Simple Pivot Design
uses a rocker arm pivot design which produces a down and back motion, much different than other air ride products on the market.
No Ball Coupler or Pintle
Ring Included. This does not include the ball coupler. We recommend a bolt on vertical channel wallace forge or demco ball coupler or a shocker pintle ring that is designed to fit the 3" wide front…
25,000 lbs GTW & 3,500 lbs Tongue Weight Capacity. (Note
For 25K tow capacity, make sure the coupler you use is rated at 25k).
Heavier Loads, Just Add Air
Fine tune for your towing weight. Just add air for heavier loads.
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 heavy trailer over frost heaves and hard stops and you feel every jolt slam through the hitch, into your cargo, and back into the truck. The Shocker Heavy Duty 25K Air Tongue Mount takes that hit for you. It bolts straight to your trailer A-frame and puts the air ride on the trailer instead of the truck, so any tow vehicle that hooks up gets the smoother pull. Rated up to 25,000 lbs GTW with tongue weight. Buy it as a base frame or with a coupler already installed. The built-in 3-inch front channel accepts a vertical-channel coupler or pintle ring.

How It Works
The Air Bag Takes the Hit
A 20K-rated air bag sits between the coupler and the trailer A-frame. It soaks up the jolt off a rough road before it can reach your trailer frame, your cargo, or your truck.
Tune It to the Load
Add or bleed off air to match the ride to what you are hauling. Heavy load, more air. Light or empty, less air. You set the pressure that rides right every trip.
Simple Rocker Arm Pivot
The coupler pivots down and back on a rocker arm, with no slides, rollers, or parallel linkages. Fewer moving parts means less to maintain and a longer working life.
Keeps Your Ground Clearance
The air ride sits above the trailer tongue, so you keep full ground clearance for steep approaches, off-road equipment trailers, and tilt-deck haulers.
Ideal For These Heavy Trailers
The 25K rating makes this the heaviest tongue-mount tier we offer, built for serious commercial and recreational haulers:
- End dump trailers and heavy equipment haulers
- Race car haulers and enclosed stacker trailers
- Skid steer and tilt-deck equipment trailers
- HD flatbeds and lowboys, within rating
- Large enclosed cargo and tool trailers
- Any A-frame trailer up to 25,000 lbs GTW with tongue weight
Two Mounting Geometries
Pick the version that matches how your trailer A-frame is built:
Vertical Channel Mount (SH-HD4000 series)
Fits a 3-1/2-inch wide vertical channel with a 2-inch center-on-center bolt pattern. Pin or bolt it in with 5/8-inch hardware (4-1/2 inches long is what we recommend). This is the most common setup on fabricated trailer A-frames.
Square Plate Mount, 4-Bolt (SH-HD4500 series)
Uses a 4-1/2-inch square bolt pattern and bolts straight to a flat plate on the trailer tongue. Four bolts and you are done. You will find this on a lot of factory-built dump and equipment trailers.
Bring Your Own Coupler, or Buy It Bundled
You can run the HD 25K as a bare frame or get it with a coupler already installed. The 3-inch front channel takes any vertical-channel-mount ball coupler or pintle ring rated up to 25,000 lbs. If you want us to pair one, good options are the Demco EZ-Latch (DEM-14040-81) at 21K, a Wallace Forge auto-locking coupler at 20K or 25K, or the Shocker SH-P20000-B pintle ring at 20K. One thing to remember. Your total tow rating can only be as high as the lowest-rated part in the chain, so match your coupler to your trailer GTW.
Why Mount the Air Ride on the Trailer?
Put the air ride on the trailer instead of the truck and every tow vehicle that hooks up gets the smoother pull, with no extra gear on each truck. That pays off most on fleet trailers pulled by different drivers, rental trailers, equipment trailers shared between operators, and any commercial setup where the trailer is the one thing that stays the same. The HD 25K is the heaviest tongue mount we make, built for end-dump operators, race haulers, equipment fleets, and anyone whose trailer matters more than which truck is on the ball that day.
