4. Setup and Installation

Installation of this air suspension kit is designed to be straightforward, with pre-drilled holes and no drilling required for most applications. Automated tools can expedite the process.

4.1 Safety Precautions

• Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Ensure the vehicle is parked on a level surface and properly secured with wheel chocks.
• Safely raise and support the rear of the vehicle using jack stands before working underneath.
• Disconnect the vehicle's battery before starting any electrical work (if applicable for optional air compressor systems).

4.2 General Installation Steps (Refer to detailed guide for specific vehicle steps)

1. Prepare Vehicle: Safely lift the rear of the truck and support it with jack stands. Removing the rear wheels is highly recommended for better access to the frame and axle area.
2. Remove Existing Components: Remove any existing jounce bumpers or other components that occupy the space where the air bags will be installed.
3. Assemble Brackets and Air Bags: Attach the air bags to the upper and lower brackets according to the provided diagrams. Ensure air fittings are securely installed.
4. Mount Air Bag Assembly: Position the assembled air bag and bracket system between the vehicle's frame and axle. Secure the upper bracket to the frame and the lower bracket to the axle using the provided hardware.
   Note: Some F150 models (XLT, FX4, Lariat) may require minor slotting of mounting holes for proper alignment.
5. Route Air Lines: Connect the air tubing to the air fittings on the air bags. Route the air lines away from hot exhaust components, sharp edges, and moving parts. Secure the lines with zip ties.
6. Install Air Valves: Install the air inflation valves in a convenient and protected location, such as the bumper or fender well.
7. Check for Leaks: Inflate the air bags to approximately 50 PSI and spray all connections with a soapy water solution to check for air leaks. Tighten connections as necessary.
8. Lower Vehicle: Carefully lower the vehicle and remove jack stands.

5. Operating Instructions

The RETRUE air bags allow for customized air pressure adjustment to achieve optimal balance and ride comfort for various load conditions.

5.1 Air Pressure Adjustment

• Pressure Range: The air bags can be adjusted from 5 PSI (minimum) to 100 PSI (maximum).
• Load Leveling: Inflate the air bags to level the vehicle front-to-rear and side-to-side when carrying a load or towing a trailer.
• Ride Comfort: Adjust pressure to achieve desired ride comfort. Higher pressure provides more support for heavy loads, while lower pressure can improve unladen ride quality.
• Equal Pressure: For optimal performance and even load distribution, ensure both air bags are inflated to the same pressure. Consider using a T-fitting for simultaneous inflation.
• Check Pressure Regularly: Periodically check air pressure, especially before and during long trips, as temperature changes can affect pressure.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your air suspension system.

• Inspect Air Lines and Fittings: Periodically check all air lines and fittings for signs of wear, cracks, or leaks. Repair or replace damaged components immediately.
• Clean Air Bags: Keep the air bags clean from dirt, debris, and road salt. A mild soap and water solution can be used.
• Check Air Pressure: Maintain minimum air pressure (5 PSI) in the air bags at all times, even when unloaded, to prevent damage.
• Torque Check: Periodically check the torque of all mounting hardware to ensure they remain secure.
