6. Instruccions de funcionament
The maXpeedingrods air helper spring bags are designed to provide adjustable load support and improve ride quality.
6.1 Load Leveling
These air springs offer up to 5,000 pounds of load leveling capacity. When towing or hauling heavy loads, inflate the air springs to prevent the rear of the vehicle from squatting or bottoming out. This helps maintain proper vehicle stance, improves steering control, and reduces wear on other suspension components.

6.2 Internal Jounce Bumper
The air springs feature an internal jounce bumper. This component prevents the air spring suspension kit from being fully compressed during impacts caused by heavy objects, potholes, curbs, or other road hazards. This design protects the air spring and provides a smoother ride by absorbing extreme compression forces.

6.3 Air Pressure Adjustment
- Adjust air pressure as needed based on load and desired ride height.
- Do not overinflate or underinflate the air springs. Refer to your vehicle's specific recommendations or the air spring's maximum/minimum pressure ratings.
- Always inflate or deflate air springs with the vehicle on a level surface and the wheels on the ground.
7. Manteniment
Regular maintenance ensures the longevity and optimal performance of your air helper spring bags.
