When you’re towing heavy equipment, livestock, or a big fifth wheel conversion, you need a hitch that doesn’t back down. The Curt Custom Underbed OEM-Style Gooseneck Trailer Hitch is rated at 32,500 lbs gross towing weight and 8,125 lbs vertical load. The 2-5/16" pop-in ball locks in with a built-in ball-bearing system for a tight, dependable connection that keeps things stable mile after mile. It’s been tested to meet SAE J2638 standards for heavy-duty towing performance, so it’s ready to haul whatever your trailer demands.
This setup makes installation straightforward even if you’re doing it solo. The compact, easy-to-handle pieces are light enough to lift and hold in place without help. It bolts directly to the frame with no welding or frame drilling required—only the bed holes for the ball and safety chains. Fewer parts and steps mean less hassle getting it installed, and once it’s in, the 5/8" thick spring-loaded chain loops are built in and ready to work.
When you’re done towing, just lift and turn the integrated lever to unlock and remove the ball for full bed access. The underbed design keeps things clean—only the ball hole remains visible when the ball and chain loops are out. You get an unobstructed bed for loading hay, tools, or any gear that won’t fit around a permanent hitch. And when it’s time to tow again, the pop-in ball drops right back into place and locks in instantly.
The sturdy steel frame gives this hitch the strength to handle heavy loads while holding up to rough use over time. Its liquid A-coat finish adds a durable layer of rust protection that keeps it looking solid even after years of towing in wet or salty conditions. It’s backed by a limited lifetime warranty for lasting confidence on every haul.

It works well towing an 18000lb trailer. I wish they included a feature to flip the hitch boll when its not in use, as no matter where I position it in my truck, I keep hearing it roll back and forth while driving, which is quite annoying.
