The Freightliner 18-51378-000 Cab Link Kit Leveling Valve restores proper operation of the cab air-ride leveling system. This OEM-spec linkage transfers suspension movement to the leveling valve, allowing it to adjust air pressure and maintain a stable ride height. Worn or damaged linkages can cause uneven cab movement, harsh rides, or incorrect leveling. This replacement installs easily and ensures reliable feedback for the cab suspension valve, improving comfort and system lifespan.

Specifications

Freightliner’s 18-51378-000 Cab Link Kit Leveling Valve is designed to provide accurate linkage between the cab suspension geometry and the leveling valve, ensuring proper height control and smooth operation of the air-ride cab system. As cab suspensions cycle through load, road vibration, and chassis movement, the feedback link is critical for maintaining consistent cab height and reducing driver-perceived vibration. A worn or stretched link can lead to incorrect valve actuation, poor cab leveling, and accelerated wear of suspension components. This OEM-equivalent kit is engineered for durability, proper fit, and long service life.
