Works For

Coupler lock kit fits all 30K Shift Lock gooseneck coupler.

Stop destroying your trailer and cargo.

Every bump, pothole, and expansion joint sends a violent jolt through your trailer frame, damaging cargo and wearing out your truck. Shocker Air Ride Hitches absorb that punishment at the coupling, before it reaches your trailer.

Leave a gooseneck trailer parked in a yard or a lot and it's about the easiest thing on the property to steal. Anyone with a truck and the right ball can back up, drop onto your coupler, and pull away in under a minute. The Shocker Shift Lock Gooseneck Coupler Box Lock Kit shuts that down. It's custom-made to lock securely onto your Shocker 30K Shift Lock gooseneck coupler so nobody else can hitch up and drive off with your trailer. Built from 1/4-inch, 7-gauge heavy-duty steel and finished in black powder coat, it stands up to the weather, holds its clean look for years, and helps protect whatever you're hauling, whether that's a car, a horse, or any other trailer riding on your Shift Lock Goose.

  • Three-piece kit (base, slide attachment, disc lock with two keys) that goes on in minutes.
  • Locks your gooseneck coupler shut so your trailer can't be hitched and stolen.
  • Add the Gooseneck Stem Set Bolt Lock Kit to lock the inner tube and coupler too (sold separately).

  • Works only with Shocker gooseneck hitches that use the Shift Lock coupler (silver handle).

Installation

Watch the official install walkthrough for this hitch — the exact steps and tools, straight from the manufacturer.

Does It Fit Your Hitch?

  • Made for the Shift Lock coupler: it fits the Shocker gooseneck head with the silver handle, no guessing.
  • Fits every 30K Shift Lock gooseneck coupler, so if you're running the 30K Goose this is your lock.
  • Works only with Shocker gooseneck hitches that have the Shift Lock coupler (the one with the silver handle).

How It Locks Up

  • Goes on in minutes: three pieces (base, slide attachment, and a disc lock with two keys) and you're locked up.
  • Locks the coupler shut so nobody can hitch to your trailer and tow it away.
  • Want it fully covered? Add the Gooseneck Stem Set Bolt Lock Kit to lock down the inner tube and coupler too (sold separately).
  • Won't fit Bulldog, Wallace Forge, or Ease Guide couplers. This is a Shocker Shift Lock part only.

What Shift Lock Does

New to the Shift Lock coupler? It grabs the gooseneck ball on both sides, so you get a click you can hear and an indicator you can see when it's locked on right. Shift Lock parts like this let you upgrade an older gooseneck or swap out a worn Shift Lock head without buying a whole new hitch.
