Three factors to consider

There are three main things to consider when selecting a trailer hitch ball mount: how much weight you are going to be towing, what size receiver tube your trailer hitch has and how much drop or rise your ball mount will need (below).

Trailer weight vs capacity

First, be sure to select a ball mount with enough gross trailer weight capacity to fit your trailer. Trailer weight is one of the most important aspects of towing, and you should never exceed the weight capacity of any component of your vehicle, trailer or trailer hitch setup.

Hitch receiver size

Next, determine what size shank you will need. Receiver tubes come in a handful of standard sizes, including 1-1/4, 2, 2-1/2 and sometimes 3 inches, so finding a ball mount to match is relatively easy.

How to determine drop or rise

After you know how much weight you will be towing and the size of your receiver tube, you will need to determine the drop or rise necessary for your trailer.

Drop or rise is the amount of height difference between the trailer and your tow vehicle, whether that difference is positive (rise) or negative (drop).

The diagram offers a quick explanation for how to determine your needed drop or rise. Take the distance from the ground to the top of the inside of your receiver tube opening (A), and subtract it from the distance from the ground to the bottom of the trailer coupler (B).

B minus A equals C, the drop or rise.

CURT class 3, or standard-duty, ball mounts are a step up from classes 1 and 2. They feature a 2" x 2" shank and have a higher weight capacity for towing heavy-duty trailers, including utility trailers, boat trailers, campers, single-horse livestock trailers and most recreational vehicle trailers. With class 3 trailer hitches being the most common type of trailer hitch for pickup trucks and SUVs, the class 3 ball mount, by association, is an excellent complement to this trailer hitch and these larger vehicles (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc).This particular class 3 ball mount can be used in the drop position to provide a drop of 8", a gross trailer weight capacity of 5,000 lbs. and a tongue weight capacity of 500 lbs. It can also be flipped to provide a rise of 6", a gross trailer weight capacity of 3,500 lbs. and a tongue weight capacity of 350 lbs. It features a length of 13". Class 3 ball mounts are CNC-formed and robotically welded to ensure unwavering precision and dependable strength in each and every unit. We mechanically descale each one to provide a smooth surface for a long-lasting finish. This class 3 ball mount comes with a durable gloss black powder coat finish to protect against corrosion, scratches, UV damage and more to give it the thick skin it needs to face the road ahead.

Puts my trailer on the level
Reviewed in the United States ?? on November 9, 2017

I purchased the Curt hitch with an 8" drop, which I needed to hook up my utility trailer to my F150 4x4, which seems to be about six feet off the ground. This hitch allows the trailer to ride almost perfectly level. The slanted design also positions the
trailer jack behind the lowered tailgate, keeping it from rubbing on the jack. A much more affordable option than the adjustable hitches. A well made hitch.

Perfect drop and stand-off!

Perfect hitch for towing my teardrop with my Suburban. Just the right amount of drop and the added stand off gives me the clearance to open the rear hatch of the Suburban while still hitched to trailer.
