Maintain the stopping power and safety of your diesel rig with the BD Diesel Replacement Air Cylinder. This component is the primary actuator for BD Diesel air-powered exhaust brake systems, responsible for the precise opening and closing of the butterfly valve within the exhaust stream. When a cylinder develops leaks or internal wear, it can lead to sluggish response or a complete loss of engine braking performance.

Constructed to withstand the harsh thermal cycles and road debris typical of under-vehicle mounting, this cylinder ensures your exhaust brake provides the necessary backpressure for controlled descents. It is a direct-fit replacement part designed to bolt into existing BD Diesel brake assemblies, restoring factory-level actuation speed and holding force.
