The BOSS 21K (Torsion-Flex) Drop Hitch (2 ½" or 3" Shank)

The BOSS 21K is rated to tow up to 21,000 pounds with a 2,400 pound tongue weight, and owners get the smoothest ride within a 1,500 to 2,400 pound tongue weight range. It comes with a 2.5 inch or 3 inch receiver shank, and the 3 inch option only fits select Ford trucks built after 2017. Tow capacity is always limited by the lowest rated component in your full setup, whether that's the hitch, the trailer coupling, or your vehicle's receiver, so check every link in the chain before loading to the full rating.

Yes, according to owner reports. GEN-Y's rubber torsion arms isolate the trailer connection from the tow vehicle, and owners report up to 90% smoother towing compared to a rigid, hard-connected hitch. Several verified reviewers describe noticeably less bounce over bumps and better fuel economy on long tows. The independent tracking between tow vehicle and trailer also improves sway control and braking, since weight stays distributed evenly across both vehicles instead of transferring straight through a solid connection point.

It's available with a 2.5 inch or 3 inch receiver shank. The 3 inch option is only offered on select Ford vehicles manufactured after 2017, so confirm your specific receiver size before ordering. Both shank sizes carry the same 21,000 pound towing capacity and 2,400 pound tongue weight rating. If you're not sure which shank your truck has, measure the receiver opening directly or check your owner's manual before choosing an option at checkout.

Use the 2 5/16 inch ball, not the 2 inch ball, when towing with a pintle ring trailer. The dual ball mount included with this hitch has both 2 inch and 2 5/16 inch balls, and the hitch is designed for lunette rings of 1.5 inches or smaller. Using the wrong ball size on a pintle ring application isn't rated by GEN-Y, so match the ball to your specific coupler before towing.

No. GEN-Y states plainly that this hitch is not rated for winching or side-load applications. It's engineered and tested for towing loads up to 21,000 pounds within its drop and raise positions, not for the lateral or pulling forces involved in winching or side loading. If you need a winch-rated setup, contact GEN-Y directly to confirm compatibility with your specific vehicle and towing needs before attempting any winching with this hitch.

The BOSS 21K adjusts through drop and raise positions ranging from 6 inches to 21 inches, depending on which configuration you select at checkout, with anywhere from 4 to 6 adjustable positions within each range. Choose the configuration that lets your trailer sit level once hitched. A good starting point is measuring the difference between your tow vehicle's receiver height and your trailer's coupler height, then picking the drop or raise closest to that number.

The rubber torsion components carry a 5 year warranty, and every other part of the hitch is covered by GEN-Y's limited lifetime warranty. You can also add GEN-Y's TORSION-FLEX Lifetime Warranty at checkout, which extends coverage on the rubber components and connecting hardware for as long as you own the hitch. GEN-Y recommends a 500 mile break-in period once the hitch is installed, and publishes full warranty terms and the claims process on its site.

Yes. GEN-Y manufactures the BOSS 21K in the United States, fabricating it from heavy-duty steel and engineering it with SOLIDWORKS software before finishing it in a zinc rich primer and durable powder coat. The hitch weighs 100 pounds and is protected under multiple US utility and design patents, including US10639950B2 and US9505281B1. GEN-Y publishes USA Made compliance documentation on its site for buyers who want to confirm domestic manufacturing before ordering.
