Fusion Ball Mount with 2" Ball; 2" Shank; 7,500 lbs.; 4" Drop
A ball mount is a metal tube or bar that inserts into the receiver hitch and provides a mounting plate to hold a trailer ball. Ball mounts are made in a variety of styles and capacities to accommodate different trailers and coupler heights. The right ball mount should have a shank size that matches the receiver tube opening of your hitch, a weight rating that meets or exceeds your gross trailer weight and a rise or drop to help level your trailer.

Features & Benefits

  • Fits trailer hitches with a 2" x 2" receiver tube opening
  • Welded trailer ball accepts a 2" coupler
  • Permanently attached trailer ball cannot be loosened or stolen
  • 4" drop for precise trailer leveling
  • Hollow shank weighs less and can be used with an anti-rattle kit
  • Protected by a durable powder coat finish
  • Trailer ball features a polished chrome-plated finish

Determining Drop & Rise

To find the measurement of drop or rise for your tow vehicle and trailer, you will need to measure the receiver tube height (A) and the coupler height (B). B minus A equals C, the drop or rise needed. If C is a positive number, your ball mount will need to have rise. If C is negative, your ball mount will need drop.
