Replacement inner tube stem for
Shocker Gooseneck Surge® Air Hitch. Only fits the Shocker gooseneck surge air hitch.
Designed for 4.5" square gooseneck
air hitches with straight hole pins.
Fast Installation
Drop-in fit using standard hitch pins — no drilling, welding, or special tools required to install.
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.
The gooseneck stem is the working heart of your Shocker Gooseneck Surge® Air Hitch. It's the inner tube that moves and soaks up the jolt every time your trailer slams a frost heave or you have to stand on the brakes. Over the miles the bushings wear, or you trade up to a new gooseneck trailer and the pin setup no longer lines up. This replacement stem gets you back on the road without buying a whole new hitch. It's the inner tube stem for the Shocker Gooseneck Surge® Air Hitch, and only that hitch. It's built for 4.5" square gooseneck air hitches that run straight hole pins, and it bolts straight into the Shocker gooseneck air hitch frame assembly. It comes with 2 brass bushings and a grease zerk so the fresh unit rides smooth and stays greasable from the first mile. Stocked in Canada and ships direct, no border wait. Note: If you pick up a new gooseneck trailer and need a different stem to match, order this and swap out your stem to fit the new trailer.

When to Order a Replacement Stem
Grab a replacement stem when the bushings are worn from years of hard miles, or when you're moving to a new gooseneck trailer and need the pins to line up again. The rest of your hitch keeps working, so you only replace the piece that's done. Always confirm fitment by SKU before you order.
