This hitch takes care of tight turns automatically. The built-in rack-and-pinion gear system slides the hitch head up to 14" toward the tailgate whenever you turn at slow speed, giving you the space you need between the cab and trailer. When you straighten out, it slides itself back into towing position. There’s no lever pulling or climbing in and out—just smooth, controlled movement that makes maneuvering around campsites or parking lots simple.
The wraparound, single-piece jaw design gives you full 360-degree contact around the trailer’s king pin for a tight, secure connection. A 3/4" thick solid steel locking bar reinforces the latch, automatically locking when the jaw closes. This setup cuts down on rattle and chucking so the ride feels stable and quiet mile after mile.

Hooking up feels easier thanks to the double-pivot head that moves both front-to-back and side-to-side. It adjusts naturally as your pin box meets the hitch for a smoother connection. Three polyurethane dampeners inside the head help absorb road shock and reduce towing noise, keeping things calm over rough pavement or uneven campsites.

You can dial in the right fit with three height positions—15-1/4", 16-1/2", or 18"—so your trailer stays level and maintains proper bed rail clearance. The side plates bolt directly to the base for easy adjustment, giving you flexibility to match different trailer setups without extra parts.
Rated for 21,000 lbs gross towing weight and a 5,250 lbs vertical load limit, this all-steel hitch is built to handle serious fifth wheels. The rust-resistant black powder coat finish stands up to weather and use, while the diamond-plate tread on the base adds a tough look that matches its strength.

This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.

Today we're going to take a look at the Demco Hijacker Premier Series Custom Mounting Brackets for Fifth Wheel Above-Bed Base Rails. This is a custom-fit part. It is designed to fit the 2011 and newer Ford F-250, F-350, and F-450 Super Duty trucks with either the 6 3/4 foot truck bed, or the 8-foot bed without the factory rail kit. Now on any custom-fit part I always like to recommend for you to go to our website, use our fit guide, put in your year and model vehicle, and it'll show you if this part will work for your application. Now these installation brackets will mount beneath your truck bed to provide attachment points for your Fifth Wheel rails to attach to. Now the base rails we do sell separately on our website.
It's part number DM6071. The rails is what sits in your truck bed and allows the installation of the Fifth Wheel hitch to the truck. Now these are custom-fit brackets. They mount to the outside of the frame using existing holes in your vehicle's frame. Because of that they minimize drilling, reduces installation time, and they're designed to avoid known obstacles that are along your specific vehicle's frame. Notice they have a tag on each side.
Driver's it says here, passenger here, so it helps you know what position these go in. Now these parts are a sturdy steel construction, have a nice black powder coat finish to help resist corrosion. All the hardware to install them is included. It comes with a nice set of detailed instructions that'll describe how to install it. It even has pictures to show you how to install it.
These parts are made in the USA, but that should do it for the review on the Demco Hijacker Premier Series Custom Mounting Brackets for Fifth Wheel Above-Bed Base Rails.

Thank you for the review! While I do see where a hole in the mounting bracket would make this easier to remove with your Adapter Plate # DM6333, a solid bracket in this instance is much better for strength, especially considering this hitch is designed around the universal rails for trucks.

In the description it says locking plates, sold separately, are required for the Rota-Flex Pin box that you have. Item # DM6171

I firmly believe that every fifth sold should have one of these hitches. It is a job getting it in and out of truck but I feel better knowing its not going to let my trailer damage my truck.

After about 6000 miles the hitch developed some fore and aft movement. After another 2000 miles it seemed to be excessive with a loud clunk when stopping and starting. Yes, I do grease it as per instructions before each trip. I called Demco and told them the problem and they sent me the parts I needed at no charge since it was under warranty. Since I had the mechanical ability I disassembled, diagnosed and repaired it myself. I thought later on that I should have been compensated something for my time only because if I took it to a dealer they would have charged for labor. Just a suggestion, there needs to be an easier way to lubricate this hitch rather than removing the large pivot pin and also the large pivot bolt and greasing them by hand. Some well placed grease fittings would make this job a lot easier and cleaner, especially when on the road. Also, the hitch owner would be far more inclined to do it. Other than that the hitch has performed great and I am very happy with it. Thanks.
