Complementing the heavy-duty size and capacity of 3" x 3" trailer hitches, the CURT Industrial Duty ball mount is a dependable extension of your truck. Its 3" x 3" shank is built with an I-beam shape, giving it greater strength for maximum towing capacity. It is constructed from solid, forged steel, making it even stronger for the toughest of towing jobs.
To make sure this heavy-duty ball mount can keep up with the hardest-working trucks, we fully test it at our Detroit engineering facility. This allows us to rate this heavy-duty ball mount to 21,000 lbs. GTW and 2,800 lbs. TW.
CURT Industrial Duty ball mounts are also built to outlast the elements, featuring a highly durable carbide black powder coat finish, protecting the ball mount against rust, scratches and chipping. This particular ball mount also comes with a 1-1/4" trailer ball hole and a 2" rise and 4" drop to accommodate larger pickup trucks, helping the trailer to ride level with the road.

I have two of these ball mounts. The first one I got back in 2018 (pre-Covid). That is a great unit; solid/snug fit and MUCH better finishing overall. The one I recently received appears to have had little to no grinding, sanding, or finishing to smooth out the casting. It also fits in the receiver with substantially more slop up and down. Side to side fit is good but the up and down fit is pretty bad. Just looking at them side by side you'd think they were made by entirely different companies. . .

This would have been the perfect ball mount if it wasn't made in China. Ordered a Curt expecting an American made product.
