Haven't used this yet, but believe it will be terrific for lifting my Demo 5th wheel hitch to move to another truck. Purchased my Demo hitch also from Etailer.com, they are fast shipping, let you know exactly what you need for your particular vehicle. I would recommend them highly for any of your camper & auto and RVing needs! 739535

2018 Ram 2500

The product was in good order. The install is somewhat difficult. The backside driver and front side passenger is easy to install. The drivers front and rear passenger is the most difficult. It would be helpful if the template was sent with the package so that you could layout the bed and drill everything from the top. Because you can't get to the front drivers side from under the truck. It took me 3 hours to install this product. One last comment is that there are 2 bags of nuts, bolts and bushing but you have to figure out what ones to use. If you know the make and model of the truck why can't the correct bolts and all of the accessories be put in the box. 697145

The Demco slider hitch I purchased with you bed kit is truly a phenomenal piece of equipment. I’ve had many questions about my hitch to which I’d recommend to any and everyone. This is my first fifth wheel and my first experience with pulling a fifth wheel. It’s truly amazing how it operates 629149

  • Demco Hijacker Fifth Wheel Hitch or Pullrite SuperGlide for 2019 Ram 2500
    When comparing the Demco Hijacker and Pullrite SuperGlide for your 2019 Ram 2500, I highly recommend going with the Demco Hijacker for a number of reasons The first reason is the superior jaw system of the Hijacker. As you can see by the accompanying photo, this hitch has a single-piece jaw that wraps completely around the king pin, and has an enhanced connection via a 3/4" solid steel bar that locks into place once the jaw is closed. This reinforced jaw system is what will give you...

  • Best 5th Wheel Hitch Option for 2019 Ram 2500 Mega Cab With 6-1/2 Foot Short Bed
    With clearance being the biggest issue for you, there is one option I highly recommend for a 5th wheel hitch that fits your 2019 Ram 2500 with a 6-1/2 foot bed, the Demco Hijacker Autoslide 5th Wheel Trailer Hitch with Slider # DM8550034. The Hijacker gives you more clearance than any other sliding hitch because of its 14 inches of front-to-back travel; other hitches have between 10 inches and 12 inches of travel. That will give you the most possible clearance for your 2019 Ram, and...

  • How to Determine Height Setting of Demco Hijacker Autoslide 5th Wheel Hitch on 2019 Ram 2500
    The first thing to know is that you'll need to have at least 5 inches to 6 inches of clearance between the top of your bed rails and the bottom of the trailer loft. You'll want to measure from the ground to the top of the bed rails on your 2019 Ram 2500 and then from the ground to the bottom of your trailer loft and the difference will be your clearance. Your Demco Hijacker 5th Wheel Hitch # DM8550034 (18,000 lbs) or # DM8550035 (21,000 lbs) have height settings of 15-1/4 inches, 16-1/2...

  • Can 2019 Ram 2500 with RamBoxes Tow Fifth Wheel Trailer
    There is a way to tow a trailer with your 2019 Ram 2500 short bed that has the RamBox cargo system but you will have to install a Sidewinder pin box on the trailer. Standard pin boxes when turning would contact the bedrails and damage them but with the Sidewinder the pivot point is moved up above the bed rails which prevents contact. Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one. There should be a sticker...

  • Do Fifth Wheel Rails Have A Weight Rating
    Fifth Wheel Rails like Demco Hijacker Premier Series rails part # DM8552025-71 are not rated. What is rated for weight capacity is the hitch that goes on the rails such as the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550035 which is rated for 21,000 lbs. The only way to install the fifth wheel rails is to remove the gooseneck hitch you have installed in your truck because they install in the same spots on the frame.

  • Are Demco Premier Base Rails Compatible with 13K Hijacker for a 2015 Ram 2500
    Yes, the Demco Hijacker Premier Series Above-Bed Base Rails # DM8552025-71 will fit both your 2015 Ram 2500 (6-1/2' or 8' bed) and the 13K Demco Hijacker Autoslide # DM8550040 that you're currently using.

    The things that the 18K Demco Hijacker # DM8550034 and the 18K SuperGlide have in common are that they both offer 14" of travel, they are both automatic sliding 5th wheel hitches, have 2-point pivoting hitch heads, are compatible with industry standard base rails, and they are both rated to tow up to an 18K trailer. Both 5th wheel hitches come with a 5-year limited warranty as well. Although they both have the single-jaw system to lock the king pin into place, the SuperGlide hugs it...

  • Best Fifth Wheel Hitch Recommendation for 2019 Ram 2500 Short Bed
    Hey Jake, so I know there's a lot of hitch options for fifth wheel towing and in general you are correct that cost and quality go hand in hand but to answer your question about what you really need versus what's available let's start with the fact that since you have a short bed truck you do need a slider hitch to provide tight turning clearance so you don't hit the cab of your truck on the nose of your trailer. The Demco Hijacker part # DM8550034 that you referenced is a really great...

  • Fifth Wheel Hitch for a Rotating Kingpin on a Grand Designs Reflection 150 Series Trailer
    Part of your Grand Design Reflections 150's best features is the 90 degree pivoting pin box, and it would be a shame to not use it. You're right in that you don't need to have a sliding hitch given its design. However, you'll want to verify the clearance. I've included a link to our Sidewinder FAQ so you can get a similar idea of its features. Most importantly, in this article is how to calculate the clearance to verify if you need a hitch with offset to make the most of your pivoting...

  • Fifth Wheel Hitch Recommendation for 2018 Ram 2500 With Short Bed
    The hitch I recommend for a 2018 Ram 2500 short bed without the fifth wheel prep package is the Demco Hijacker Autoslide # DM8550034 because it utilizes an autoslide so you never have to get out of your Ram in order to slide the hitch like you do with other sliding fifth wheels. The Hijacker has a head which rotates up to 90 degrees with your trailer, a single-piece jaw which gives you 360 degrees of contact with your king pin and is made in the United States of America. The base rails...

  • Recommended Equipment Needed to Tow a 16,000 lb 5th Wheel with a 2016 Diesel Ram 2500
    To figure out how heavy of a trailer you can tow with your 2016 Dodge Ram 2500 take the GCWR of your Ram (25,300 lbs) and subtract the Curb Weight of your Ram (7,620). This leaves you with 17,680 lbs of weight for any extra things on your truck like a 5th wheel hitch as well as passengers, luggage, your trailer, plus any tanks on your trailer. If the trailer that you are looking at has a dry weight rating of 12,650 lbs then that leaves you with 5,030 lbs for passengers, luggage, 5th...

    Trailair Air Ride 5th Wheel Pin Box # LC158778 is fully compatible with Demco Hijacker hitches such as the 18K # DM8550034 and 21K # DM8550035 which fit short beds fitted with standard above-bed base rails like Demco kit # DM8552025-71. You'll also want to use the Demco Capture Plates for Trailair Pin boxes # DM6171. Pin box part # LC158778 is a correct fit to replace a Lippert 1621HD 5th wheel pin box.

  • Best Slider Hitch Recommendation for a 2016 Ram 2500 Short Bed
    We have just what you would need. Since you have a short bed truck you would need a slider hitch to allow you to make tight turns without trailer/cab interference. My favorite slider hitch is the Demco Hijacker that automatically slides when you are going around tight corners. For that you would want the part # DM8550034 for an 18k hitch or part # DM8550035 for a 21k hitch. Then for rails you would want the custom install kit part # DM8552025-71 that will minimize drilling and install...

  • Can 2019 Ram 2500 Power Wagon Tow a Fifth Wheel Trailer or is 2019 Ram 2500 Diesel Better Option
    A 2019 Ram 2500 Power Wagon is really built as an off-road type of truck, though there isn't any reason you can't tow a fifth wheel trailer with this truck. The issue with this, when compared to a standard 2500 diesel is that the 2019 Power Wagon only comes in a 6'4" bed, so you would need a sliding fifth wheel hitch. If you do go this route the best option by far is the Demco Hijacker Autoslide because you never have to get out of your truck just to make a turn like you do with a standard...

  • Recommended Air Helper Springs for 2016 Ram 2500 Towing Heavy 5th Wheel Trailer
    The Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs # F2706 referenced in your question are confirmed to fit your 2016 Ram 2500. These heavy duty air springs feature a 7,500 pound capacity, but they will not actually increase the payload capacity of your truck. This is really the case with any aftermarket suspension enhancement system. What this system will do, however, is equip your Ram to better handle weights within its capacity.

    Let's start with a 5th wheel hitch for your truck. For a short box truck like your 6-foot-bed 2014 Ram 2500 you'll need a sliding 5th wheel. I recommend a round tube slider with the greatest amount of slider travel to give you the most turning clearance. Demco's 18K slider # DM8550034 offers 14-inches of travel and works with their custom base rail install kit # DM8552025-71. For a 5th wheel wiring harness use part # PK11893-11932.

  • Will Andersen Ultimate Allow a 90 Degree Turn When Towing with a 2017 Ram 2500 6-1/2 Bed
    The Andersen Ultimate Connection # AM3200 has a 9" offset. I am not sure if it will allow you to make 90 degree turns with your 2017 Ram 2500 6-1/2' bed but this can simply be determined by measuring from the back of your cab to the middle of the space in-between your base rails (or the pucks). Once you know that simply add 9" for the offset and the subtract half of the width of your trailer. The formula looks likes this: (A + B) - C = Clearance A = Distance from center of fifth wheel...

    I looked up the BDS lift kit and it is a suspension lift which is good because that means the truck bed and frame are still the same distance apart from each other so you can install a hitch in the bed. If towing a 5th wheel trailer you will want a 5th wheel hitch but given your situation I do have a recommendation that will work as long as the 5th wheel trailer has the tapered front end for short bed trucks and as long as it has a pin box that is compatible with a Reese Goose Box.
