Replace the side plate assemblies that came with your Demco Autoslide underbed 5th-wheel trailer hitch (DM8550041, DM8550022 or DM855037). Bolts onto the hitch base so that you can attach your hitch to the underbed mounts in your truck.

Today we're going to take a look at the replacement side plates for the Demco Hijacker Autoslide fifth wheel trailer hitches, and this is for the underbed mount. Now this will replace the side plates that came standard with your Demco Hijacker Autoslide underbed fifth wheel trailer hitch. They are designed to bolt onto your hitch base so that you can attach your hitch to the custom underbed rails. This is designed to fit the 13,000 pound Hijacker, Part Number DM8550041. It also fits the 18,000 pound Hijacker, DM8550022, and the 21,000 pound Hijacker, DM8550037 models. This is a simple bolt-on installation to your hitch base. There are multiple rows of bolt holes on these side plates and on your hitch base, so depending how you line them out, it will let you adjust the hitch height.
The hitch height settings will go from either 15-1/2 inches to 16-3/4 and 18-1/4, so you have your choice of those three settings to get your trailer and tow vehicle as level as possible. These do have a rust-resistant black powder coat finish. They are an all-steel construction. It does include the instructions. It will include the mounting hardware, and it also includes two 1/4-inch spacers and two 3/8-inch spacers, and the spacers are used for adjusting your hitch mount with the bed pockets of your truck, and this part is made in the U.S.A. The way that these would open up is you just pull the clip, pull the pin out, and you can see each one of these will rotate out, and when you rotate those out, it will let you drop it into your underbed mount, and then once there, you just turn this back in to lock it, and then put your clip right through there just like that. This part is made in the U.S.A. That should do it for the review of the replacement side plates for Demco Hijacker Autoslide fifth wheel trailer hitches with the underbed mount..

I want to start by saying your customer service was exceptional!! Well I should say the first guy I talked to was not good and had no idea of what has going on but the next 3 were great! I ordered the unit with the recommended Side Rail. They wouldn't work and had to wait for the right ones. That said. The unit is very well designed and constructed! The installation was a bit tricky. I was installing the unit at its lowest setting. One issue was the installation of the steel spacers (1463-76 &14959-76) to get the proper fit I had to remove the small tabs that were welded to the side of the autoslide unit. Second issue was installing the (outrigger bar 6018) With the bar in place the UMS pins would not turn to the lock position, the bar was holding the unit too high up. I used one of unused spacers (14959-76) in its place, it worked perfect. We took the 5th wheel out last week (I go to very remote locations in the mountains of Colorado) the unit worked great!
Package arrived as per date promised. Other than a few scuffs on the outer box, everything looks good. The two items were separately packaged, giving the shipment an extra degree of protection.
I will be installing my new under body 5th wheel hitch this weekend, and I expect it to go “without a hitch”
This was the best solution for my Dodge RAM 2500 towing my Alliance 340RL 38' 5th Wheel. My son helped me install the rails under the bed and now it is very easy to remove the hitch when I am not using it. It is very strong and I highly recommend this for anyone with a short bed truck.
The Demco product works well and deserves five stars. etrailer originally sent me clearly used scratched and greased parts at the new parts price. After contacting etrailer they had me box up and ship back the used items and sent me the new items that worked fine. When I pay full price, I expect new items. I will gladly pay more elsewhere to avoid using etrailer again.
One of the best hitches. Handles the trailer with ease. Excellent purchase and has made towing our 42 ft toyhauler much easier. Great product. Thank you
This was the brackets needed to install the Demco underbed Hijacker fifth wheel hitch on my Dodge RAm 2500. Perfect fit, fast ship, package arrived without any damage. Great service from ETrailer
Very well made. Fit directly into my new truck under bed mounts. Now I can get rid of the adapter system. This allows the fifth wheel hitch to be set at the proper height. (would not go low enough with the adapter in place)
Great shipping - double boxed.
Installation just as described in instructions.
Great fit,heavy duty parts.
