  • Installation Location of Demco SL Rails in 2003 Chevy Silverado
    The Custom Installation Kit w/ Base Rails for Demco Hijacker SL Series 5th Wheel Trailer Hitches # DM8553004-12 are installed 20-3/4 inches from the rear of the box. The instructions don't specify the measurements from the side of the box, but the mounting brackets ensure the locations are correct on the sides which are attached directly to the truck frame rail.

    Custom Base Rails and Installation Kit for Demco Hijacker SL Series 5th Wheel Trailer Hitches Item # DM8553004-12 is not a fit for your 2017 GMC Sierra 1500.

  • Compatibility of Demco AutoSlide 5th Wheel Hitch with Valley Above-Bed Base Rails
    For a Demco 18K Hijacker Autoslide hitch that fits into your Valley industry-standard base rails you'll use part # DM8550034 which is shown in the linked video. You will need a locking plate; use part # DM6026 if you have a standard 5th Airborne pin box; use part # DM6062 if you have an extended type pin box. If you need a wiring harness you can use part # DM8555002 which plugs right in to your existing bumper-mounted 7-way.

  • Fifth Wheel SL Rail Bracket Kit Recommendation for a 2013 Chevy Silverado 1500
    From looking at the picture you sent in it looks like you have a set of the SL Demco fifth wheel rails with an older Demco stationary hitch. For a bracket kit to install the rails in your truck bed you would want the part # DM8553004. With this and your rails you would basically have a # DM8553004-12.

  • Fifth Wheel Hitch Recommendation for Flat Bed Truck
    The thing about flat bed trucks is that they have a much taller bed than a standard truck bed so you end up having to go with a hitch that sits a bit lower to compensate for that like the Demco Hijacker SL Series Flat Deck 5th Wheel Trailer Hitch # DM6076SL-FLAT. A standard fifth wheel hitch like the Curt part # C16181 that you referenced will sit too tall and won't allow your trailer to sit level. The other thing to consider is the length of the bed. Some flat bed trucks have beds...

  • 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...

  • Availability of Fifth Wheel Hitch to Fit Older Style Fifth Wheel Rails that Run Parallel to Frame

It sounds like you are looking for a hitch to attach directly to your parallel fifth wheel rails as well as get a gooseneck adapter like part # DM5992.

  • Mounting Brackets For Older Model Hijacker 5th Wheel
    I contacted Demco directly. It's not as simple an answer as I'd like but really depends on what you have. The FWH-24P is the part number of hitch head only. That hitch head was used on 2 different series of 5th wheel hitches. This would have been manufactured by the former owner of the Demco line in Canada. They had 2 series of hitches one was the SL series and the rails ran front to back in the truck bed. The other line of hitches was a UL Series and those run side to side in...

    The rail kit # DM6014 that you referenced will fit your older Demco 5th wheel hitch if it uses base rails that run side to side. To mount these rails to your 2001 GMC Sierra 2500HD with the 6-1/2' bed you need the Universal Mounting Brackets # DM8552009 which require drilling into the frame or the Custom Mounting Brackets # DM8552012 which install in pre-existing holes in your frame so no drilling is required.

  • Installation Kit for Demco HiJacker SL Flat Deck Hitch in a 2008 Chevy Silverado 2500 Short Bed
    In order to use the Demco 5th wheel trailer hitch # DM6076SL-FLAT you will need the proper installation kit for your 2008 Chevy Silverado 2500 short bed. The correct kit for the hitch and your truck is # DM8553004-12. I also recommend installing a 7-Way trailer connector in the bed of the truck to make hooking up easier without the need for any extensions. You can use # 41157.
