WARNING: Cancer and Reproductive Harm -

What if there was a hitch ball mount that eliminated the need for all other ball mounts? Whichever trailer you wanted to tow, this universal ball mount could be adapted to fit the job. Imagine never having to buy another ball mount for your hitch ever again. Sound too good to be true? With the CURT adjustable channel mount, that's exactly what you get.

The adjustable channel mount is a highly versatile hitch ball mount option. It features a standard receiver hitch shank, a multi-level channel and a standardized trailer ball attachment, allowing you to easily tow various types of trailer without requiring you to keep an arsenal of ball mounts on hand. It also features a highly durable construction built to withstand the elements, and built-in anti-rattle features for smooth, quiet towing.

The dual-ball head of this channel mount offers versatile towing options. It features standard 2" and 2-5/16" diameter trailer balls to fit two different size trailer couplers. The entire head securely attaches to the adjustable shank using the included hitch pins and clips, and these hitch pins can also be replaced with a hitch lock set for additional security.

This adjustable channel mount comes with a 2-1/2" shank to fit any 2-1/2" x 2-1/2" receiver hitch, including CURT Commercial Duty class 5 trailer hitches. The shank features rounded edges for easier insertion, and it has two hitch pin holes to adjust the length of the ball mount from 11" to 12". This provides extra clearance, as needed, for the rear bumper, a spare tire or other obstructions.

The channel mount is set with a series of vertical holes to mount the included dual-ball. The holes are spaced 1" apart, allowing the ball mount to perfectly suit the trailer for smooth, stable towing. This channel mount offers a maximum drop of 6", and it can also flipped for a maximum rise of 5-1/4".

For safety you can be confident in, each CURT adjustable channel mount design undergoes strict testing procedures. This model is constructed from high-strength forged steel and rated for a maximum gross trailer weight capacity of 10,000 lbs. for the 2" ball and 20,000 lbs. for the 2-5/16" ball. This makes it an excellent choice for livestock haulers, large flatbed trailers, deluxe travel trailers and much more (never exceed the weight ratings of the lowest-rated towing component).

CURT adjustable channel ball mounts are not only built for tough jobs, but they are also engineered to offer smooth, quiet towing. Built into the adjustable shank is an anti-rattle mechanism -- a rubber bumper that goes between the shank channel and the trailer ball attachment. This anti-rattle bumper greatly reduces vibrations and noise coming from the coupling point, providing a smoother, quieter ride for the road ahead.

In the world of heavy-duty towing, harsh conditions and relentless exposure to the elements aren't uncommon. For this reason, the adjustable channel mount is finished with a highly durable carbide black powder coat finish. This helps withstand rain, snow, dirt and road salt, protecting the shank from rust and corrosion. The dual-ball is given a yellow zinc finish for additional rust resistance.

    Great product but

    Love this set up. I tried an aluminum adjustable from another company and hated it right away. This is rugged and functional. I’m only concern is when I’m driving with out a trailer the cotter pins come out. I’ve almost lost the main pin a couple times. It could be just my truck and the harmonics that it gives off when driving. (Yes I know you should remove this when not towing but this has happened in a span as short as 5 miles)
    Other then that love this product and now I remove the ball when driving with out trailer.

    It would be nice to have a more positive lock in place other than the cotterpins.

    Don’t let this stop you from buying, I would buy it again no problem.

    good hitch

    I like this hitch a lot. It is easy to swap ball sizes. The one down fall to this hitch is that curt does not offer a piece for mounting your own ball or hooking a pined farm trailer to. I would buy one in a heartbeat if one was offered.

    Updated design

    They updated the anti rattle from a screw type to a large rubber dampener. Works much better. Also the hitch fits a little more tightly so it does not rattle as much. Good to know Curt is listening to their customers. Would definitely recommend

    Just received my hitch thru Amazon and the unit seems to be very well built, but like Jeff S says, and other reviews on Amazon, the anti-rattle bolt is a bit to short to do any good. It would not cost Curt to make this bolt a 1/4" longer so that it actually seats well into the ball mount. I will now have to go to the local hardware store and buy a longer bolt.

    Heavy Hitch

    Love the hitch, Heavy and duriable.

    One issue I have been having anti rattle bolt will work itself loose while towing, when not in direct center positon of ballmounts. Thinking I need another bolt to hold the pins tight.
