About This Product

The Demco UMS 31K is built for maximum weight. Thirty-one thousand pounds of towing capacity puts this at the top of the fifth wheel hitch market. If your trailer is genuinely massive - large toy haulers, commercial applications - this handles it without breaking a sweat.

UMS means Universal Mounting System - works with multiple truck brands and mounting configurations. For trucks with factory pucks, it drops in like other puck hitches. The flexibility is useful if you change trucks or need to move the hitch around.

At 31K capacity, everything is beefed up. Heavier construction, larger components, designed for continuous heavy use. The tradeoff is more weight and higher cost, but if you need the capacity, you need it.

Demco makes this straightforward - secure jaw grip, height adjustment, solid construction. No unnecessary complexity to maintain.

Make sure you actually need 31K before buying this. Most fifth wheels are well under 20K. But for heavy applications where capacity matters, this delivers.
