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" shank to fit any 2" x 2" receiver hitch. The shank 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 14,000 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 Adjustable Hitch!

    I purchased this hitch as I have two vehicles I use to tow with, a 2002 Ford F-350 4x4 and a 2019 VW Atlas AWD. The Curt 45900 provides the option of using a 2 inch or 2 5/16 inch ball and various height positions to assure proper leveling of the trailer. Be advised this is heavy duty, with emphasis on heavy. I also purchased a set of Curt
    locking hitch pins for security. High quality and versatile product.

    45900 Great Setup

    Got one not long ago and couldn't have been happier with it. Bought a new truck and now could really use a replacement shank with at least 3 inches more drop though!! Any plans on offering one SOON???

    Seems to be a great heavy duty hitch. Everything fit together and looks good with the ball installed. Looks hazardous to shins etc. without the balls in place. Maybe I will have someone fashion a step to replace the balls.

    I would also like to have a 1 7/8" ball and a pintle/ball. It seems that those would be useful additions to the 2" and 2 5/16" combination. Oh, and maybe a step!

    I would also like to get a lock pin for the combination ball. I could then leave it in without fear of theft.

    This product offers such a variety of options, towing is safer and more comfortable. Recommend anyone towing more than 6000 lbs on a bumper hitch use this device.

    Great Mount

    My F-250 has a 4 inch lift and I needed a better way to level out my trailer. I bought this hitch and it works great. Very well built and secure. Highly recommended
