About This Product

The Reese UMS 21K is the more reasonably-sized version of their Universal Mounting System hitch. Twenty-one thousand pounds of towing handles the majority of fifth wheels on the market with room to spare. Same UMS flexibility that works across different truck brands and configurations.

For Ford trucks with factory pucks, installation is standard puck-mount procedure. Drop the legs in, secure them, attach the head. The UMS design means this same hitch can also work with other mounting setups if you ever change trucks or need to move it.

Construction quality is typical Reese - they have been building hitches and towing equipment for decades. The head pivots smoothly, the jaws grip tight, and the whole assembly is built to last. Powder coat finish resists rust and weathering.

Twenty-one thousand pounds is enough for most people. Unless you are towing something genuinely massive, this capacity covers everything from mid-size fifth wheels up through large luxury models. Going higher than you need just adds weight and cost without real benefit.

Good option if you want the UMS mounting flexibility or prefer the Reese brand. For Ford Super Duty trucks with factory puck prep. Check bed length requirements - long beds are straightforward, short beds may need a slider depending on your specific trailer.
