Shocker HD Air Hitch Ball Mount Installation Instructions

The Shocker HD Air Hitch ball mount is easy to install.  It comes complete with easy-to-understand instructions along with everything you need.  You can download the installation instructions or view the video below.

Shocker Air Installation: First you must compress the air bag. Do this by depressing the air valve and pushing down on air bag.
Once the bag has been compressed, you can install the unit into the receiver tube. Next install hitch pin.

Shocker HD Air Hitch Install Video

To Set Air: Hook up trailer using properly selected ball adaptor and height adjustment in order to a level trailer when loaded. Next, inflate the air bag. As air pressure increases, the unit will rotate lifting the hitch point. Install enough air to slightly compress top bushing or until bump stop clearance is approximately 1/8″.

Additional Set Up Notes:

  • When towing heavy trailers or trailers with high wind resistance it may be necessary to increase air pressure in the Shocker.
  • It is highly recommended that the hitch ball be greased to reduce wear and improve shocker action.

Maximum Air Pressure: Do not exceed 100 psi in the air bag, as it may damage the air bag.

Answers to Frequently Asked Questions

How much drop do I need?

How much air do I put in the Shocker Air Bumper Mount Receiver Hitch?
With your trailer hooked up to the tow vehicle, and loads positioned for transport, air up shocker until main frame rotates and lightly compresses top bushing (about 1/8″ of squeeze or pinch in the bushing). See our quick How To Set PSI in Shocker Bumper Hitch Video.

Will the Shocker Air Bumper Hitch work with Equalizer or Weight-Distribution?  If you are just use sway bars that hook to a mini ball, then yes, if you order the combo sway control ball mount attachment. If you have a equalizer or weight distribution hitch then it will not. However, check out our Air Equalizer for weight distribution hitches.  Note: If your pickup suspension can handle the weight of your trailer and doesn’t “squat” when you hook up your trailer to pickup, then you really don’t need a weight distribution hitch. A load leveling weight distribution hitch, distributes the weight between the pickup and trailer and is generally used if your pickup can’t handle the static trailer tongue weight load.

How long will it hold air? This is a sealed system that will hold air for weeks or months. If you haul the same trailer with the same load weight, it should be good for quite some time.

How long will the airbag last? Our airbags are an industrial bag and will last for years and years. They are similar to truck airbags but have been beefed up internally for our towing applications.

I have a 3″ receiver hitch? will this work?  Yes, you would order the air hitch with 2-1/2″ shank and then get a reducer sleeve that goes down from 3″ to 2 1/2″.

How do I know the Shocker Air receiver hitch will fit my truck?
We have made sure that the receiver air shocker will fit into most Ford, Chevy, Dodge, Toyota and SUV’s. There are some clearance issues with the Chevy Envoy, Ford Explorer, some imports and service body vehicles where the body extends below the receiver tube. The use of “reducer” sleeves on trucks with a 2 1/2″ receiver tube is not recommended. The Shocker Air receiver hitch is available in a 2″, 2 1/2″ & 3″ shank. Please indicated which vehicle you intend to use the hitch with, make/model/year and we will attempt to get you a great fitting hitch.

Note: A Shocker with 2″ shank will not fit a 2-1/2″ receiver even with a sleeve. This is because trucks with
a 2-1/2″ hitch have a deeper frame & the hitch that fits 2-1/2″ receiver is slightly deeper. However a
Shocker with 2-1/2″ shank will fit a 3″ receiver with sleeve.

How far below my pickup does the receiver air shocker hang?
Five inches below bottom of receiver tube.

How often do I grease it?
The grease does not just lube the pivot; it also keeps water and dirt out. You cannot over grease it, once every few months should do it.

Does the receiver air hitch work like or with an equalizer hitch?

Does the receiver air hitch work with sway bars?
Yes, it works with the friction style sway control, however you want to order one of the ballmount attachments that has the sway tabs installed.

How does the Receiver hitch work?
The Receiver air shocker is like a teeter totter. One end is an air bag, a pivot in the middle, and a ball at the other end. This gives a “pillow” effect at the ball end.

Should I tighten up the top jam nut on the receiver shocker?
No. The air shocker needs at least one half inch of play to work properly.

How much does an Shocker Air bag receiver hitch weigh?
The Receiver Air Shocker weighs 40 pounds

Customer Reviews

  1. 2nd hitch I have purchased. extremely happy with the function and quality of both.

    – dann olson
  2. Have only made a few trips with the new hitch and one of my smaller trailers, but it’s obviously a game-changer. The trailer and truck are remarkably isolated from each other. Potholes, railroad tracks, tar strips, and more. The trailer bouncing is not transmitted into the truck anymore. The 8-1/2″ height adjustment is perfect to handle the wide range of trailers I have.

    – Greg Witek
  3. Amazing product. Frankly, this hitch is as professionally designed and quality built as they come! Don’t be surprised, it is a beast and worth it for anyone regularly hauling. My neck fatigue has been noticeably reduced since using this hitch. All the forward/back jerking is gone!

    – Alec Velazco
  4. I purchased the 16k 4.5 to 7.5 drop hitch great improvement over the other hitch’s I’ve got thanks a lot for improving the ride quality of my truck .

    – Steven Roosa
  5. Excellant hitch. I have 2 of them and they work flawlessly. They get rid of about 90 percent of the jarring of my enclosed trailer and car trailer. They are expensive, but worth it. My back doesnt smacked against the back rest of my seat. The worst roads I delt with this is on I94 and I43 thru Milwaukee, Wisconsin. Now with these hitches, I dont hurt any more.

    – Tony Harris
  6. I have purchased 2 of them. One for a 1990 GMC truck, and another for a 2019 Ford F350. It isnt a cheap or inexpensive hitch. But its well worth the money. It gets rid of 80 to 90 percent of the jarring you feel running down roads. It is easy to maintain, every so often you grease the pivot pin. The paint is very durable. The guy who usually answers the phone at shocker hitch is very knowledgeable and he will ask you for a few dimensions and when you get the hitch delivered you put the movable ball mount in their hitch, at the setting that he recommended and the trailer rides level just like it did before with the regular hitch. I would buy them again if I had to do it over again. They are well worth it. I have a small cigarette lighter powered air compressor to air up air bag when loaded up, so it can be adjusted anywhere on flat level ground. I think these hitches are excellent.
