About This Product The GEN-Y Extended Dual-Ball Mount (SKU GH-034) is a 12 inch steel ball mount that fits 2 inch and 2.5 inch truck receivers, rated for 10,000, 16,000, or 21,000 pounds depending on the receiver size and ball size. It includes both a 2 inch and 2 5/16 inch ball on one mount. The 2 inch shank version measures 8.313 inches from the pin hole to the center of the ball and is rated for either 10,000 or 16,000 pounds, while the 2.5 inch shank version measures 8.75 inches from pin hole to ball center and is rated for 21,000 pounds. Both versions run 12 inches long overall and carry a 1,500 pound tongue weight rating. The extended length gives your trailer and tow vehicle more clearance than a standard-length ball mount, which matters most on tighter turns or with equipment mounted low on the truck. This mount is built for a straight truck receiver, not a drop hitch. The two included balls, 2 inch and 2 5/16 inch, cover most bumper pull trailers without needing a separate ball purchase, and you can add a 5/8 inch replacement hitch pin at checkout if you need a spare. GEN-Y fabricates this ball mount from steel, finishes it in a zinc rich epoxy primer and durable powder coat, and manufactures it in the USA. It weighs 20 pounds and carries GEN-Y's limited lifetime warranty. Every GEN-Y ball mount is tested to exceed SAE J684 weight testing requirements before it ships. Match the ball size to your trailer coupler before towing, and never exceed the rated towing capacity or tongue weight on any receiver, hitch, or coupling in your setup. *NOTE: These products are NOT intended to be used with a drop hitch. These are intended for use with truck receivers.
