Traditional cab suspension systems must typically compromise ride comfort and stability. LORD MR Cab Suspensions, however, offer a solution to manage these conflicting goals. Our solutions integrate the air spring, MR Damper, controls, sensors and leveling valves in a single unit. The air spring provides a soft suspension for low-frequency vibrations, while the MR Damper is turned on only when needed to provide stability and shock protection. The leveling valves help keep the cab level during operation to provide optimal suspension performance during most driving conditions.
