You've had close calls with your gooseneck trailer long enough. The 9" offset on this coupler gives you more clearance when you turn. It's perfect for short beds, full-width front trailers, or any setup that runs tight near the cab.


Highlights

  • Offset for Clearance: 9" forward extension helps prevent cab strikes on short beds and tight turns.
  • Secure Hookup: Shift Lock coupler grabs the ball on both sides and locks when it drops on.
  • Ideal for Rebuilds & Replacements: Great fix when your original stem is worn, bent, or outdated.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

Built-In Offset for Cab Clearance

Shocker Hitch Installed

If you've got a short bed truck or a gooseneck trailer that cuts in too tight, you know how close things can get in a turn. The 9" offset on this coupler moves the hitch point forward to give your trailer more breathing room up front, helping you clear the cab when backing up or cornering sharp.

Hook Up and Forget It

Shocker Hitch Latches

The Shift Lock coupler uses a dual-jaw design to grab both sides of the 2-5/16" ball, creating a firm, centered connection that holds steady under tension. Many latches only grab your ball from one side, which can leave room for slop. This one clamps evenly and helps cut the jolt when you take off or stop. The locking handle sits up top, so you can see when it's latched. 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.

Video Transcript for Review of Shocker Hitch Gooseneck Coupler - Coupler with Inner Tube Only - SHK23YR

Hi, everyone, Steve here with etrailer.com. Today we're looking at a shocker hitch, the Shocker hitch gooseneck stem. It has a nine inch extension, and it's a coupler at 2 5/16 inch for your gooseneck ball and a square tube. The whole system's rate at 30,000 pounds. So folks, you can completely replace your factory inner tube, the stem, and the coupler all in a matter of minutes. So this nine inch offset is gonna extend that coupler nine inches forward, and it's gonna be ideal for short bed trucks pulling gooseneck trailers.

Now it is a heavy duty application. As you can see, it's pretty thick here on all the metal. Everything's been nice welded. It's gonna give you the strongest possible rating of 30,000 pounds and 6,000 pounds of tongue weight on the tongue itself. Now these are built for heavy duty gooseneck hauling.

Everything here as far as the shift lock coupler itself by Shocker, is a patent take, game changing design. It's dual latching, so there's like a U-bolt here in the front, if you will, and that's gonna go around and latch both sides with a simple pool of the pin and everything. So let me pop this off here real quick. So again, whenever it's down like this and you can put the hole through, you can see right here. Now you know that it's locked in place.

And then you can put that pin in to just make sure that it's not moving after it's in that position. So very nice design, nice matte black powder coat finish. It's impact resistant. It's not gonna corrode or rust on you anytime soon. Now again, this tube here is a four inch or 100 millimeter square stem, and you have four holes of adjustments on the stem here.

So those are 2 3/4 inches apart. Center on center all the way up here. Again, four options there for adjustments so you can change the height as needed. So just a great design. One thing to note, obviously there is no outer gooseneck tube. That should already be on your trailer obviously. But if you do need one, reach out to us here, chat, text, email, we can set you up with the right size you need as well. Folks, I'm Steven. That's gonna wrap it up for our look together at this Shocker hitch shift lock gooseneck with a nine inch extension coupler. I'm Steven, thanks for watching.
