Sale price$75.00

When you demand more from your towing equipment, CURT heavy-duty ball mounts answer the call. For towing those especially heavy loads and bulky trailers, you need a ball mount that knows how to handle itself when the going gets tough. Our heavy-duty ball mounts are constructed from quality steel and feature a 2" x 2" shank. They are built to complement CURT class 4 trailer hitches and are perfect for towing large boat trailers, RVs, livestock and horse trailers as well as a variety of other farm and industrial-type trailers (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). With a few different drop height options and the ability to flip for optional rise, CURT heavy-duty ball mounts are built to work as hard as you do, from sunup to sundown.

This HD ball mount has a gross trailer weight capacity of 10,000 lbs. and tongue weight rating of 1,000 lbs. It measures 9-3/8" in length, has a 6" drop and can be flipped to provide 4-3/4" of rise. As with most of our ball mount line, CURT class 4 ball mounts are CNC-formed, robotically welded and mechanically descaled to create a flawless product. We finish our heavy-duty ball mounts in a gloss black powder coat to give them superior rust, chip and UV resistance. They also come with 1-1/4" ball hole to accept a trailer ball with a 1-1/4" shank.
