Replacement Valve

This replacement height control leveling adjustment valve is engineered for Peterbilt 379 trucks manufactured between 1987 and 1994, providing reliable air suspension system management. The valve features a 5-port design with dump capability, allowing precise height control and leveling adjustments for optimal vehicle performance and load distribution. The unit incorporates an 8-inch bent lever arm for responsive manual adjustment and operates with 1/4 inch NPT ports, ensuring compatibility with standard industrial pneumatic connections. Installation is straightforward with dual mounting studs that facilitate secure, efficient placement without requiring extensive modification to existing systems. The valve measures 22 inches in height, 1 13/16 inches in width, and 4 5/16 inches in length, making it suitable for the tight engine compartment spaces typical of classic Peterbilt configurations. This OEM replacement component is manufactured to original equipment specifications and includes PTC fittings and leveling valve hardware for complete system integration. Construction materials are selected for durability in commercial trucking applications, withstanding regular pressure cycling and environmental exposure common in long-haul operations. The leveling valve with integrated dump feature provides operators with manual control over suspension height, critical for maintaining proper chassis alignment, improving handling characteristics, and extending tire and suspension component life. This component serves as a direct replacement for original equipment, restoring full functionality to air suspension systems that have experienced valve degradation or failure. Ideal for fleet maintenance departments, independent truck repair shops, and owner-operators performing system restoration or preventive maintenance on classic Peterbilt 379 models.
