The Eaton Fuller Splitter Piston, part number 4304176 or HF4304176, is a direct-replacement internal transmission component for Eaton Fuller manual transmissions equipped with a splitter section. The splitter piston is the pneumatic actuator that drives range or splitter gear engagement when the driver toggles the splitter control on the shift knob. Using the correct OEM piston keeps air circuit sealing and actuating force within factory specification, which is critical for clean, positive splitter shifts. This is a genuine Eaton Fuller part, sold individually, available through Pro Gear and Transmission. Not sure this is the right piston for your box? Give us a call and we can help confirm proper fit.
