Class 4 Ball Mounts
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 feature a strong steel 2” x 2” shank and come in two weight capacity options. Choose from models with up to 10,000 lbs. of gross trailer weight capacity and 1,000 lbs. of tongue weight or 12,000 lbs. of and 1,200 lbs. of TW.
CURT heavy-duty ball mounts are built to complement CURT class 4 trailer hitches. They are perfect for towing large boat trailers, RVs, livestock and horse trailers as well as a variety of other farm and industrial-type trailers. 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.
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.
