CURT MANUFACTURING, LLC. part description

CURT class 1 ball mounts are designed for a variety of lightweight towing applications. For basic utility trailers, canoe haulers and other light-duty trailers, a class 1 ball mount gets the job done. CURT class 1 ball mounts are designed to complement our class 1 trailer hitches and come in several different styles, offering a range of shank lengths and drop and rise options. A class 1 ball mount is typically used on compact cars, full-size cars, minivans and crossover SUVs, but it can be used on virtually any trailer hitch with a 1 1/4" x 1 1/4" receiver tube (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc).This class 1 ball mount features a gross trailer weight capacity of 2,000 lbs. and a tongue weight capacity of 200 lbs. It has a length of 9 1/2" and a rise of 3". CURT ball mounts, like our trailer hitches, are built to last. They are made from quality steel that is CNC-formed and robotically welded to be an exact fit for your receiver hitch. To protect our class 1 ball mounts from corrosion, UV damage and scratches, we coat each one in a powder coat of high-gloss black for a sharp finish.


  • Fits trailer hitches with a 1 1/4" x 1 1/4" receiver tube opening
  • Equipped with a 3/4" hole to accept a trailer ball shank
  • 2 5/8" rise or 3 1/4" drop for precise trailer leveling
  • 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
  • Made in USA
