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.

Air ride technology

Built in air ride system, cushions the ride & absorbing the road shock

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.

When you're hauling a loaded stock trailer or an equipment trailer sitting near your truck's max rating, every frost heave and hard stop slams straight up through the receiver into your truck, your trailer welds, and whatever's riding in back. A rigid ball mount has nothing to give, so the rig chucks and jars and every stop turns into a fight. The Shocker HD Air Hitch & Drop Ball Mount w/ 2-5/16" Ball & Sway Bar Tabs puts an air spring between the truck and the trailer to soak that shock up before it reaches you. It's the heavy-duty red 20K at the top of Shocker's bumper-pull lineup, sized for F-350, RAM 3500, and dual-rear-wheel one-ton trucks running a 3-inch receiver (class V/VI). It handles 20,000 lbs of trailer and up to 2,000 lbs of tongue weight on a beefier-wall version of Shocker's signature 8-hole chassis with an upgraded HD-rated airbag. If you own a one-ton truck and haul the heaviest legal bumper-pull loads, this is the hitch built for it.

Key Highlights

  • Hauls up to 20,000 lbs of trailer and 2,000 lbs of tongue weight, the heaviest bumper-pull rating Shocker builds
  • Reinforced multi-ply airbag rated for the full 20K, so it keeps cushioning the ride even at max weight
  • Thicker chassis walls than the Original 14K, the same footprint with more steel behind it
  • Built for a 3-inch receiver, the size dual-rear-wheel one-ton trucks run
  • Add or release air to dial in ride height and load support for whatever you're towing that day
  • Sets up as a 4-1/2" to 8-1/2" drop ball mount so you can level the trailer and spread the load evenly
  • Finished in Shocker's iconic safety-red, impact-resistant powder coat that stands up to gravel and weather
  • Backed by our 60-day satisfaction guarantee

Installation

How Shocker HD Air Ride Works

20K-Rated Air Spring

The air bag uses a heavier ply count than the 14K version, so it carries up to 20,000 lbs of trailer while still soaking up the bumps that would otherwise hammer your truck and your cargo.

Adjustable for Heavy Loads

A heavy trailer can swing 1,000+ lbs between empty and loaded. Air up for the max-weight run, bleed it back down on the deadhead home. The HD airbag has a wider usable pressure range than the 14K, so it covers both ends.

Reinforced 8-Hole Chassis

It keeps the same outer shape as the Original line, so every Shocker ball mount still fits, but the wall steel is thicker and the welds are reinforced to carry the 20K loads.

Rocker-Arm Pivot

Shocker's down-and-back motion runs on a single pivot, with no slides, rollers, or stacked airbags, even at HD loads. Fewer moving parts under heavy stress means less to wear out and a longer service life.

Who Buys the HD 20K

Built for one-ton trucks and the heaviest legal bumper-pull combinations.

  • F-350, RAM 3500, and Silverado 3500 owners towing near their max trailer rating
  • Livestock haulers pulling 30+ ft bumper-pull stock trailers
  • Equipment and skid-steer haulers running 16k+ tilt-deck trailers
  • Big enclosed cargo trailers and car haulers up to 20,000 lbs
  • Dual-rear-wheel trucks with a 3-inch receiver that need a matched HD hitch
  • Anyone whose Original 14K is bottoming out under heavy tongue weight

HD vs. Original: What's Different

Same chassis silhouette, same attachment ecosystem, with three meaningful upgrades:

Option 1

Heavier Airbag

A multi-ply rubber bag rated for the full 20K GTW with a wider usable pressure range, so it carries heavier tongue weight without bottoming out.

Option 2

Beefier Walls and Welds

Thicker steel and a reinforced weld pattern at the high-stress points, rated for 2,000 lbs of tongue weight where the Original 14K stops at 1,400 lbs.

Flippable Drop and Rise Geometry

This hitch ships set up as a 4-1/2" to 8-1/2" drop ball mount. Most Shocker ball mounts are reversible, so you can flip the mount to turn that drop into rise, or use the 8 adjustment holes to fine-tune coupler height. Heavy bumper-pull trailers are picky about sitting level. Run it too high or too low and you dump the weight onto the trailer's front or rear axle, so take the time to dial it in.

Built for Maximum Bumper-Pull Loads

Reinforced heavy-wall steel takes the abuse of maximum bumper-pull loads, and Shocker's signature impact-resistant safety-red powder coat keeps rust and chips off through years of gravel and weather. It's in stock and ships direct from Canada, so there's no border wait. If the HD air bag ever needs replacing, it swaps out in minutes using the same simple Schrader-style fitting as the 14K.
