How to Air Up Gooseneck Surge Air Coupler?

This is a LOW-PRESSURE hitch, that works by tow resistance.
Set air pressure at approx. 15 psi, then test drive.
Increase pressure in 5 psi increments until optimum results are found.
Typical air pressure range is 15 – 25 psi.
Note: When towing heavy trailers or trailers with high wind resistance it may be necessary to increase air pressure in the Shocker.
Maximum Pressure: Do not exceed 100 psi in the air bag, as it may damage the air bag.

Installation
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
Remove pins or loosen locking bolts on the trailer frame sleeve, and remove the existing coupler tube.
Slide Gooseneck Surge Shocker Hitch insert tube inside the trailer frame sleeve with the air bag toward the rear of trailer.
Hold or support Shocker at vertical measurement noted in Step #1. This should duplicate the previous ride height of the trailer. Shocker hitch 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 Shocker hitch insert tube and have a qualified machine shop drill / machine the pin holes.
Torque locking bolts to your trailer manufacturers’ recommended specifications. A spacer kit is available for some applications.
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! )
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.
