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.
Hitch up a loaded gooseneck and you feel it in your spine: that hard forward-back jerk every time you roll off the throttle, catch a frost heave, or brake for a light. All that chucking beats on your truck bed, your trailer stem, and whatever you are hauling. The Surge Air Gooseneck Standard 30K takes it out of the equation. It swaps your factory inner stem and coupler for a patented forward-back airbag system rated at 30,000 lbs GTW, so the shock lands in the air spring instead of your rig. This square-4-5-inch build pairs a Demco EZ Latch coupler for 2-5/16-inch balls with several stem options that fit nearly any gooseneck trailer maker. It installs in minutes and puts real air ride under every tow, loaded or empty.

Installation
Watch the official install walkthrough for this hitch — the exact steps and tools, straight from the manufacturer.
How the Surge Air Works on a Gooseneck
The worst shock in gooseneck towing is that forward-back jerk between your truck bed and the trailer stem. Surge Air is built to soak up that exact motion.
Airbag That Kills the Forward-Back Jerk
An air spring sits right behind the inner stem and swallows the main forward-back jerk you feel when you get on the throttle, brake hard, or roll over a rough pavement seam. That is the shock that wears on a gooseneck, and now it lands in the air.
Simple Rocker Arm, Fewer Wear Points
A single rocker arm does the job that parallel linkages, shocks, and torsion arms handle on other hitches. Fewer moving parts means less to maintain and more life out of it under heavy, everyday use.
Tunes to Whatever You're Hauling
Add air when the load rides heavy, bleed it off when you run empty. The same hitch goes from a maxed-out equipment trailer to a deadhead run home with a turn of the valve.
Drops Into Your Existing Stem
The square-4-5-inch takes the place of your factory inner stem straight up. No drilling, no welding, no cutting into your truck bed. The air ride simply lives between the stem and the coupler.

Pick the Stem That Fits Your Trailer
Order the version 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)
This patent-pending round stem fits both 4" and 100mm trailers, with straight or angled pin holes. It is the most universal 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. It covers most modern square-stem gooseneck trailers.
4-1/2" Square Stem
A heavy-wall stem for trailers built around the larger 4-1/2" square inner stem. You will see this size on PJ, Big Tex, Diamond C, and other heavy-duty makers.
Top-Crank 100mm Square
Built to replace the top-crank handle stems found on trailers like Bison and other makers that use the 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. But if you tow with a short-bed pickup and the trailer nose swings close to your cab on tight turns, go with the Surge Air Gooseneck 9" Offset 30K instead. It uses the same air ride, with the coupler set 9 inches farther forward to keep the trailer clear of your 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 that runs in commercial air suspension, and the rocker arm geometry gives it fewer wear points than parallel-linkage hitches. It is backed by Shocker Hitch's 60-day satisfaction guarantee, in stock and shipping from Canada.
