Secure Wraparound Jaw with Locking Bar

Wraparound Jaw

The single-piece, strong wraparound jaw completely surrounds your trailer's king pin for 360 degrees of contact. This wraparound jaw provides a more secure connection than standard 2-piece jaws that close in on the king pin from the sides. The increased jaw-to-king-pin contact on the UMS hitch offers tighter tolerances around the king pin, which minimizes both rattle and chucking, for a smooth, quiet ride.


A 3/4" thick solid steel locking bar spans the area in front of the jaw. This bar provides an added barrier of protection against accidental disconnection so you can have peace of mind that your trailer is secure. The locking bar is attached to the jaw and to the spring-loaded handle. The bar automatically locks when the jaw closes around your king pin


Double-Pivot, Cushioned Hitch Head

Double Pivoting Head

The double pivoting, cushioned head improves your towing experience dramatically by helping to reduce jarring and unwanted noise. Built-in pins allow the hitch head to pivot back and forth and side to side. And hookup is easy because the hitch head will automatically pivot to the proper angle when it comes into contact with your pin box.


Dampeners

Three polyurethane dampeners help to cushion the movement from the pivoting head and to reduce towing noise. Two of these dampeners are built into the head assembly to cushion the head's side-to-side pivoting. The third dampener cushions the back-and-forth motion and must be installed in the hitch prior to use. Installation of this third dampener is easy - simply press the dampener up into the pre-drilled hole underneath the hitch head.


Easy Installation and Simple Removal for Full Bed Access

This UMS Double Pivot hitch is specially designed to fit in the underbed rails of your Ford Super Duty factory fifth-wheel towing prep package. To assemble the hitch, all you have to do is bolt on the side plates and attach the head to the hitch base.


The side plates have 2 functions. They contain the feet that fit into your OEM tow package receivers, and they allow you to raise or lower the hitch head to better match your pin box height. After you choose your desired height setting, simply bolt the side plates to the hitch base with the included hardware. Then lower the hitch into the 4 puck receivers in your truck bed. Turn the handles to lock the feet into the pucks and secure the handles with the included safety pins. The hitch can be removed to give you full truck bed access. Simply remove the safety pins, turn the handles to unlock the feet, and lift the hitch out of the receivers.

Awesome Price! Great Hitch! Great Company to deal with.
Thank You!



by:

My son and I installed it, Works great! Thanks



by:

Fits perfectly, tows well. No issues after 10k miles or more.



by:

The unit came in pieces, and was easy to assemble. There was some minor trouble in placing it into the puck holes in the bed, but it works great and is easy to hook up and un-hook.



by:

This product is so good I purchased 4 more for my other Chevrolet Silverado's 3500s



by:

Haven’t towed anything yet waiting on new trailer. Ordering and service was the best!!! Followed through right to delivery.



by:

Hitch appears to be well-constructed and sturdy. I have not yet installed it. Some assembly is required, and the instructions aren't crystal clear. Better illustrations would be helpful. The videos online are the best source of installation information. Shipping materials lack protection. The powder coating was damaged in a few locations, as well as the instructions. I expect the hitch will operate exactly as designed a long as I protect the exposed parts from the inevitable elements. Rubber grommets would be a nice addition to the holes drilled in the truck bed.



by:

Another excellent product from etrailer. Already used it once and it worked great. Wouldn't go anywhere else for my towing needs.



by:

Fit perfectly and works great!



by:

Not to difficult to install. It will require 2 people to get the bolts torqued down. Handles a 14000 lb fifth wheel with ease



by:

I haven't towed with this hitch yet so I'll update this when I do. Shipping was faster than I expected. It shipped in two boxes and both arrived at the same time and in good shape. Assembly took about an hour and was pretty straight forward. The included instructions are a bit vague but if you have just a little bit of mechanical knowledge and some tools its easy to figure out. I couldn't find any torque specs in the instructions but after doing a little research on the internet I found there isn't an actual spec, only make sure the bolts are good and tight, but not overly tight.



by:

Have pull our 42' Montana 5th wheel trailer a few times and this hitch is working great.



by:

No chucking at all, easy assembly and maintenance. Drops in and out of the brackets easily and the latching handles double as carry handles. Weights a lot, and comes in multiple boxes, so be sure to tip your UPS guy!

The bolts are all grade-5 hardware and torque should be standard based on diameter.
