Installation

1. Take a vertical measurement from bottom of ball coupler tube to bottom of trailer frame sleeve. This dimension will be used to set the Shocker Gooseneck Surge Trailer Hitch
2. Remove pins or loosen locking bolts on trailer frame sleeve, and remove existing coupler tube.
3. Slide Gooseneck Surge Shocker Hitch insert tube into trailer frame sleeve with air bag toward 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 trailer by simply lowering coupler onto the ball. (Handle will snap open & shut automatically). To release trailer: Pull handle up and hold while raising trailer.
