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 11-1/2". 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.
- Hollow shank weighs less and can be used with an anti-rattle kit
- CNC-formed, robotically welded and mechanically descaled for a perfect fit
- Protected by a durable powder coat finish
- Limited lifetime warranty (one-year finish, one-year parts)
- Trailer ball and hitch pin sold separately
