5. Installation and Setup
This kit is designed for bolt-on installation. Refer to the included installation manual for detailed, step-by-step instructions specific to your vehicle model. Professional installation is recommended if you are not familiar with automotive suspension systems.
5.1. Pre-Installation Check
Before installation, ensure your vehicle's suspension is in its original configuration. If the rear of your vehicle is lifted, you may need an additional spacer to support the kit. If only the front of your vehicle is lifted, the kit will fit. The kit will not fit if both the front and rear of your vehicle are lowered.
Image: Visual guide on vehicle modification compatibility, indicating that the kit fits if the front is lifted, may require spacers if the rear is lifted, and does not fit if both front and rear are lowered.
5.2. General Installation Overview
The air springs are installed between the vehicle's frame and the rear axle. The air lines connect to the air springs and are routed to an accessible inflation point. Ensure all connections are secure and free from leaks.

6. Operation and Adjustment
The air springs are adjustable from 5 to 100 PSI. Adjust the air pressure based on the load being carried and road conditions to achieve optimal stability and comfort. Proper adjustment helps to:
- Prevent unbalanced loads
- Reduce bottoming out
- Keep headlights level
- Improve steering control and braking
- Preserve tires
- Eliminate sag
- Increase ride comfort

7. Maintenance
Regular inspection and proper maintenance are crucial for the longevity and performance of your air suspension system.
7.1. Preventing Leaks
To prevent air leaks, ensure that the air line ends are cut perfectly smooth and provide a tight seal when inserted into fittings. Verify that the air line is properly placed and routed, avoiding sharp bends or contact with moving parts. After installation, use a spray bottle filled with soapy water to check all fittings and the air bags for leaks. Bubbles will indicate a leak.

7.2. General Care
- Periodically check air pressure and adjust as needed.
- Inspect air lines and fittings for wear, damage, or corrosion.
- Clean the air springs and surrounding components to prevent dirt and debris buildup.
8. Troubleshooting
If you experience issues with your air suspension kit, consider the following:
- Loss of Air Pressure: Check all air line connections and the air bags for leaks using soapy water. Ensure valve caps are securely tightened.
- Uneven Ride Height: Verify that both air springs are inflated to the same pressure. Check for obstructions or damage to the suspension components.
- Poor Ride Quality: Adjust air pressure within the recommended range (5-100 PSI) to suit the load and road conditions.
