (18K).
