The K209333 Bendix BA-921 air brake compressor is the pump that makes the compressed air a heavy truck's brake system runs on. That same air supply also serves other systems on the truck, such as automated transmissions and emissions controls.
Compressors of this kind show wear in how they pump: when the piston rings or cylinder wall wear out, the unit pumps slowly or stops building air. A genuine Bendix part from Pro Gear and Transmission. Call us to confirm proper fit for your engine.
A factory handling fee of $25.00 per order is added at checkout.
