Your old gooseneck coupler made every hookup a chore. You'd slam it down, jiggle the handle, and still wonder if it was locked. This one drops on and clicks into place so you don't have to keep walking back to check it over and over.


Highlights

  • Direct Fit: Square coupler drops into your gooseneck sleeve - built for long-bed clearance.
  • Secure Hookup: Demco eZ-Latch drops onto the ball and locks automatically.
  • Ideal for Rebuilds & Replacements: Great fix when your original stem is worn, bent, or outdated.
  • Bolt-On Installation: Replaces your existing inner tube - slide out the old, pop in the new.
  • Adjustable Fit: Four mounting holes spaced 2-3/4" apart let you dial in your ride height.
  • Made of Steel: Thick-wall tubing with welded components hold up under heavy loads and rough roads.

Features to know about

Hook Up and Forget It

Shocker Hitch LatchesShocker Hitch Latches

With some couplers, you're never quite sure if they're secure. This Demco eZ-Latch coupler fixes that. Just drop it onto the ball and it latches itself. There are no extra steps involved. Once it's connected, you know it's going to stay put. And if you're leaving your trailer hooked up somewhere, the InfiniteRule lock (IR66FR - sold separately) keeps the latch from being opened so no one can pull up and take it.
