Ask the Experts about this Demco Fifth Wheel Installation Kit

  • Position of Demco HiJacker Auto Sliding 5th Wheel Hitch in a 2015 Chevy Silverado 2500 Short Bed
    Demco does not provide measurements for rail placement for installation kit # DM8552011-71 for your 2015 Chevy Silverado 2500 but what they do say is that the hitch can be centered over the center of the rear axle up to 3 inches forward. On a short bed truck you will want it as far back as you can so centered over the axle is a good place for the hitch. Now, from the center of the hitch forward on the truck to the front of the rail will be approximately 14 inches. So you would measure...

  • Recommended 5th Wheel Hitch for 2016 GMC Sierra 2500 with 6-1/2 Foot Bed.
    The 5th wheel hitch I recommend for your 2016 GMC Sierra 2500 HD Denali is the Demco Hijacker Autoslide, , 21K # DM8550035. For the 18K hitch you would want part # DM8550034. The rail kit for your truck that is compatible with the Hijacker Autoslide is # DM8552011-71. This sliding 5th wheel hitch will provide the room needed for you to make sharp turns while towing your 5th wheel with your 6-1/2 foot bed truck.

  • Sliding Fifth Wheel Hitch Recommendation for 2018 GMC Sierra 2500 Short Bed
    For a sliding fifth wheel hitch for your 2018 GMC Sierra 2500 short bed without the factory rail kit the best option is the Demco Hijacker Autoslide part # DM8550034 as it will slide automatically as you make tight turns. Then for a rail kit that is confirmed as a fit for your truck you'd want a custom install kit part # DM8552011-71 which is going to minimize drilling and install time on your 2018 GMC Sierra 2500 when compared to a universal kit.

  • Install Kit for Old Demco FWH 24P 5th Wheel Hitch for a 2011 Chevy Silverado 2500 Short Bed
    Check the legs/base of your hitch. If it indicates Ultra or UL then you can use installation kit # DM8552011-71 on your 2011 Chevy Silverado 2500 short bed. If it shows SL then you would instead use # DM8553007-12. If there is no indication send some pictures of the legs/base so I can see how it attaches to the rails.

  • Demco Fifth Wheel Rail Kit Recommendatino for 2016 2500 Chevy Silverado Short Bed
    The 2016 Chevy Silverado 2500 came with two bed length options. 8 foot and 6-1/2 foot. If yours seems to be a 6 foot bed that would mean it would fall in the 6-1/2 foot bed range which is what the part # DM8552011-71 is designed to fit. I attached an install video as well. For a sliding fifth wheel hitch to fit these rails to allow you turning clearance the Demco Hijacker part # DM8550035 would be your best option. It automatically slides as you make tight turns to give you the needed...

  • Recommended Demco Hijacker Autoslide Compatible with 2012 GMC Sierra and 2021 GMC Sierra
    I have a solution for you, but Demco does not make a hitch that will drop directly into the pucks on a GMC truck, so you would have to use an adapter on the new truck. For the hitch, you can use the Demco Hijacker Autoslide # DM8550035; this hitch has a 21k capacity and will fit into industry standard base rails or the adapter mentioned below. I think it's always a good bet to go up to a higher capacity if there's a chance that you might end up with a trailer that's higher weight; so if...

  • Can Demco Hijacker Autoslide Fit Reese Fifth Wheel Rails for 2017 Chevy Silverado 2500
    Yes, the vast majority of the fifth wheel rail manufacturers make them all to the same "industry standard" design which is what the Hijacker Autoslide part # DM8550034 is designed to fit. We have a Demco set of custom rails that fit your truck with the part # DM8552011-71 but if you wanted to use a Reese custom rail kit you could too and for that you'd need # RP50066-58 and you'd be set.

  • Recommended 5th Wheel Hitch for 2015 Chevy Silverado 2500HD Dual Cab with 6-1/2-Foot Bed
    Pulling a 5th wheel trailer with your short bed 2015 Silverado 2500HD will require a sliding type 5th wheel hitch in order for you to have enough clearance for making tight turns. Most slider hitches require you to get out of the truck to release the slider mechanism before you can finish your maneuvering, but we have Demco's Hijacker automatic 5th wheel hitches that save you that hassle. Their 18K model # DM8550034 and their 21K model # DM8550037 both give you a full 14-inches of slider...

  • Can Demco Hijacker Autoslide Hitch be Used on Long Bed Chevy Silverado
    Although a sliding hitch isn't needed on a long bed truck since you don't have to worry about cab clearance, there is no reason one like the Demco Hijacker Autoslide # DM8550034 can't be used on your 2018 Chevy Silverado 3500. It will still work great on your new truck to provide you with an excellent connection with the trailer and an 18,000 pound towing weight capacity. If your new Silverado is equipped with the factory puck system you will also need to add the Rail Adapter # DM6206,...

  • Can Trailer Be Disconnected At Angle With Demco Autoslide 5th Wheel Hitch On 2015 GMC Sierra
    We do have an Autoslide fifth wheel hitch that may work for you. It is the Demco Hijacker, part # DM8550034. I called my contact at Demco and asked about disconnecting and the angle it can be detached. They told me that there is a 10 degree angle that the trailer can be disconnected to with the Autoslide. Since the opening that the king pin slides into has a limited amount of movement, trying to detach the trailer at a sharper angle would not work. With the Autoslide you have an additional...

  • Fifth Wheel Hitch Recommendation For 2016 Chevrolet Silverado With Factory Tow Package
    I would love to tell you that we have a sliding fifth wheel hitch that will work with the puck system on your 2016 Silverado but unfortunately there is none available. I spoke with my contact at Curt and they are in the process of designing a system but it is not near production yet. Based on the dimensions of your truck and the trailer you can probably execute about 50 degree turns with a stationary fifth wheel hitch. That can be tough and can cause a lot of issues if a shorter turn is...

  • Demco Hijacker Autoslide Fifth Wheel Hitch Recommendation for 2018 GMC Sierra 2500
    For your 2018 GMC Sierra 2500HD short bed without the hitch prep package you'd want the Demco Hijacker Autoslide part # DM8550034 and then for the custom rail kit that fits your truck you'd want the part # DM8552011-71 which is custom fit for your truck. Custom rail kits install much quicker than universal rail kits and minimize drilling. I attached an install video for this rail kit in a similar 2016 GMC Sierra 2500 for you to check out as well.

  • 5th Wheel Hitch Options for a 2015 GMC Sierra 2500 Denali
    Since your 2015 GMC 2500 has the 6-1/2 foot bed you will want to go with a sliding 5th wheel hitch. There are a couple of different options that you can go with here. If you are wanting to go with a 5th wheel hitch that uses the standard base rails then I recommend going with the Reese 20K # RP30083 along with Base Rails Kit # RP50066-58. This 5th wheel hitch is one of the best hitches that we currently carry due to the single-jaw system and 4-way pivoting head to help secure the king...

  • Fifth Wheel Hitch Height for 2017 Chevy Silverado 3500 With 21-3/8 Inch Sides on Bed
    In order to determine the correct hitch and height settings, you will need to take a couple quick measurements. Start by parking both your 2017 Chevy Silverado 3500 and new fifth wheel on level ground. You will then measure from the plate of the pin box to the ground. After that measure from the bed floor of your Silverado to the ground. The difference between these two measurements is the height of the hitch you'll need, keeping in mind you are going to need to keep your trailer level...

  • How Easy is it to Remove Demco Hijacker Autosliding Fifth Wheel Trailer Hitch from Truck
    The Demco Hijacker Autoslide Fifth Wheel Trailer Hitch # DM8550034 installs onto industry standard rails. The only issue with removing the hitch from your truck is that it's heavy. The head itself is approximately 40 pounds and base is around 200 pounds. So the issue with removal is strictly weight. To install the Hijacker in your 2016 GMC 2500 you can use the Installation Kit # DM8552011-71. Also, if you'd like to install a 7-way connector inside the bed of your truck to make it...

  • 5th Wheel Towing Capacity and Hitch Recommendations for a 2016 GMC Sierra 2500HD Short Bed
    The dry hitch weight, also called tongue weight for travel trailers or pin weight for 5th wheel trailers, is the amount of weight pushing down on the trailer hitch. Dry means the trailer is empty; no cargo, water, propane, just the trailer by itself. So the dry weight is less important than the actual hitch/tongue/pin weight when the trailer is loaded and ready to tow. Based on the figures you have provided the trailer has a hitch weight that is 21 percent of the gross trailer weight...

  • Recommended 5th Wheel Hitch for 2012 GMC Sierra 2500HD 4x4 with 6-1/2-ft Bed
    Sliding 5th wheel hitches are recommended for towing with a short-bed pickup like your 2012 GMC Sierra 2500 HD Series with 6-1/2-foot bed. Sliding hitches from B&W and Demco are the ones I most often recommend because of their build quality (both are made here in the USA). Their products cost more because they are worth more. They are beautifully made products that inspire confidence, potential sticker shock notwithstanding. Although you state your trailer will not ever be loaded up...

  • Compatibility of Demco Recon Fifth Wheel Trailer Hitch with Revolution or Sidewinder Pin Box
    You are correct that the Curt Q Series fifth wheel hitches, like # C16245, are not compatible with a Sidewinder or Revolution pin box because the spherical axial bearing that allows the pivoting of the hitch head. The Demco Recon # DM8550043 that you purchased does not have this issue and will work great with a Sidewinder or Revolution. For the install kit into your 2012 GMC Sierra you'll want # DM8552011-71.

    The manufacturer of the truck is always the final authority on the towing capacities.

You can try contacting a dealer local to you with your VIN for even further clarification. Since you have a short bed truck you are going to need a slider hitch.

  • Best Sliding Fifth Wheel Hitch for 2016 Chevy 2500 Silverado with 6 1/2 bed
    Auto slide hitches are the way to go for a short bed truck since they don't force you to get out and activate them. They are going to be heavy since there is a lot of moving parts which have to be rated for the towing capacity. That being said the Demco Hitch part # DM8550022 can be installed an removed in sections which allows for a lighter weight install removal. Your Bed Rug will need to be trimmed for any fifth wheel hitch rail kits. The rail kit to use with this hitch is the # DM8552011-71...
