1. Compressing Air Spring (BEFORE INSTALLATION)

• Release Pressure: Use the provided cotter pin clip to push in on the valve core to release air pressure from the back.

• Compress: While releasing pressure, simultaneously push down on the air spring paddle or squeeze the plates together to exhaust the remaining air.

2. Installing the Shocker Hitch into the Receiver

• Mounting: Slide the hitch shank fully into the receiver tube of your tow vehicle.

• Align and Secure: Align the pin holes and insert the 5/8” hitch pin. Lock it in place with the cotter pin clip.

3. Install Attachment Ball Mount

• Selection: Choose an attachment that allows your trailer to sit level. Refer to “WHAT SIZE DROP HITCH DO I NEED” and “GROUND CLEARANCE GUIDE” for more information.

• Attachment: Install your chosen mount into the Shocker Hitch Frame.

• Secure: Use the hitch pins and cotter pin clips provided to lock the ball mount into place.

4. Setting Air Pressure

• Load the Trailer: Hook up your trailer and load it as you normally would for travel.

• To Set Air: Hook up trailer using a properly selected ball adaptor and height adjustment to level trailer when loaded. Next, inflate the air spring. As air pressure increases, the unit will rotate, lifting the hitch point. Install enough air until the top of the hitch frame touches the top (tailgate side) bump cushion, or for heavy loads, until it compresses the tailgate side bump cushion by approximately 1/8″.

The “Sweet Spot”

Stop adding air once the main frame lightly compresses the truck side bump cushion.

Spacer Block Guide

How do I know if I need a spacer block on my air receiver hitch? How do I know if I need a spacer block on my air receiver hitch? When your air receiver and trailer are hooked up, and the air receiver has the proper air pressure, the metal paddle above the air spring bag should be level with the air spring bag. If the paddle has more than a 10-degree angle when the air receiver hitch is aired up, a spacer block can be installed on top of the paddle to level the paddle and air spring bag. A spacer is needed when the angle between the bottom of the vehicle receiver and the top paddle above the air spring bag on the hitch is excessive. (A spacer block is used with 20K HD Air Receiver Hitches with a 2″ receiver (already installed) and some HD air receiver hitches with a 2-1/2″ receiver (Spacer comes in box). It is generally not ever needed with a 14K air receiver hitch, as the air spring bag is 1″ taller than the HD air spring bag.)

Safety Notice: NEVER exceed 100PSI, as this can damage the air spring or bushings.
