Setup and Installation

Installation of the maXpeedingrods air suspension kit requires mechanical aptitude and proper tools. It is recommended to have the installation performed by a qualified professional if you are not confident in your abilities. Always refer to the detailed installation guide provided with your kit for specific step-by-step instructions.

General Installation Guidelines:

1. Safety First: Ensure the vehicle is securely lifted and supported on jack stands. Disconnect the battery if working near electrical components.
2. Prepare the Area: Clean the mounting surfaces on the vehicle's frame and axle to ensure proper fitment of brackets.
3. Mount Brackets: Install the upper and lower mounting brackets according to the vehicle-specific instructions. Ensure all bolts are tightened to the manufacturer's specifications.
4. Install Air Bags: Carefully position and secure the air suspension bags between the mounted brackets.
5. Connect Air Lines: Attach the air lines to the elbow air fittings on the bags. Ensure a clean, straight cut on the air line for a proper seal.

6. Install Inflation Valves: Mount the inflation valves in an accessible location, typically near the rear bumper or in the wheel well.
7. Route Air Lines: Route the air lines away from hot exhaust components, sharp edges, and moving parts. Secure them with zip ties or clips.
8. Leak Test: After installation, inflate the bags to a moderate pressure (e.g., 50 PSI) and perform a leak test using a soap and water solution. Spray all fittings and the bag itself; look for bubbles.
9. Final Check: Double-check all connections and hardware for tightness before lowering the vehicle.

Preventing Leaks:

• Ensure the air line is cut perfectly smooth and straight to create a tight seal with the fittings.
• Verify that the air line is properly placed and routed without kinks or sharp bends.
• Use a spray bottle filled with soap and water to spray down all fittings and the air bag itself. Any bubbles indicate a leak that needs to be addressed.

Operating Instructions

The maXpeedingrods air suspension kit allows for adjustable air pressure to optimize your vehicle's ride quality and load support.

Adjusting Air Pressure:

1. Determine Load: Assess the weight of the cargo or trailer you are carrying.
2. Inflate/Deflate: Use an air compressor (not included) to inflate the air bags via the inflation valves. For deflation, simply press the valve stem.
3. Recommended Pressure Range: The air bags are adjustable from 5 PSI (minimum) to 100 PSI (maximum).
   • Light Loads/Unloaded: Maintain a minimum of 5-10 PSI to prevent damage to the bags.
   • Heavy Loads: Increase pressure as needed to achieve a level stance and comfortable ride, up to 100 PSI. Do not exceed 100 PSI.
4. Monitor Ride Height: Adjust pressure until the vehicle achieves a level stance, which helps maintain proper headlight aim and reduces tire wear.
5. Test Drive: After adjusting, take a short test drive to ensure the desired ride quality and stability are achieved. Make further small adjustments if necessary.

Benefits of Proper Adjustment:

• Protects cargo from shifting.
• Prevents unbalanced loads.
• Reduces bottoming out over bumps.
• Keeps headlights level for improved visibility.
• Increases overall ride comfort.
• Improves steering control and braking performance.
• Preserves tire life by ensuring even wear.
• Eliminates vehicle sag.

Maintenance

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

• Regular Inspection: Periodically inspect the air bags, air lines, and fittings for any signs of wear, cracks, chafing, or leaks.
• Check Air Pressure: Check the air pressure in the bags regularly, especially before and after hauling heavy loads. Adjust as necessary.
• Clean Components: Keep the air bags and surrounding components clean from dirt, debris, and road salt, which can degrade materials over time.
• Tighten Hardware: Occasionally check all mounting bolts and nuts for tightness and re-torque if necessary.
• Avoid Over-Inflation/Under-Inflation: Always operate the air bags within the recommended pressure range (5-100 PSI) to prevent damage.
