Video Transcript for Demco Fifth Wheel Installation Kit - Custom - DM8552012-71 Review

Today we're going to take a look at the Demco Hijacker Premier Series above bed base rails and the custom installation kit for fifth wheel hitches. Now this is a custom fit part. It is designed to fit the 2001 to 2010 Chevrolet Silverado and GMC Sierra 2500 and 3500 Heavy Duty Series trucks with either the six and a half foot bed or the eight foot bed. Now on any custom fit part what I like to recommend is to go to our website, use our fit guide. Put in your year and model vehicle and it will show you if this will work on your application. This installation kit will let you mount your Demco Hijacker Premier Series fifth wheel trailer hitch in the bed of your truck. The rails right here, they are also compatible with above bed fifth wheel trailer hitches by BMW, Curt, Draw-Tite, Hidden Hitch, Husky, Reese and Valley.

The base rails is what will provide the necessary mounting points for your fifth wheel hitch. The mounting brackets right here, these will install beneath the truck bed and they provide the attachment points for the above bed base rails to connect to. These are custom fit brackets. They mount to the frame using existing holes in your vehicle's frame. This will help minimize drilling, reduces installation time, and it's designed to avoid any known obstacles along your specific vehicle's frame. These parts are a sturdy steel construction with a black powder coat finish to help resist corrosion.

This part will include everything shown here: the two base rails, the two mounting brackets, all the installation hardware, some spacers, some shims, fish wire, everything you need to install this, even a nice set of detailed instructions that will describe how to install everything with pictures. These parts are made in the USA. There's your two side mounting brackets and there's your two base rails. But that should do it for the review on the Demco Hijacker premier series above bed base rails and custom installation kit for fifth wheel hitches.

  • Recommendation For 5th Wheel Hitch For 2009 Chevrolet Silverado HD
    Depending on the total loaded weight of the fifth wheel you get, your 2009 Chevrolet Silverado 2500 HD should work for you. I did some research and found that GM has given the 2500 HD a maximum fifth wheel towing capacity of 16,700-lbs. What exactly are your limits will be determined by your vehicle model. Make sure to check your owner's manual for capacities and recommendations. If you have a 6-1/2 foot bed, I recommend the Demco Fifth Wheel Sliding Hitch, Item # DM8550034. You...

  • Demco 5th Wheel Installation Kits for 2005 Chevy Silverado 2500
    If your 2005 Silverado 2500 is a 6-1/2 foot bed you can use Demco 5th wheel universal installation kit # DM8552009-71 if you have the Premier Series 16K hitch # DM6076P-UL-16K, or custom install kit # DM8553004-12 if you have the Hijacker SL Series hitch # DM6076SL-16K. The part # DM8553004 that you referenced is just the frame brackets for the SL. If your Silverado 2500 is a long bed use either universal install kit # DM8552009-71 or for a shorter install time the custom install kit...

  • Fifth Wheel Trailer Hitch Recommendation for 2008 Chevy Silverado 2500HD Short Bed
    Since your truck has a short bed you have to go with a slider hitch to give you the needed clearance to make tight turns. Otherwise the corners of the front of the trailer will hit the cab of your truck around tight turns. Because using a slider hitch can be a bit of a hassle I really like the Demco Hijacker part # DM8550034 which automatically slides back as you make tight turns so you never have to worry about it. Then for a custom rail kit designed to minimize drilling and install...

  • Recommended 20K 5th Wheel for a 2008 Chevrolet 2500HD CrewCab with 6-1/2 Foot Bed
    I recommend the Pro Series # PS30121. I recommend the custom installation kit # RP50064-58 for the Titan 20K 5th Wheel hitch. This kit requires no drilling for the frame brackets and will therefore take less time to install on your truck. The Titan hitch will have 11 inches of travel and have a tongue weight of 5,000lbs and a gross towing weight of 20,000lbs. The dual-jaw system provides more jaw-to-king-pin contact than traditional dual-jaw hitches and its geared teeth ensure an...

  • Auto Slider Fifth Wheel Hitch Recommendation for Short Bed 2007 GMC Sierra 2500HD
    Since you have a short bed you'd immediately need to rule out the Andersen Ultimate unless the trailer has a tapered nose as it won't give you enough offset for turning clearance. Since you'll need a slider hitch in your truck bed I'd recommend an auto slider like the Demco Hijacker Autoslide part # DM8550034. Having to get out and operate the slider every time you enter or leave a parking lot would be a hassle and inconvenient. The auto slider hitches make it so that you don't have to...

  • Demco Autoslide Fifth Wheel Hitch Recommendation for 2007 GMC Sierra that Can Also Tow Gooseneck
    We have just what you would need. To install a Demco Hijacker AutoSlide hitch you would instead need the hitch for industry standard rails part # DM8550035 and then for the rail kit to fit your 2007 GMC Sierra you would need the part # DM8552012-71. Once installed you would have the option to either use the fifth wheel hitch or the gooseneck adapter part # DM5996.

  • Demco Hijacker Autoslide 5th Wheel Hitch Options for a 2006 Chevy Silverado with a Short Bed
    We do have Demco Autosliding 5th wheel hitches for your 2006 Chevy Silverado with the short bed but the Demco Hijacker # DM8550038 that you referenced is designed to fit the unique puck system found on Ford pickups. For a 1500 that is not a Flareside or Stepside then you can use the Universal Base Rail Kit # DM8552009-71 to use the 18K # DM8550034 or 21K # DM8550035 Demco Hijacker. This kit does require drilling. If you happen to have a 2500 instead then I recommend using the Custom...
