Our leveling valve is a direct replacement for OEM part number KD2291 and is specially designed for air suspension systems commonly used in heavy-duty trucks. Our air leveling valve is compatible with Barksdale and Freightliner models. This valve plays a crucial role in adjusting and maintaining the vehicle's suspension height. It ensures optimal load distribution and driving comfort in trucks. The trailer leveling valve comes with Push-to-Connect (PTC) fittings which simplifies installation and maintenance by allowing easy connection of air lines. The other important information about the leveling valve is as mentioned below:
Application: The leveling valve regulates the airflow in the vehicle's air suspension system, and controls the suspension height by adjusting the air pressure. It also prevents uneven weight distribution, enhances ride stability, and improves handling, especially when carrying heavy loads. It will also help you to maintain the performance and safety of trucks, and ensure that the vehicle's height remains constant under varying load conditions.
Push-to-Connect Feature: Our leveling valve comes with 1/4" PTC fittings for the supply, suspension, and exhaust ports. These fittings simplify the connection process and allow for easy and tool-free installation or replacement, reducing the risk of leaks or improper connections.
No Delay Operation: The trailer leveling valve is designed for immediate responsiveness. It operates without a delay and ensures real-time adjustments to the suspension height. This feature helps maintain consistent driving performance, particularly under shifting loads or road conditions.
Compatibility: This valve is compatible with Barksdale, and Freightliner. It works well in air suspension systems and ensures accurate suspension control for heavy-duty applications.
