“I've ridden in the trailer myself — the difference in shock is huge. Our horses come off so much more relaxed, and there's less wear on the truck and trailer too.”

Fast Installation

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.

On a gooseneck, the whole load rides on the neck, and a loose or out-of-spec sleeve on the front of the trailer is where slop, rattle, and hard shots through the frame start every time you hit a frost heave or grab the brakes. This weld-on outer tube sleeve is the socket that fixes that. It welds onto the front of a gooseneck trailer and gives your coupler stem a precision home to ride in, rated up to 40,000 lbs of gooseneck towing capacity. It is the same heavy-duty neck gooseneck trailer manufacturers often use, formed from 1/4" steel with precision tolerance to fit existing inner tube square gooseneck couplers. It comes in raw steel and is available three ways: 4" with a pinhole, 4.5" with a pin hole, or 4" for a top crank. Inner tube solid and air ride gooseneck stems and couplers ride inside it and are sold separately.

Key Highlights

  • Welds onto the front of your gooseneck to become the socket your coupler rides in
  • The same heavy-duty neck gooseneck trailer builders commonly spec from the factory
  • Three fits so you match your coupler exactly: 4.5" OD sleeve for a 4" square gooseneck coupler with straight pinhole, 4.5" OD sleeve for a 4" square gooseneck coupler with Top Crank, or 5" OD sleeve for a 4.5" square gooseneck coupler with straight pin hole
  • Formed from 1/4" steel so it takes shock loads without flexing
  • Precision tolerance to slide tight over existing inner tube square gooseneck couplers, no slop
  • 20" of sleeve height for plenty of weld surface and a firm grip on the stem
  • Ships in raw steel, ready to weld and finish to match your trailer
  • Four 3/4" set bolts with jam nuts lock the stem down and keep it from working loose

Cut to Fit, Right Down to the Hardware

Set bolts and pins take a beating and go missing over the years, and a loose fit is where slop and rattle begin. This sleeve and its four 3/4" set bolts are built to OEM spec, so the coupler stem seats tight and your Shocker gooseneck sets up the way it was engineered to instead of sloppy.
