5.3. Vehicle Mounting
- Carefully position the assembled air spring and bracket onto the vehicle's leaf spring.
- Secure the lower bracket to the leaf spring using the provided U-bolts and hardware. Ensure all bolts are tightened securely.
- Attach the upper bracket to the vehicle's frame using the appropriate bolts and hardware.
- Connect the air lines to the air fittings on the air springs. Route the air lines to a convenient location for inflation, ensuring they are clear of moving parts and heat sources.
- Inflate the air springs to a minimum of 5 PSI using an air compressor or manual pump.
- Check all connections and air lines for leaks using a soapy water solution. Bubbles indicate a leak.
- Once confirmed leak-free, reinstall the rear wheels and lower the vehicle.
6. Operating Instructions
- Air Pressure Adjustment: The air springs are adjustable from 5 to 100 PSI. Adjust the pressure based on the load being carried and road conditions to achieve optimal ride height and comfort.
- Loading: Always add air pressure to the springs before adding a load to the vehicle. This prevents the springs from bottoming out and ensures proper load distribution.
- Minimum Pressure: Maintain a minimum of 5 PSI in the airbags at all times, even when unloaded, to prevent damage to the air springs.
- Towing/Hauling: For heavy loads or towing, increase air pressure to level the vehicle, reduce squat, minimize trailer sway, and improve steering control and braking.

7. Maintenance
- Regular Pressure Checks: Check air pressure regularly, especially before and after hauling or towing, and adjust as necessary.
- Inspect Components: Periodically inspect the air springs, air lines, and all mounting hardware for any signs of wear, damage, or corrosion.
- Cleanliness: Keep the air springs and surrounding components clean from dirt, debris, and road salt to prolong their lifespan.
8. Troubleshooting
- Air Leakage: If you notice a loss of air pressure, check all air line connections and the air springs themselves for leaks using a soapy water solution. Tighten loose fittings or replace damaged components.
- Uneven Ride Height: Adjust the air pressure in individual air springs to achieve a level ride. Ensure both sides are inflated to the appropriate pressure for the load.
- Reduced Performance: Verify that the air pressure is within the recommended 5-100 PSI range. Inspect for any obstructions or damage to the air springs or mounting hardware.
