Shock Dampening Action: Shocker HD air hitch effectively absorbs the jerking, tugging and damaging forces experienced with a typical hard connection when towing trailers. There is no reason to beat yourself or your equipment up with a hard connection between your trailer and your receiver hitch.

Simple Pivot Design: uses a rocker arm pivot design which produces a down and back motion, much different than other air hitches on the market. Our design eliminates the need for slides, parallel linkages, rollers, shock absorbers, or multiple airbags common to other air hitches.

Improves Safety: By giving you improved control of your tow vehicle and trailer. The air bag receiver hitch system allows for better control of your pickup and the trailer it is towing.

Air Ride Hitch: Shocker Air is designed with a built-in air bag for a smoother towing experience. Featuring a built in height adjustment plus weight adjustable. Just add or ride air depending on the weight of your trailer and it’s contents.

Saves Money: By reducing trailer breakage on both the trailer and the trailer contents! The Shocker hitch absorbs the damaging forces experienced with a typical hard connection. This greatly reduces the chances of breaking welds and doing other long term damage to your equipment as well as the valuable cargo you have inside the truck and trailer.

Adds Life To Your Vehicle: By reducing wear and tear on driveline and frame! Treat yourself, your equipment, and your passengers to a much smoother ride. You’ll never go back to the ‘old days’ of continual bumps, jerks, and vibrations. Join the list of satisfied customers that are using Shocker hitches.

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.
  • Spacer block included and may be required when using 2″ shank (see spacer block install manual below)
  • It is highly recommended that the hitch ball be greased to reduce wear and improve shocker action.
  • DO NOT TIGHTEN THE TOP BOLT, IT IS A LIMITER STOP ONLY.

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

FAQ

Answers to Frequently Asked Questions

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.

How strong is the center pivot bolt?  The main pivot bolt with grease zerk, or center pivot bolt, used on the shocker air bumper hitch, is a custom made 1 inch diameter 1045 medium carbon steel bolt. Strategically heat treated to prevent wear and includes a machined grease passage for easy lubrication and maintenance. It should be noted that the yield strength of the 1″ pivot bolt exceeds the two 5/8″ bolts used to hold the typical ball coupler or receiver hitch.

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, GMC Dodge, Toyota, Nissan & Honda Pickups, Vans & SUV’s (SUV’s were the receiver is under the bumper). 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 or the receiver tube is inside the bumper.  The Shocker Air receiver hitch is available in a 2″, 2 1/2″ & 3″ shank.

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 with sway bars?
Yes, it works with the friction style sway control bar, however you want to order a ball mount with sway bar tabs. See our sway bar tab ball mount attachments.

How does the Air 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 long do the bump cushions last? This depends on if the hitch is left on the truck year round or not. If they bump cushions become mushy, you should replace them. Typical life expectancy is 5-7 years.

How much does an Shocker Air bag receiver hitch weigh? The Receiver Air Shocker weighs 50-55 pounds
