5. Safety Information

Always observe the following safety precautions during installation and operation:

Professional Installation Recommended: Due to the complexity of vehicle suspension systems, professional installation by a qualified mechanic is highly recommended.
Vehicle Support: Always ensure the vehicle is properly supported on jack stands or a lift before working underneath it. Never rely solely on a jack.
Personal Protective Equipment: Wear appropriate safety glasses, gloves, and other personal protective equipment (PPE) during installation.
Air Pressure: Never exceed the maximum recommended air pressure of 100 PSI for the air springs. Maintain a minimum of 5 PSI at all times to prevent damage.
Electrical Connections: Ensure all electrical connections are secure and properly insulated to prevent short circuits and electrical hazards. Disconnect the vehicle's battery before working on electrical components.
Air Line Routing: Route air lines away from sharp edges, hot exhaust components, and moving parts to prevent damage and leaks.
Load Capacity: Do not exceed the vehicle's Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR), even with the air suspension installed. The air suspension assists with leveling and ride quality, but does not increase the vehicle's load-carrying capacity beyond its factory ratings.

6. Setup and Installation

This kit is designed for a straightforward installation process with no drilling required for the air springs. However, proper routing of air lines and electrical wiring for the compressor is crucial.

General Installation Steps (Consult a professional if unsure):

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 securely with jack stands. Remove the rear wheels if necessary for access.
Remove Existing Components: Follow vehicle-specific instructions to remove any existing bump stops or components that interfere with air bag installation.
Install Air Springs: Position the air springs with their mounting plates according to the vehicle-specific instructions. Secure them using the provided hardware. Ensure the air bags are properly seated and aligned.
Route Air Lines: Connect the air lines to the air springs. Route the air lines away from hot exhaust, sharp edges, and moving suspension components. Secure them with zip ties.
Mount Compressor and Gauge Panel: Choose a suitable location for the 12V MXR Air Compressor, ideally protected from road debris and moisture (e.g., under the truck bed, inside the frame rail). Mount the gauge panel inside the vehicle's cabin in an accessible location.
Wire Compressor: Connect the compressor to the vehicle's electrical system according to the wiring diagram provided with the kit. Ensure proper fusing and relay connections. Connect the gauge panel wiring to the compressor.
Connect Air Lines to Compressor: Connect the routed air lines from the air springs to the compressor's manifold or T-connectors, and then to the gauge panel. Ensure all connections are tight and leak-free.
Test System: Once all components are installed, lower the vehicle. Inflate the air springs to the recommended operating pressure (5-70 PSI) and check for any air leaks using a soapy water solution. Verify the compressor and gauge panel function correctly.

7. Operating Instructions

The on-board air compressor system allows for convenient adjustment of air pressure from the driver's seat.

Adjusting Air Pressure:

Inflation: To increase air pressure, press the 'Up' button on the gauge panel. The compressor will activate and inflate the air springs. Monitor the gauge to reach the desired PSI.
Deflation: To decrease air pressure, press the 'Down' button on the gauge panel. Air will be released from the springs.
Recommended Pressure: Maintain a minimum of 5 PSI in the air springs at all times, even when unloaded. For loaded conditions, adjust the pressure between 5 PSI and 70 PSI to achieve a level ride and optimal comfort. Never exceed 100 PSI.
Single Path System: This system inflates both air springs simultaneously, ensuring even pressure distribution and a balanced ride.

8. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your air suspension system:

Inspect Air Lines: Periodically check all air lines for kinks, chafing, or signs of wear. Ensure they are securely fastened and away from heat sources or moving parts.
Check for Leaks: At least once a month, or before long trips, check the entire system for air leaks using a soapy water solution. Spray connections, air bags, and fittings. Bubbles indicate a leak.
Clean Compressor: Keep the air compressor free of dirt and debris. While it has a waterproof case, excessive buildup can affect performance.
Maintain Minimum Pressure: Always maintain at least 5 PSI in the air springs to prevent damage to the internal components and rubber.
Inspect Air Bags: Visually inspect the air bags for any signs of cracking, dry rot, or physical damage.

9. Troubleshooting

If you encounter issues with your air suspension system, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Air springs do not inflate or deflate	No power to compressor; Blown fuse; Loose electrical connection; Compressor malfunction; Air line blockage.	Check vehicle's fuse box; Verify all electrical connections are secure; Test compressor for power; Inspect air lines for kinks or blockages.
Air springs lose pressure over time	Air leak in system (fittings, air lines, air bag); Damaged air bag.	Spray soapy water on all connections and air bags to locate leaks. Tighten fittings or replace damaged components.
Compressor runs but air springs do not inflate	Air line disconnected or severely kinked; Compressor not producing sufficient pressure.	Check all air line connections; Inspect air lines for severe kinks; Consult a professional if compressor output is low.
Vehicle remains unlevel after inflation	Uneven load distribution; One air spring under-inflated or leaking.	Adjust load distribution; Check individual air spring pressures and inspect for leaks on the lower side.
