2019 Chevrolet Silverado

I purchased these rails for my 2019 Chevrolet Silverado 1500 with the new body style.

All holes lined up properly and the install was no more exciting than any other rail install I've done on other vehicles.

Some of the mounting hardware was lost by the shipping company but etrailer was quick to fix the shipping companies problem with the proper bag of hardware!

  • Parts Needed To Install A Demco AutoSlide 5th Wheel Hitch In The Bed Of A 2020 Chevy Silverado 1500
    The Demco Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550040 is going to need some rails to mount to in the bed of your 2020 Chevy Silverado. For this I recommend the Demco Premier Series Above-Bed Base Rails and Custom Installation Kit for 5th Wheel Hitches # DM8552034-71. I also recommend installing an in-bed 7-way connection point, like part # 50-97-410 so that you can plug in the 7-way from your trailer.

  • 2024 GMC Sierra 1500 5th Wheel Bracket Options to Fit with a Demco Hijacker 5th Wheel Hitch
    Hey Kevin! The FWH 24PA part number you referenced is actually just the part number for the head. Nevertheless, I have 3 different 5th wheel rail kits that fit your 2024 GMC Sierra 1500 - you just have to choose which one matches up with the rails installed on your Demco Hijacker: - Above-Bed Base Rails # DM8552034-71 - Underbed Rail and Installation Kit # DM8551011 - Base Rails for Demco SL Series 5th Wheel Trailer Hitches # DM8553019-12 Feel free to shoot some photos my way of what...

    The best fifth wheel hitch for a 2020 Chevrolet Silverado 1500 with 5-1/2' bed is the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550040 paired with the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit part # DM8552034-71. The Demco Hijacker has a unique auto-sliding mechanism which will work to provide turning clearance while making sharp turns which would otherwise be an issue due to the short truck bed.

    Yes, the Demco Premier Series Above-Bed Base Rails and Custom Installation Kit # DM8552034-71 is compatible with your 2020 GMC Denali 1500 with Carbon Pro bed. Since you have 5-3/4' listed as your bed length you'll either need to used a fixed hitch and swap out your trailer's pin box for a rotating pin box or use the Demco Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550040 to have enough clearance to fully turn without the cab coming into contact with the nose of the trailer.

  • 2022 Chevy Silverado 1500 LTD Correct 5th Wheel Base Rail Kit
    The Curt Custom 5th Wheel Bracket Kit # C95KR will fit a 2022 Chevy Silverado 1500 LTD with a 6-1/2' or 8' bed but since you have the 5-3/4' bed we need to look at a different solution for you. For your application I recommend going with the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails # RP56015-53 because it will be easier to install than the other options plus it's the only kit that requires absolutely no drilling into the frame of your new truck. This also comes...

    The Curt Universal Fifth Wheel Base Rails with Installation Kit - Carbide Black Finish # C16200 can be used on your 2019 GMC 1500, but it will require drilling into your vehicle frame which isn't a whole lot of fun. At this time they don't have the measurements for the rail locations in your truck bed when using this universal kit. I've attached a photo to assist if you go that route showing that when you put the rails so the Reese Hitch is directly over the rear axle, the rails should...

  • Recommended 5th Wheel Hitch for 2020 GMC Sierra 1500 Short Bed
    The Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550040 is the best option for a 2020 GMC Sierra 1500 (5.5' Bed and 6.5' Bed). The reason for this is because with a short bed truck you need a sliding hitch so the trailer does not hit the vehicle while making tight turns. Most sliding hitches requires you to get in and out of the truck each time to engage the slider but not the Hijacker as the sliding feature is automatic which is a huge added convince. The Hijacker can then...

  • Best 5th Wheel Hitch Option for a 2020 Chevy Silverado 1500 with 5-3/4' Bed
    In order to tow a fifth wheel trailer with a truck that has a 5-3/4' bed like the 2020 Chevrolet Silverado 1500, you'll have to use either a fixed hitch with rotating pin box or you can go with the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550040. The Demco Hijacker provides 22-1/2" of travel which no other hitch does and it has an auto slide feature which means no getting in and out of the cab each time you need to make a sharp turn. I recommend the Demco Hijacker because...

  • 5th Wheel Hitch For A 2022 GMC Sierra 1500 Limited Short Bed
    For your 2022 GMC Sierra 1500 Limited I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550040 with the custom install kit # DM8552034-71. This hitch has a gross towing weight of 13,000lbs, and vertical load limit of 3,250lbs. Additionally, with this being a sliding hitch, you will get 22-1/2" of travel front to back to ensure you have the clearance needed for sharp turns.

    For truck beds that are shorter than 6 feet like on your 2019 Chevy Silverado 1500 with a 5-3/4 foot bed you have two options for towing a fifth wheel trailer and preventing truck cab to trailer nose interference. You can use the Demco Hijacker Autoslide hitch part # DM8550040 as it's only slider hitch that moves back 22-1/2 inches to give you clearance with the install kit part # DM8552034-71 or you could go with a fixed hitch like the # RP30047 and rail kit # RP56015-53 and a Sidewinder...

  • Will Demco Custom Rail Kit for 2019 GMC 1500 Short Bed Fit the Long Bed Too?
    The Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit for 5th Wheel Hitches # DM8552034-71 has not yet been tested on the long bed of the 2019 GMC 1500 to confirm fit. Most of the time the frames are the same for those bracket fits, but they can't officially confirm until they have tested it. I checked around with other manufacturers and Reese confirms the fit of the Outboard rail brackets kit # RP56015-53 for all the bed lengths including the long bed. ...

  • Recommended 5th Wheel Hitch for a 5-3/4 Foot Bed 2021 Chevy Silverado 1500
    Yes, you can install a 5th wheel hitch in the 5-3/4' bed of your 2021 Silverado 1500. However, because of the super short length of your bed you are going to be limited to two options that I have listed below. Option 1 is to use the Demco Autoslide 5th Wheel Trailer Hitch w/ Slider item # DM8550040. This hitch will automatically allow your 5th wheels king pin to move backwards towards your tailgate when you are backing and making turns. This has the most travel amongst all sliding hitches...

  • Recommended Rail Kit for Installing a Hijacker FWH-24PA in a 2021 Chev Silverado 1500
    There were a couple of bases available for the Demco FWH-24P 5th wheel hitch. If you have the one that attaches to industry standard rails, the UL base, you will want the Demco Above-Bed Base Rails and Custom Installation Kit item # DM8552034-71. If yours has the SL base, which required vertical rails, then there isn't a way to reuse this hitch on your 2021 GMC Sierra 1500. You'll need to upgrade to a newer hitch capable of being mounted to industry standard rails. The Demco Premier Series...

  • Weight of Demco Autoslide Versus Reese With Sidewinder On a 2020 Chevy Silverado 1500 5-3/4 Foot Bed
    The Demco Autoslide 5th Wheel Trailer Hitch # DM8550040 is going to weigh 309lbs and the Install Kit # DM8552034-71 is 105lbs. The Reese # RP30047 is going to be a lighter option at 108lbs with Install Kit # RP56015-53 being 103lbs. But do remember the Reese Sidewinder # RP77FR is going to weigh approximately 120lbs more than your standard pin box. So while you loose hitch weight in the truck you are going to have a higher tongue weight.

  • 5TH Wheel Trailer Hitch Options For a 2020 Chevrolet Silverado 1500 With 5-3/4 Foot Bed
    With your 2020 Chevrolet Silverado 1500 with the 5-3/4' short bed there are a couple options. If the 5th wheel you are towing has a pivoting pin box like the Reese Sidewinder # RP77FR then you can use a Reese 5th Wheel Trailer Hitch # RP30047 with the Installation Kit # RP56015-53. Otherwise you will need the Demco Autoslide 5th Wheel Trailer Hitch # DM8550040 with Installation Kit # DM8552034-71.

  • Can 2021 GMC Sierra 1500 5-3/4 foot Carbon Pro Bed Install Fifth Wheel Rail Kit
    Since fifth wheel rails attach and are supported by the frame rails and not the truck bed it is possible to install a fifth wheel rail kit in a truck with a Carbon Pro bed like your 2021 GMC Sierra 1500 that has a 5-3/4 foot bed. Since your truck bed is so short you'd need a slider hitch that slides further back than standard hitches like the Demco Hijacker AutoSlide part # DM8550040 which automatically slides back 22-1/2 as you make tight turns. Most slider hitches move about half that...

  • Can I Pull a 5TH Wheel Trailer With a 2019 Chevrolet Silverado 1500 High Country?
    Since the High Country is only a trim for your 2019 Chevrolet Silverado 1500 you are going to need to verify your exact towing capacity with your local dealer or by checking your owners manual with determining exactly what cab and bed configuration as well as drive and if you have their max tow package. Since some of the 2019 Jayco Eagle HT 5th wheels weigh less than 7,500lbs it is likely you may be able to tow one depending on your capabilities and the model of 5th wheel you select....

    It's possible your older Demco Hijacker Autoslide is compatible with the rail kit part # DM8552034-71 that you referenced but since Demco has made a few different rail designs over the years and your picture doesn't show the mounting tabs you'll want to measure first. The rail kit you mentioned is the industry standard style of fifth wheel rails that are separated by 22 inches. Measure from front to back on the tabs of your hitch and if they are 22 inches apart this is the correct kit for...
