Video Transcript for Review of Demco Fifth Wheel Installation Kit - Universal 5th Wheel Install Kit - DM8552009-71

Hello neighbors. Welcome back. I'm Steven here at etrailer.com. Today we're taking a look together at our Demco Premier Series Above-Bed Base Rails and the Universal Mounting Kit for your Fifth Wheel Hitches. Now folks, this installation kit will let you mount your Demco Premier Series Fifth Wheel Trailer hitch in the bed of your truck, but it also works with B&W, Curt, Draw-Tite, Hidden Hitch, Husky and Reese Fifth Wheels as well, and the valley above-bed fifth wheel trailer hitches. Now folks, the mounting brackets, these L-shaped brackets here, they are gonna install beneath the bed of your truck.

They're gonna provide a nice attachment point for the above-bed base rail themselves. Now you will get all the included hardware that you see before you. There's lots of spacer blocks here, some other spacer blocks, the nuts, bolt, lock washers, and you even get this fish wire guy. And if you've never seen one of these, they're pretty nifty. Basically, you will route this through the frame and you would simply thread on a bolt to it just like so.

So that guy's hanging on there, he is not going nowhere. You would unwind this. I'm gonna leave it coiled up now just 'cause they're kind of hard to get back together. But you would fish it through, I don't know, let's say there's a hole in the frame. You'd fish that wire through and then you'd be able to pull that bolt through the hole up and through from even, I wanna say, at least two feet away sometimes.

So pretty impressive the way this fish wire works and you just simply unscrew the bolt to get the fish wire back off. So again, pretty simple operation. Everything here is a nice sturdy, sturdy black powder coated steel finish. It's gonna reduce rust, corrosion, that kind of stuff. And again, you're gonna get two base rails, all the bracketry and hardware included, along with that fish wire as well.

Everything's made here in the USA and it has an amazing five year limited warranty. Well, folks, there's not much more to say about this other than to kind of show you these base rails. If you've ever installed these, you kind of know already what they are. If you haven't, pretty simple. All these rectangular slots in here, those are where the legs of your fifth wheel will put in. And then these side holes here, you would put through like a pin to hold that fifth wheel leg into place on the rails. So keep in mind with base rails, these rails are flat in the bed of your truck, but they are raised a little bit. So it kind of has that same hat channel shape that you see in a lot of beds on trucks. You will have that same rail in the bed of your truck. So just keep that in mind as far as space, height, that kind of stuff. If this kind of kit's not what you're looking for, maybe you want a more sleek, hidden, we do also make those kits and sell them as well. So those are available at etrailer.com as well. Those would be what's called an underbed or a hidden fifth wheel install kit. Well, folks, that's gonna do it for our look today at this Demco Premier Series Above-Bed Base Rail Kit. I'm Steven with etrailer.com. Thank you so much for your time today. Use our fit guide etrailer.com. Enter the year, make, and model. Make sure you're getting the right parts for your vehicle. Have a nice one.

Install your fifth-wheel trailer hitch in your truck bed with this kit. Universal brackets, base rails, and hardware included.

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.



by:

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.

There was an issue with the address on our debit card so payment in our order didn’t complete, we received a personal email (not just one of those automated ones) regarding the matter, when i called to correct the staff were super friendly and helpful. Our package came right on time for instal!

  • Availability of Underbed System or Replacement Legs for a Valley 5th Wheel Hitch on a 2001 Dodge Ram
    Since Valley went out of business there are no underbed systems of replacement legs available for you to convert it to fit in-bed base rails. For your 2001 Dodge Ram with a 6 foot bed it is recommended to use a sliding 5th wheel hitch as that will give you the clearance that you need to avoid hitting the cab on your truck when making tight turns. If you are wanting to go with a hitch that is under the bed of your truck then I recommend the B&W Underbed Installation Kit # BWGNRK1394-5W....

  • Fifth Wheel Hitch Recommendation for 2005 Chevrolet Silverado 1500 LD 6.5 Foot Bed
    First, I recommend checking your owner's manual for your Silverado's maximum towing capacity. From what I found, Chevy has determined that fifth wheel and gooseneck trailers should not be towed with the 2005 Silverado 1500 Crew Cab. 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...

  • Will Chevy Silverado Demco 5th Wheel Brackets Fit a 2016 Ford F-250 Super Duty Truck
    If the brackets are universal brackets, then they will fit your new Ford vehicle. However, if the brackets are custom brackets designed specifically for your Chevy Silverado, then unfortunately they will not fit the Ford truck. In this case, you will need to replace the brackets with those designed to fit your Ford vehicle. You can tell which kind of brackets you have by looking at their shape (universal brackets will be 4 small L-shaped brackets, 2 on each side). I've attached two images...

  • Is the Demco Hijacker 13K Autoslide 5th Wheel Trailer Hitch An Automatic Slide Hitch
    Yes, the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550041 is an automatic sliding fifth wheel hitch so the hitch head will slide back away from the cab automatically while making sharp turns. Therefore, you won't have to get in and out of the truck to engage the slider. If you want to use this on a 2001 GMC Sierra you'll need the Demco Hijacker Premier Series Above-Bed Base Rails and Universal Install Kit part # DM8552009-71.

  • Fitment of Demco AutoSlide Hitch for 2016 Ford F-150 5.5 Foot Bed
    I can help answer the questions you're having about this Demco AutoSlide 5th Wheel Hitch. Demco designed this 13K Hijacker AutoSlide 5th Wheel Hitch # DM8550040 with the 5-1/2 foot beds in mind. As you turn this hitch will give you an extended distance of 22-1/2 inches, which is crucial to most short bed truck owners when making sharp turns. So, this Demco 5th Wheel Hitch will work great for your 2016 Ford F-150. The Demco AutoSlide # DM8550040 is compatible with industry standard above...

    We do have slider hitches that will fit the very short bed length you have of 5-1/2 foot. For that the Demco part # DM8550040 will be your best option. It can slide 22-1/2 inches which would be what you would need to make a tight turn in your 2007 Chevy Silverado 1500. For a set of fifth wheel rails for your truck you'd then want the part # DM8552009-71 which is confirmed as a fit.

    I do have an option for you to use a 5th wheel hitch in the bed of your 2002 Toyota Tacoma, but unfortunately there are no base rails from Reese that fit your Tacoma since it does not have the 8 foot bed. The instructions for part # RP30035-197 which fit an 8 foot bed specifically say it will only fit the 8 foot bed. 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...

  • Where To Install Rails In Truck Bed Of A 1996 Dodge Ram Short Bed
    Hello Avis. When installing fifth wheel rails in the bed of a 1996 Ram short bed, the rails will be installed so that the fifth wheel hitch head is centered over the rear axle. It is recommended that the King pin be centered over the rear axle, or it can be up to 3" ahead towards the cab of the truck. I have included a screenshot from the instructions to illustrate this. I have also included links below with the instructions for the B&W Rail Kit # BWRVR3200 and the Demco Rail Kit # DM8552009-71...

  • Recommended Fifth Wheel For 2014 GMC Sierra With 5-1/2 Ft Truck Bed
    You sure can tow a fifth wheel trailer with your 2014 Sierra. There are a couple options depending on the weight of your fifth wheel trailer. If your fully-loaded-ready-to-tow trailer weight is under 13,000-lbs, I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch, part # DM8550041. This hitch features 22-1/2 inches of travel so that you can execute tighter turns. The Underbed Rail And Installation Kit for this fifth wheel hitch is part # DM8551005. With this kit installed,...

    For your 2010 GMC Sierra 1500 that has a 5-1/2 foot bed, I recommend going with a fixed 5th-wheel hitch like the Reese # RP30047 and the Custom Base Rail Installation Kit # RP30035. 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. The custom base rails include brackets specifically designed for your truck that will simplify installation. I have attached the installation details and a video...

    There are two ways you can get a fifth wheel hitch on your 2005 Silverado with the 5-1/2 ft bed. You can go with a fixed fifth wheel hitch like the M5 Series, part # RP30928. You will then need to change out the pin box on your trailer and replace it with a Sidewinder that will give you the ability to execute corners. The fifth wheel installation kit I recommend is part # RP50064-58. This is a custom kit and it cuts the installation time in half when compared to using the standard kit...

  • Install Kit for Demco HiJacker 5th Wheel Trailer Hitch on a 2008 GMC Sierra 1500 with 5-1/2 Foot Bed
    There are a couple of Demco HiJacker autoslide 5th wheel trailer hitches. One fits above the bed rails and one fits below the bed rails. The benefit of the below the bed rails is that when the hitch is removed the bed is essentially clear for cargo. I can give you recommendations for both. For above the bed rails you can use either installation kit # DM8552009-71, which is a universal kit that will require drilling to install the frame brackets, or # DM8552013-71, which is a custom kit...

  • Can Curt Fifth Wheel Hitch Fit in Place of Demco Hijacker for 2007 Chevy Silverado
    For your 2007 Chevy Silverado 2500HD Demco has two styles of rail kits available. There an underbed version and an above bed version which is much more popular and most likely what you have. The kit you'd have for your truck would be the part # DM8552009-71 which you can look at to get an idea and compare to what you have. If what you have looks like this then yes a Curt E16 hitch # C16115 would work as it is designed to fit the same rails. If it's an underbed rail kit it would be part...

  • Fifth Wheel Hitch Recommendation for 2004 GMC Sierra 2500 Short Bed
    Since the bed length of your 2004 GMC Sierra is less than 8 feet you will need a slider hitch to allow you to make tight turns without cab interference. My favorite option for that is the 18k rated Demco Hijacker Autoslide part # DM8550034 as it slides automatically as you make tight turns. Then for a rail kit to install the hitch in the bed of your truck you'd want the custom fit rail kit part # DM8552009-71 and you'd be set.

There's only one slider hitch that has a far enough range for as short of a bed as his truck and its the Demco Hijacker 13k part # DM8550040 that can slide 22-1/2 inches.

  • Recommended 5th Wheel Hitch for 2001 Dodge Ram 1500
    To determine the best 5th wheel hitch for your 2001 Dodge Ram 1500, you need the gross vehicle weight rating of your trailer. This will determine the weight rating you need for your 5th wheel hitch. 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...

    For short bed trucks like yours you will need a slider hitch to allow your truck and trailer the clearance needed for sharp corners.

This prevents the hassle of getting out and operating the slider. For a fifth wheel rail kit confirmed to fit your 2001 Dodge Ram you would want the part # DM8552009-71. Timbren suspension kits...

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. The ISR rails allow the hitch to drop into the rails and are pinned to the rails. The SL rails allows the hitch to slide under the lip on the rails.

    Either of the rail kits you referenced would work well in your 2007 Dodge Ram 2500 with an 8 foot bed. You should note that while these rail kits are listed as custom fit kits they will install more like a universal one as the L-brackets are the same as the universal kits. Because of that I would go with the Reese universal rail kit part # RP30035 as it has the best price and would work well with your Curt hitch. I attached an install video for you to check out as well.
