Upgrade your gooseneck trailer with the easy to use, patented dual latching Shift Lock coupler for gooseneck trailers.

The shift lock design makes it easy to see if you are locked onto the ball at a glance. This is rated at 30,000 lbs. and is the only gooseneck coupler that captures the ball on both sides. The Shift Lock handle makes it super easy to hook up and disconnect the gooseneck coupler from the ball. The 30K Shift Lock Coupler fits 2-5/16" hitch balls.

Our Shift Lock Coupler is easy, fast, and safe. We use dual latching simple sliding rods made with alloy steel to lock the ball in place.

Works great on gooseneck style trailers; dumps, flatbed, horse, race trailers, and more.
