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.
Every gooseneck tow starts and stops with a hard forward-back jerk between your truck bed and the trailer stem. You feel it in the seat, your cargo feels it in the deck, and your truck and trailer wear from it on every frost heave and hard stop. The Surge Air Gooseneck Standard 30K puts a patented air spring right in that path, replacing your factory inner stem and coupler so the full 30,000-lb GTW load rides on air instead of steel banging on steel. This multi-fit-square version drops into most modern square-stem trailers and comes with a Demco EZ Latch coupler for 2-5/16-inch balls, so you get air ride the first time you hook up.

Installation
Watch the official install walkthrough for this hitch — the exact steps and tools, straight from the manufacturer.
How Surge Air Smooths a Gooseneck
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.
Air Spring Right in the Jerk's Path
An air spring sits behind the inner stem, exactly where the forward-back jerk lives. It takes the hit every time you accelerate, brake, or roll across rough pavement, instead of passing it straight to your bed and your load.
Simple Rocker Arm, Fewer Parts to Fail
A single rocker arm does the work that parallel linkages, shocks, and torsion arms do on other hitches. Fewer moving parts means less to maintain and more years of hard use.
Tune It to the Load
Add air when the trailer rides heavy, bleed some out when it's empty. The same hitch handles a maxed equipment trailer and a deadhead run home with a turn of the valve.
Drops Into Your Existing Tube
The multi-fit-square replaces your factory inner stem straight across. No drilling, no welding, and nothing done to your truck bed. The air ride lives between the stem and the coupler.
Built for These Gooseneck Trailers
Made for general-purpose 30K-class gooseneck work, from weekend horse haulers to full-time hotshot truckers.
- Flatbed gooseneck trailers up to 30,000 lbs
- Horse and livestock goosenecks
- Toy haulers and enclosed race trailers
- End dump and equipment goosenecks
- Tilt-deck gooseneck trailers
- Hotshot trucking rigs and mixed-load haulers
Multiple Stem Options
Pick the stem that matches your trailer's current inner tube. Same air-ride body, same Demco EZ Latch coupler, just a different 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 most universal pick 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 running the larger 4-1/2" square inner stem. Common on PJ, Big Tex, Diamond C and other heavy-duty builds.
Top-Crank 100mm Square
Replaces top-crank handle stems on trailers like Bison and other brands that use the crank-style adjuster.
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 construction and a patented Demco EZ Latch coupler. The air spring is the same multi-ply rubber build used in commercial air suspension, and the rocker arm has fewer wear points than a parallel-linkage hitch, so there's less to break down the road. Backed by Shocker Hitch's 60-day satisfaction guarantee, in stock and shipping from Canada.
