A Solution for Rough Rides

Have you ever hit a bump while towing and had that road shock jostle and shake you all the way down to your bones? It's a common feeling. Most couplers are made completely of metal, so there's nothing to help soften the shock when you hit a bump. This results in a bumpy, jerky ride that not only takes a toll on you as you drive, but it beats up your equipment too, leading to premature wear and tear on both your truck and trailer.

Fortunately, the Shocker Hitch Air coupler will change all of that.

Air Bag and Bumper Stop Shock Absorption Technology

Shocker Hitch Gooseneck Coupler

Using a built-in air bag and rubber cushions, the Shocker Hitch acts like a small suspension system between your truck and trailer. The air bag and bumpers help absorb road shock, creating a smoother, more comfortable ride while also protecting your truck and trailer from unnecessary wear and tear on the brakes, chassis, trailer frame, and suspensions.

Shocker Hitch Gooseneck Air Bag

The body of the Shocker Hitch Air coupler is designed to pivot back and forth on the pivot bolt, kind of like a teeter totter, as the air bag and the cushioned bumpers take turns absorbing the road shock. When you hit a bump and your trailer bounces, the unit pivots so that the air bag can isolate and absorb the energy. When your trailer jerks forward or backward, the 2 cushioned bumper stops help soften the force.

Customize Amount of Shock Absorption

Shocker Hitch Gooseneck Coupler

Using the easily accessible air valve on the top of the unit, you can adjust the air pressure in this Shocker Hitch coupler's air bag to best accommodate your trailer's load. If you're hauling heavy-duty landscaping equipment, for example, you can add air to account for the increased capacity. Once the equipment is unloaded, simply release some air so that your underloaded trailer won't experience a stiff ride.

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

Hi there I'm Michael with 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 Thanks for watching..
