Shocker Air Receiver Hitch Installation Instructions
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.
• 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 decision guide
Check alignment with your trailer connected, loaded for travel and the air pressure correctly set. The paddle above the air spring should be approximately parallel with the receiver tube.
When is a spacer block needed?
1. Correct alignment Paddle approximately parallel with the receiver tube. A spacer is not needed to correct the angle shown.2. Excessive angle If the paddle angle is more than 10 degrees with pressure correctly set, follow the spacer-block guidance for your model.3. Corrected alignment The spacer sits on top of the paddle against the underside of the receiver tube, correcting the excessive angle.
Model notes: 20K HD hitches with a 2-inch receiver come with the spacer installed. Some HD models with a 2-1/2-inch receiver include it in the box. A spacer is generally not needed on 14K air receiver hitches because their air spring is 1 inch taller than the HD air spring.
Maximum air pressure: 100 PSI. Do not use extra air pressure to exceed this limit while checking alignment. Read the full spacer-block guide.

• Attachment: Install your chosen mount into the Shocker Sport Hitch Frame.
• Secure: Use the hitch pins and cotter pin clips provided to lock the ball mount into place.
4. Setting Air Pressure

Trail Force Receiver Hitch Installation Instructions
1.Installing the Trail Force Air 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.
• Attachment: Install your chosen mount into the Trail Force Hitch Frame.
• Secure: Use the hitch pins and cotter pin clips provided to lock the ball mount into place.
3. Setting Air Pressure

Air receiver hitch troubleshooting
Start with your trailer connected and loaded for travel. Follow the instructions for your model above; do not use extra air pressure or bolt adjustments to compensate for an incorrect setup.
The ride feels stiff
Recheck the air setting against the truck-side bump cushion rather than aiming for a preset PSI. The main frame should lightly compress that cushion. Check routine lubrication, too.
Do not tighten the top jamnut bolt (limiter bolt). If it has already been adjusted, contact our team before making further adjustments.
A changed trailer load, temperature change or a new air spring settling can affect pressure. Recheck the loaded setup. Persistent or substantial pressure loss needs a leak check; use the air receiver section of our detailed guide.
Never inflate an air spring outside its hitch frame. If the spring will not hold air or appears damaged, contact our team before towing.
With air pressure correctly set, compare your setup with the three alignment examples. The paddle above the air spring should be approximately parallel with the receiver tube. Spacer requirements depend on the model and receiver size.
Routine Lubrication • Pivot Bolt: Regularly grease the Shocker Hitch unit using the built-in grease zerk located on the main pivot bolt. • Over-Greasing: You cannot over-grease the unit; frequent lubrication ensures the air-ride pivot remains fluid and responsive. • Hitch Ball: It is highly recommended to grease the trailer coupler ball to reduce friction and prevent premature wear.
Critical Adjustments • Top Jamnut Bolt: DO NOT tighten the top jamnut bolt. • Factory Specs: This bolt is set to factory specifications out of the box; overtightening will cause a stiff towing experience and limit the airbag’s effectiveness. • Attachment Swapping: When changing between different ball mounts (Combo, Pintle, Clevis, etc.), ensure the pins and cotter pin clips are fully seated and locked.
Air System Integrity • Max Pressure: Never Exceed 100PSI in the air spring. • Component Protection: Excessive pressure can lead to permanent damage to the air spring or the internal bump cushions. • Pre-Tow Inspection: Always check your air pressure after loading the trailer to ensure the frame is lightly compressing the bump cushion.
Quick answers for standard and HD air receivers, Sport™ and Trail Force® models.
How much air pressure should I use?
There is no single PSI setting for every trailer. With the trailer connected and loaded, add air until the main frame lightly compresses the truck-side bump cushion, following your model’s steps. Recheck after changing the load. 100 PSI is the maximum, not the target.
Use the air valve shown for your model. Watch the cushion nearest the truck, also called the tailgate-side cushion. The paddle is the flat steel plate above the air spring; the limiter bolt is not an air-pressure adjustment.
Check the paddle angle with the trailer loaded and air pressure set. An angle greater than 10 degrees calls for reviewing the spacer guidance for your model. The 20K HD with a 2-inch receiver comes with the spacer installed; some HD 2-1/2-inch models include it in the box. A spacer is generally not needed on 14K air receivers.
How do I choose the receiver size and ball-mount height?
Measure the inside opening of your vehicle’s receiver and match the hitch shank to it. Select a ball mount with enough drop or rise to keep the loaded trailer level, then check ground clearance.
Can I use a weight-distribution hitch or friction sway control?
The air receiver hitches covered here are not for use with a weight-distribution system. See the Shocker Air Equalizer for that application and confirm compatibility with your setup. Friction sway control requires the appropriate sway-bar-tab ball mount and compatible sway-control components; it is a different setup from weight distribution.
No. Stay within the vehicle, receiver, hitch, ball mount, ball, coupler and trailer ratings. The lowest-rated component limits the setup, including its applicable tongue-weight limit.
Check that the receiver pin, attachment pins and their retaining clips are fully secured; the coupler is locked on the correct ball; and the safety chains and electrical connection are in place. Confirm loaded trailer height, ground clearance and air adjustment, then complete the full pre-tow checks.
How do I choose a replacement air spring or cushion?
Match the part to your exact hitch model and air-valve or air-line configuration. Do not select by appearance alone. Use the replacement-part links on this page, or send our team your model number and a photo before ordering.
