This trailer tongue coupler adds air ride technology to your trailer, dampening chucking and road shock. Air bag and bump stops work with the 2-5/16" heavy-duty EZ-Latch coupler to reduce destructive forces on your trailer and tow vehicle.


Features:

  • Shock-absorbing trailer coupler features industrial strength air bag and cushioned bump stops to dampen chucking and road shock
  • Air hitch works like a teeter-totter with the air bag on one end, and your trailer coupler on the other end
    • As your trailer exerts force upward, downward, backward, or forward, the unit pivots and the air bag and bump stops absorb the energy for a smoother ride
    • Grade 50 steel plate construction is shot blasted and powder coated to prevent rust
  • Easily adjustable air bag - for heavier loads, add more air; for lighter loads, let air out
  • Zerk-fitting at the pivot point makes maintenance simple
  • Includes Demco 2-5/16", 21K-rated EZ-Latch coupler
    • Lets you hook up when latch is in closed position - just drop coupler over hitch ball and latch will snap into place
    • Red powder coat primed paint finish offers excellent corrosion resistance
  • Fits trailers with a square plate 4 bolt mount with 4-1/2" square bolt pattern
  • Made in the USA


Specs:

  • Application: Square plate 4 bolt mount with 4-1/2" square bolt pattern
  • Gross towing weight: 20,000 lbs
  • Tongue weight: 2,000 lbs
  • Ball size: 2-5/16"
  • 1-Year warranty


Note:

  • The main pivot bolt, or center pivot bolt, used in the Tongue Mount Shocker air coupler is a custom made 1" diameter 1045 medium carbon steel bolt. Strategically heat-treated to prevent wear, it 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 adaptor.

Video Transcript for Review of Shocker Hitch A-Frame Trailer Coupler - Air Coupler - SHK83RR

Hi there I'm Michael with etrailer.com. Today we're going to take a quick look at this shocker trailer tongue air coupler. This is a shock absorbing trailer coupler. That's going to feature this industrial strength airbag as well as these cushion bump stops to help damping that chucking and road shock that you often get as you're towing your trailer. This is going to fit trailers with a square plate, four bolt Mount with a four 1/2 inch square bolt pattern. This will also feature the Demco two and five 16th inch easy latch coupler, and that will allow you to very easily connect to your two and five 16th inch hitch ball on your vehicle.

You're not going to have to raise this into the open position, stays in the closed position. As you lower it onto the hitch ball, it's going to lock in place. And then when you're ready to remove it, then you'll move it to the open position and lift up your coupler and it will disengage from that ball. So very very easy to get hooked up there. The way this works it's kind of like a Teeter totter with the airbag on the one end and then the trailer coupler on the other.

So as your trailer gets force upward, downward, back and forth, the unit is going to pivot then the airbag and bump stops are going to help absorb that energy for a smoother ride. It's going to be a lot more comfortable for you up in your tow vehicle, and this is easily adjustable. So you've got your air spigot right there. So you can air that airbag up for heavier loads or for lighter loads you can easily let the some air out. This is going to be capable of a gross towing weight of 20,000 pounds.

That's the weight of the trailer Plus the load included and a maximum tongue weight of 2000 pounds, which is of course the downward pressure on your hitch ball. The main pivoting bolt here is a custom made one inch diameter, 10 45, medium carbon steel bolt that's been strategically heat treated to help prevent wear. So this is actually going to yield, have a yield strength that exceeds your 2, 5, 8 inch bolts that are typical for your ball couplers on the average vertical channel adopter. So this is actually going to be a lot stronger, even though it's just the single bolt. On the backside here, you can see, they do have that built-in grease, grease zerk and the grease passage, and that's going to make it very easy to keep that lubricated and maintained.

Our steel plates, here are a grade 50 steel plate construction. So they are going to be very durable for you. They are shot blasted and powder coated to help resist rust and corrosion. So it's going to hold up really well, give you that nice, comfortable shock absorption as you're going down the road. And that is made here in the USA. So you can trust it's made it to the high quality standards that we've come to know and trust for products that are made here in the US. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..
