    Setting Shocker Air Pressure for Trailer Tongue Mount Coupler

    To Set Air

    Load trailer the way it will be towed. Inflate airbag on Shocker Air Trailer Tongue Mount hitch. CAUTION: Keep hands and clothing away from moving parts of hitch to avoid pinching and injury. As air pressure increases, the unit will rotate lifting the hitch and trailer tongue. Install air until green bushing has 1/4″ clearance from the red frame. Always inflate air bag to set the Shocker Hitch, never deflate air bag to set Shocker Hitch, unsatisfactory results may occur. When using Equalizer/ Weight Distribution Hitch: Follow directions above, then hook up equalizer bars, and continue inflating air bag until 1/4″ clearance on bump stops is achieved. Note: When towing heavy trailers or trailers with high wind resistance it may be necessary to increase air pressure in the Shocker. Usage: Under normal circumstances, tongue weight should be at least 10 percent of the total towing weight. NOTE: IT IS HIGHLY RECOMMENDED THAT THE HITCH BALL BE GREASED TO REDUCE WEAR AND IMPROVE SHOCKER ACTION. Maximum Pressure: Do not exceed 100 psi in the air bag, as it may damage the air bag.

    FAQ

    Answers to Frequently Asked Questions

    What is the air trailer tongue mount tow rating? The HD air tongue mount model rating is up to 25,000 lbs GTW & 3,500 lbs Tongue Weight. The air tongue mount rating is rated up to 14,000 lbs GTW and 1,400 lbs tongue weight.. It must have an appropriately rated coupler or pintle ring for the rating to apply. Note: Tow capacity is limited by the lowest-rated component.

    How long will the air bag 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.

    Will this work with a W-D Hitch? Yes it will.

    How strong is the center pivot bolt?  The main pivot bolt with grease zerk, or center pivot bolt, used in the Tongue Mount Shocker air coupler, 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 on the average vertical channel adapter.

    Safety Notice: Note: Tow capacity is limited by the lowest-rated component.

    How much air do I put in the air trailer tongue mount? With your trailer hooked up to the tow vehicle, and loads positioned for transport, air up shocker air tongue until green bushing has 1/4″ clearance from the red frame. See install guide.

    How does it install? Simple bolt on installation in minutes. See install guide.

    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 do I know the Shocker Air trailer tongue mount with fit my trailer? We have 2 mounting options.  Square plate mount:  Simply bolts in place of existing coupler and has a 4-1/2″ square bolt pattern. Vertical channel mount: Simply bolts in place with existing trailer vertical channel for typical trailer couplers.  We do offer a weld on channel adaptor for your trailer tongue that can also be used if you don’t have one on your trailer.

    Does this affect my trailers ground clearance? No, the air bag is above the trailer tongue for maximum ground clearance

    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 Shocker air trailer tongue limited my tailgate with hooked up to the trailer? Maybe. It depends on your vehicles ball mount length. You can still open your tailgate, but it may rest on your air bag.

    How does the air ride trailer tongue coupler work? The 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.

    How much does an Shocker Air trailer tongue mount weigh? The Receiver Air Shocker weighs 60-70 pounds depending on model.

      Yes you are able to use both of them at the same time. It will not necessarily give you a smoother ride when doing this but they are able to work with each other.

      Yes, you can install a pressure gauge into the system if you would like. However, that gauge would not tell you the tongue weight on the trailer.

      Huge difference hauling a 20k lb backhoe bumper pull. Smoothed out the ride instead of shaking my trucks apart.

      – Alex Ewbank
    2. Rated 5 out of 5

      Once I put enough air in the bladder, my trailer felt like it wasn’t even there. I transport a variety of items with various weights and the ability to adjust the pressure on the fly is great.

      – Samuel Van Brunt
    3. Rated 5 out of 5

      Wow what a difference! Started with no air after easily mounting the hitch in the trailer hitch channel. The ride was surprisingly rough . I had a Colorado with an empty trailer that weighed 4800#. I aired the bag when I found an air source. It really smoothed out the ride. 65 mph all the way home. Hardly any Interstate – all back roads. This hitch will really make difference in comfort and smoothness. 5/5 stars!

    4. Rated 5 out of 5

      Ive got this hitch on my 24k, 3 axle, bumper pull trailer. It is unbelievable how much the trailer is bouncing and moving about while the truck stays relatively smooth. This is my third trailer I have equipped with a shocker hitch and I definitely swear by them.

      Great service from Bob and his crew with install and setting up the proper angle of my trailer. I’ve only used it a little from their shop to the farm and I notice a great improvement.

    8. Rated 5 out of 5

      I installed the Tongue Mount Coupler on my 14K bumper pull tilt deck trailer. Before, there was constant jerking. It did not matter if there was a load or not. Afterwards, it pulls so much smoother! It took so much of the tugging, jerking, and bouncing out.

      I ordered on a Saturday and recieved it the following Wednesday . The technicians and owner have been extremely helpful with advice concerning position and air pressures . The hitch does a great job of getting rid of the bone rattling bumps when you tow a heavy duty trailer with hard springs and extreme tires. This hitch is built by Americans who understand what we do with it on the road and take pride in their workmanship !

      It does precisely what they say it does. Installation was a breeze. It tamed my tandem axle car hauler. Only wish I had it 20 years ago. Going to buy two more for my two gooseneck trailers.

      So far, so good. Definitely smooths out the ride and less jarring and bumping towing my 7 ton dump trailer. Thanks for a great product.

    13. Rated 5 out of 5

      This is one of those products you buy and say to yourself, “man I’d pay double that” it really does make that much a difference, I have a 28,000# service truck that pulls a 10,000# parts trailer. Things were constantly being rearranged before but now nothing moves. I put on anywhere from 300 to 1,500 miles a week. Now I certainly do find roads that I could have a 4 link at each wheel and still would throw you out your seat but those are far few between, you will be amazed at the difference if you have issues. If you pull a trailer on a regular basis I highly recommend.

      I can’t believe how smooth this thing is when pulling a trailer. I am an on the road salesman and I pull a 24ft enclosed trailer on a daily basis. I have about four to five thousand pounds in the trailer on average. Its attached to a 2008 Chevy 2500 ext cab long bed Duramax w/Allison. Its like the trailer is not even back there. The truck actually rides smoother with the trailer on than off. Amazing product!!
