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.
A gooseneck trailer sitting in the yard is one of the easiest things you own to walk off with. Anyone who can back a truck under the coupler and drop it on a 2-5/16" ball can drive away with your trailer. This Demco gooseneck coupler lock shuts that door. It's a pad lock style locking kit built specifically for Shocker gooseneck hitches running the Demco EZ Latch coupler, so when you're parked and not towing, the coupler can't be latched onto a ball. Made of steel and sized for the 2-5/16" Demco gooseneck coupler, it stops a thief from hooking up and pulling off with your trailer. The pad lock is sold separately, so you can key it to match what you already carry. In stock and shipping from Canada, no border wait, for gooseneck hitches equipped with the Demco coupler.
When You Only Need the Coupler
Already own a Shocker tongue mount and the original coupler is worn or damaged? You don't have to buy a whole new tongue mount. A standalone Wallace or Demco coupler swaps in and replaces just the head, so you're back towing for a lot less.
