Setup and Installation
The RETRUE Air Bags Suspension Kit is designed for straightforward installation with pre-drilled holes, requiring no drilling for most applications. Comprehensive instructions are included to guide you through the process.
General Installation Steps:
- Prepare Vehicle: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Lift the rear of the vehicle and support it with jack stands.
- Remove Existing Components: Follow the specific instructions for your vehicle model to remove any existing bump stops or other components that interfere with the air bag installation.
- Assemble Air Bags and Brackets: Attach the air bags to the upper and lower mounting brackets using the provided hardware. Ensure all connections are secure.
- Install Assembly: Position the assembled air bag and bracket unit between the vehicle's frame and axle. Ensure adequate space and no interfering components in this area.
- Secure Brackets: Fasten the upper and lower brackets to the vehicle's frame and axle using the supplied bolts, nuts, and washers. Torque all fasteners to the specifications provided in the detailed instructions.
- Route Air Lines: Connect the air lines to the air bags and route them to a convenient location for inflation, such as the rear bumper or fender well. Secure the air lines using zip ties to prevent rubbing or damage.
- Install Air Fittings: Attach the air fittings to the end of the air lines. Ensure a tight seal.
- Lower Vehicle and Test: Carefully lower the vehicle. Inflate the air bags to the recommended minimum pressure (5 PSI) and check for any air leaks using a soapy water solution.
Tip: Using automated tools can significantly speed up the installation process.

Operating Instructions
The RETRUE Air Bags Suspension Kit allows for customized air pressure to achieve optimal load leveling and ride comfort.
Adjusting Air Pressure:
- The air bags can be fine-tuned with air pressure ranging from 5 to 100 PSI.
- For light loads or unloaded driving: Maintain a minimum of 5 PSI to prevent damage to the air bags.
- For heavy loads or towing: Increase air pressure as needed to level the vehicle front-to-rear and side-to-side. Adjust pressure until the vehicle is level and the ride is comfortable.
- Do not exceed 100 PSI.
Proper air pressure adjustment helps to reduce sag, improve steering control, enhance braking effectiveness, and minimize bottoming out, providing a safer and more comfortable towing experience.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your RETRUE Air Bags Suspension Kit.
- Check Air Pressure: Periodically check the air pressure in your air bags, especially before and after towing or hauling heavy loads. Maintain a minimum of 5 PSI at all times, even when unloaded.
- Inspect for Leaks: Annually, or if you notice a drop in pressure, inspect the air lines and fittings for leaks using a soapy water solution. Tighten connections or replace components as necessary.
- Examine Air Bags: Visually inspect the air bags for any signs of wear, cracks, punctures, or abrasion. Ensure they are free from debris and not rubbing against other vehicle components.
- Clean Components: Keep the air bags and surrounding components clean from dirt, salt, and road grime.
- Torque Check: Periodically check the torque of all mounting hardware to ensure they remain securely fastened.
Troubleshooting
This section addresses common issues you might encounter with your air bag suspension kit.
| Problem | Possible Cause | Solution |
|---|---|---|
| Air bags lose pressure quickly. | Air leak in lines, fittings, or air bag. | Spray all connections and air bag surfaces with soapy water. Look for bubbles. Tighten fittings, replace damaged air lines, or replace a faulty air bag. |
| Vehicle remains low or sags. | Insufficient air pressure; air bags not inflated enough for the load. | Increase air pressure to level the vehicle. Ensure pressure does not exceed 100 PSI. |
| Uneven vehicle height (side-to-side). | Uneven air pressure in left and right air bags; uneven load distribution. | Adjust air pressure in individual air bags to level the vehicle. Redistribute load if possible. |
| Rough or stiff ride. | Too much air pressure for the current load. | Reduce air pressure until a comfortable ride is achieved, ensuring a minimum of 5 PSI is maintained. |
