The Shocker 20K HD Air Receiver Hitch adds instant heavy-duty air ride towing to your pickup and trailer, transforming a rough, jarring tow into a genuinely smooth one. It's a miniature air suspension unit that mounts between your truck and trailer, channeling road shock, tugs, jerks, bumps, bangs, and sway through a built-in heavy-duty air spring bag and dual urethane bump cushions. Instead of the harsh, rigid connection of a standard ball mount, the 20K HD cushions every mile, creating a smoother, safer, more comfortable ride for both the tow vehicle and the trailer. It's the heavy-duty member of the Shocker air-hitch family, with thicker plates and a heavy-duty air spring for the biggest bumper-pull loads.
It's ideal for heavy-duty truck owners towing large bumper-pull trailers, big equipment, car haulers, campers, RVs, and stock trailers who are tired of constant bumps, jerks, and vibrations. Beyond comfort, the air ride system naturally reduces trailer sway, protects your truck's driveline and frame, the trailer, and your cargo from the damaging forces of a hard connection, and saves you money on breakage and repairs. Best of all, it's tunable: add air for heavier loads or reduce it for lighter ones to dial in the perfect ride and load control. The 20K HD Air Hitch is offered in two receiver sizes and two finishes so you can match it to your truck and your style, and every version is made in the USA by Shocker Hitch in Jamestown, ND.
Key Features
- Heavy-duty built-in air ride suspension – A built-in HD air spring bag and dual urethane bump cushions absorb road shock, tugs, jerks, bumps, and sway for years of heavy-duty performance, creating a much smoother ride for both the tow vehicle and the trailer.
- 20,000 lb capacity with adjustable dual combo ball – A 20,000 lbs. GTW / 2,000 lbs. tongue weight frame rating, 3/8" thick HD side plates, and an adjustable 2" and 2-5/16" combo ball with 1/2" to 4-1/2" of drop across 8 adjustment holes.
- Tunable air pressure for any load – Add air for heavier trailers or reduce it for lighter loads to optimize ride comfort, load control, and sway reduction for your exact towing weight.
- Available in two receiver sizes and two finishes – Choose a 2" or 2-1/2" receiver, and a standard safety-red frame with chrome balls or the blacked-out Max Black finish with black balls, to fit your truck and your style.
Features & Benefits
The heart of every 20K HD Air Hitch is Shocker's rocker arm pivot design. Unlike other air hitches that rely on slides, parallel linkages, rollers, shock absorbers, or multiple airbags, the Shocker uses a shock-damping rocker arm pivot that produces a distinctive down-and-back motion. This motion filters road shock into the integrated air ride system and dual bump cushions, working through the HD air spring bag, urethane cushions, and a greaseable 1" diameter 1045 carbon steel pivot bolt, which allows the pivoting rocker motion to happen smoothly and reliably for years of heavy-duty performance.
The safety story is worth understanding, because it's the reason an air hitch matters on heavy loads. When you tow a trailer, road bumps and jerks displace the weight. When a bump causes weight to come off the front of your vehicle, it can put too much tongue weight on the hitch, and without an air hitch that can lead to poor steering and braking. When a bump displaces weight onto the rear trailer tires, that can cause the trailer to sway. The Shocker HD absorbs and cushions these forces, which is why an air ride hitch, combined with a level towing setup, is proven to be both safer and smoother. It's also easier and less stressful on you, your passengers, animals, tow vehicle, trailer, and cargo, while reducing the wear, tear, and breakage that a hard connection inflicts on your driveline, frame, and welds.
Every 20K HD is heavy-duty and adjustable. Construction includes 3/8" thick HD carbon steel side plates with 8 adjustment holes, a thick top plate, a heavy-duty air spring, and dual bump cushions, and the air bag sits under the receiver tube for a short, stable ~10-1/2" distance between the receiver pin and ball center. You can fine-tune the air pressure for your load (never exceeding 100 PSI). A leveling spacer block is used on the HD models: on the 2" version it comes already installed, and on the 2-1/2" version it's included in the box, if the paddle sits at more than a 10-degree angle when aired up, the spacer levels it. Every 20K HD also anchors a system of 20+ interchangeable ball mount options, so you can swap the combo ball for drop, raised, drawbar, clevis pin, sway bar tab, pintle, pintle-and-ball, and other attachments. None of the 20K HD hitches work with a weight-distribution system.

- Receiver size: The 2" receiver fits full-size and midsize pickups, vans, and select SUVs; the 2-1/2" receiver fits 3/4-ton and 1-ton pickups, flatbed trucks, and service body trucks.
- Ratings (all versions): 20,000 lbs. GTW / 2,000 lbs. tongue weight (frame); 10,000 lbs. GTW on the 2" ball; 20,000 lbs. GTW on the 2-5/16" ball.
Installation & Use
- Fitment: Slides into a standard 2" or 2-1/2" receiver hitch tube (per the version you choose), for bumper-pull trailers with a 2" or 2-5/16" coupler.
- Before installing: Compress the air spring first. Use the provided cotter pin clip to push in on the valve core to release air pressure, and simultaneously push down on the paddle or squeeze the plates together to exhaust the remaining air.
- Mounting the hitch: Slide the shank fully into the receiver tube, align the pin holes, insert the 5/8" hitch pin, and lock it with the cotter pin clip.
- Installing the ball mount: Choose an attachment that lets your trailer sit level, install it into the Shocker frame, and secure it with the provided hitch pins and cotter pin clips.
- Setting air pressure: Hook up and load your trailer, then inflate the air spring; as pressure increases the unit rotates and lifts the hitch point. Add air until the top of the frame touches the tailgate-side bump cushion (or, for heavy loads, compresses it by about 1/8"). The "sweet spot" is reached once the main frame lightly compresses the truck-side bump cushion.
- Spacer block: Used on the HD models (installed on the 2" version, in the box on the 2-1/2" version). If the paddle sits at more than a 10-degree angle when aired up, install the spacer to level it.
- Important cautions: NEVER exceed 100 PSI. Grease the hitch ball to reduce wear and improve shocker action. Connect your safety chains and electrical cord before towing.

Care & Maintenance
A little routine care keeps your Shocker HD performing smoothly for years:
- Grease the ball and pivot bolt: Grease the hitch ball to reduce wear and improve shocker action, and keep the greaseable 1" 1045 carbon steel pivot bolt lubricated so the rocker motion stays smooth.
- Check air pressure: Periodically verify the air pressure is set correctly for your load so the paddle sits level; add or release air as your load changes. Never exceed 100 PSI.
- Keep pins clean and secure: Keep the D-handle pins and clips clean and confirm they are fully seated before every tow, along with your safety chains and electrical cord.
- Keep it clean: Rinse off road salt, mud, and grime periodically, especially after winter or coastal driving, to protect the powder coat finish.
- Inspect before towing: Check the HD air spring bag, bump cushions, side plates, welds, spacer block, and finish for wear or damage; confirm the ball is greased and secure.
- Storage: Store the hitch and ball mount somewhere dry when not in use; keep the shank clean so it slides in and out easily.
