For Cab or Front Air Suspension Applications

Link’s 600 series is a light duty height control valve manufactured to OEM fit, form, and function. The valve is a universal replacement for most heavy duty cab and front air ride suspensions. Each valve is made of high-quality materials and 100% factory line tested for reliable performance. Drivers and fleets benefit from the valve’s precise adjustment of ride height variation, easy bolt-on application, and ensured accurate suspension height for nearly any air ride cab suspension.

The compact and durable design offers a low air flow rate, engineered to conserve air, lower compression run time, and increase suspension stability. Each kit comes with an integral, normally open dump valve featuring ceramic seal technology for high durability, even in the most extreme conditions. These design features make the 600 series the industry-best height control valve for usage on heavy duty applications.
