The Shocker Gooseneck Air Hitch with Shift Lock Coupler adds instant air ride to your gooseneck trailer in minutes, delivering smoother, safer towing every mile. It's a patented air suspension system that completely replaces your gooseneck trailer's factory stem and coupler, using a built-in air spring bag and dual bump cushions to filter and absorb the chucking, bangs, bumps, jerks, and tugs you normally feel when towing a gooseneck with a hard connection. The result is a much smoother, more controlled ride for you, your passengers, your animals, and your cargo, plus reduced wear, tear, and breakage on both your truck and trailer. This version is built for trailers with a 4" or 100mm square inner tube stem and straight pin holes, paired with Shocker's patented, exclusive 30,000 lb Shift Lock coupler for a 2-5/16" gooseneck ball.

It's the preferred gooseneck hitch for hotshot haulers, farmers, contractors, and horse trainers, and it works great on gooseneck end dumps, flatbeds, race haulers, livestock and stock trailers, toy haulers, tilt trailers, and horse trailers. Whether you tow occasionally or you're running hotshot loads all week, this system adds air ride cushioning that your truck, your trailer, and your animals will appreciate. The Shift Lock coupler is the only gooseneck coupler that captures the ball on both sides, so you can see at a glance whether it's locked. It installs in minutes, is tunable for any load, and even helps save fuel. Made in the USA by Shocker Hitch in Jamestown, ND.

The heart of the system is Shocker's rocker arm pivot design, engineered specifically for the way a gooseneck trailer moves. It produces a front-and-back motion, and that fore-aft jerk is the biggest and most fatiguing motion you feel when towing a gooseneck. By filtering, dampening, and absorbing that motion through the built-in air ride system, dual external bump cushions, and an internal bump inside the air spring bag, the Shocker delivers heavy-duty yet very smooth performance and eliminates the jerks, bucking, bangs, and chucking of a hard connection. It's the only air ride hitch that works exclusively in that forward-and-back motion, and it's tested, trusted, and proven to work better than other cushion hitches, without the parallel linkages, shock absorbers, torsion arms, and other over-engineered gadgets those hitches rely on.

The benefits are real and wide-ranging. Because the air ride absorbs the damaging forces of a hard connection, it reduces stress, wear, tear, and breakage on your truck's driveline and frame, your trailer's welds, and your cargo, while making the ride dramatically less stressful for you, your passengers, and your animals. That matters to horse, livestock, and hotshot haulers alike: your animals and your freight get a smoother, calmer ride. The smoother connection also gives you improved control and comfort, filtering the natural tugs between trailer and pickup to make towing safer, and customers report saving one mile or more per gallon on fuel.

The Shift Lock coupler and square stem make it both secure and a precise fit. The patented, exclusive 30,000 lb Shift Lock coupler is the only gooseneck coupler that captures the ball on both sides, with an easy-to-use handle for hooking up and disconnecting and a clear, at-a-glance indication that it's locked on the ball. This standard version extends the coupler 3 inches forward of the factory location and has 3 height adjustment holes (if you run a short-bed truck and need more cab clearance, Shocker's 9" offset version is the one to choose). The system mounts on a thick-wall, heavy-duty replacement stem that fits 4" or 100mm (3-15/16") square inner tube stems with straight pin holes, matched to your trailer's specific stem. On this standard version, the air ride sits behind the gooseneck hitch and out of the way, and it's fully tunable: just add air for heavier loads (patents #11,370,257 B1 and D898,628, with additional patents pending).

Clear-cut installation instructions are included, and downloadable setup guides, dimension diagrams, and an installation video are available.
