WARNING: Cancer and Reproductive Harm -

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-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.

    It fits 2011 Toyota Sienna

    What is not obvious from the photo is that behind the angled portion of this Ball Mount is a metal flange that sticks out towards the vehicle hitch. When I saw this I thought there was no way this Ball Mount would fit on my 2011 Toyota Sienna (in the rise position) because ithe flange would interfere with the bumper. However - it DOES FIT on the 2011 Toyota Sienna without touching the bumper! There is only about 1/2" of clearance, but it does fit.
