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 6", a gross trailer weight capacity of 7,500 lbs. and a tongue weight capacity of 750 lbs. It can also be flipped to provide a rise of 4", a gross trailer weight capacity of 6,000 lbs. and a tongue weight capacity of 600 lbs. It features a length of 9-1/4". Class 3 ball mounts are CNC
