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.
Pull a loaded gooseneck over rough pavement and you feel it in your back, that hard forward-back jerk every time you brake, roll off a frost heave, or hit a bridge seam. It pounds your truck bed, your trailer stem, and whatever is riding in the back. The Surge Air Gooseneck Standard 30K swaps out your factory inner stem and coupler for a patented forward-back airbag system rated at 30,000 lbs GTW, so that jerk gets soaked up before it reaches you. This round-4-inch variant runs a Demco EZ Latch coupler for 2-5/16-inch balls and comes in multiple stem options to fit nearly any gooseneck trailer. It installs in minutes and puts air ride under every tow.

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.
Airbag Aimed Right at the Jerk
An air spring sits behind the inner stem and eats the forward-back jerk you feel when you accelerate, brake, or roll across broken pavement, so it never reaches the cab.
Simple Rocker Arm, Fewer Parts
A single rocker arm does the job of parallel linkages, shocks, and torsion arms. Fewer moving parts means less to maintain and a longer service life under heavy use.
Dial It In for the Load
Add air when you are loaded heavy, let some out when you are running empty. One turn of a valve takes the same hitch from a maxed-out equipment trailer to a deadhead run home.
Drops Into Your Existing Tube
The round-4-inch takes the place of your factory inner stem directly. No drilling, no welding, no cutting into your truck bed. The air ride lives between the stem and the coupler.
Trailers This Hitch Was Built For
Made for everyday 30K-class gooseneck work, whether you are a weekend horse hauler or a full-time hotshot trucker.
- 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
Match It to Your Trailer's Stem
Pick the variant that matches the inner stem already on your trailer. 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 fits both 4" and 100mm trailers with straight or angled pin holes. The catch-all pick if your trailer runs a round stem.
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 the larger 4-1/2" square inner tube you find on PJ, Big Tex, Diamond C, and other heavy-duty manufacturers.
Top-Crank 100mm Square
Built to replace the top-crank handle stem used on trailers like Bison and other manufacturers with crank-style height 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 in tight turns, go with the Surge Air Gooseneck 9" Offset 30K instead. Same air ride technology, with the coupler set 9 inches farther forward to keep the trailer clear of the cab.
Built to Last
Thick-wall steel where the loads live, plus 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 has fewer wear points than a parallel-linkage hitch, so there is less to go bad over the miles. Backed by Shocker Hitch's 60-day satisfaction guarantee. In stock and shipping from Canada.
