We perfected that and never considered the other benefits. Customers using the Surge hitch started calling with reports of better fuel mileage. Claims of up to a mile per gallon are pretty normal.

Adds Life To Your Vehicle & Gooseneck: 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.

Installation

  1. Take a vertical measurement from the bottom of the ball coupler tube to the bottom of the trailer frame sleeve. This dimension will be used to set the Shocker Gooseneck Surge Trailer Hitch
  2. Remove pins or loosen locking bolts on the trailer frame sleeve, and remove the existing coupler tube.
  3. Slide Gooseneck Surge Shocker Hitch insert tube inside the trailer frame sleeve with the air bag toward the rear of trailer.
  4. Hold or support Shocker at vertical measurement noted in Step #1. This should duplicate the previous ride height of the trailer. Shockerhitch must be properly aligned, (parallel with trailer), to maximize its benefits.
    Note: If your trailer coupler tube is equipped with a pin or pins, the correct pin location must be marked in the Shockerhitch insert tube and have a qualified machine shop drill / machine the pin holes.
  5. Torque locking bolts to your trailer manufacturers’ recommended specifications. A spacer kit is available for some applications.
  6. Lubricate: Oil the coupler shaft, grease coupling ball socket, and grease the hitch ball to REDUCE WEAR AND IMPROVE SHOCKER ACTION. Main pivot grease zerk should be greased periodically for maximum bushing life. ( Simply, you cannot over-grease it! )
  7. Hook up the trailer by simply lowering the coupler onto the ball. (Handle will snap open & shut automatically). To release trailer: Pull handle up and hold while raising trailer.

What do your mean when you say straight or angled / slotted pin holes?  We are wondering if your gooseneck stem has holes that are straight across OR if it is slightly angled 10-30 degrees, where the stem hitch pin is off set or at an angle. Below is a picture of an angled stem, which we would use a stem with slotted holes to fit this angled pin.

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.

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.

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.
