Improves Safety
By giving you improved control of your tow vehicle and trailer. The Gooseneck surge air hitch system allows for better control of your pickup and the trailer it is towing.
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.
You feel it every time a loaded gooseneck grabs the truck on a hard stop or a frost heave: that forward-back jerk that pounds the bed, the trailer stem, and everything riding in back. The Surge Air Gooseneck Standard 30K kills that jerk. It swaps your factory inner stem and coupler for a patented forward-back airbag system rated at 30,000 lbs GTW, so every tow rides on air. This multi-fit-square version pairs a Demco EZ Latch coupler for 2-5/16-inch balls with stem options that fit nearly any gooseneck trailer maker, and it drops in in minutes.

Installation
Watch the official install walkthrough for this hitch — the exact steps and tools, straight from the manufacturer.
How Surge Air Works for Goosenecks
The worst shock in gooseneck towing is the forward-back jerk between your truck bed and the trailer stem. Surge Air is built to soak up that exact motion.
Forward-Back Motion Airbag
An air spring sits behind the inner stem and eats the forward-back jerk you feel every time you get on the throttle, hit the brakes, or roll over broken pavement.
Rocker Arm Pivot Design
A simple rocker arm does the job of parallel linkages, shocks, and torsion arms. Fewer moving parts means less to maintain and a longer life under heavy use.
Adjustable for Any Load
Add air when the load is heavy, bleed it off when you are running empty. One valve takes the same hitch from a fully loaded equipment trailer to a deadhead run home.
Drops Into Your Existing Stem
The multi-fit-square drops straight into your factory inner stem. No drilling, no welding, no cutting into the truck bed. The air ride lives between the stem and the coupler.

Multiple Stem Options
Pick the version that matches the inner stem your trailer already uses. Same air-ride chassis, same Demco EZ Latch coupler, just a different inner stem shape.
Multi-Fit Round (4" or 100mm)
Patent-pending round stem that fits both 4" and 100mm trailers with straight or angled pin holes. The catch-all choice for round-stem trailers.
Multi-Fit Square (4" or 100mm)
Fits both 4" and 100mm square inner stems with straight pin holes. Covers most modern square-stem gooseneck trailers.
4-1/2" Square Stem
Heavy-wall stem for trailers that run the bigger 4-1/2" square inner stem. Common on PJ, Big Tex, Diamond C and other heavy-duty builds.
Top-Crank 100mm Square
Made to replace top-crank handle stems on trailers like Bison and other makers that use the crank-style adjustment.
Driving a Short-Bed Pickup?
This Standard 30K sits 3" forward of your factory coupler, which is fine on a long-bed truck. If you run a short-bed pickup and the trailer nose crowds your cab on tight turns, go with the Surge Air Gooseneck 9" Offset 30K instead. Same air ride, with the coupler set 9 inches farther forward to keep the trailer clear of the cab.
Built to Last
Thick-wall steel through and through, with a patented Demco EZ Latch coupler. The air spring is the same multi-ply rubber design used in commercial air suspension systems, and the rocker arm geometry gives you fewer wear points than a parallel-linkage hitch. Backed by Shocker Hitch's 60-day satisfaction guarantee. In stock and shipping from Canada.
