Pump ACD AYC EVO 10 Stage 2
A restored combined ACD/AYC pump for the Lancer Evolution X, driving both the Active Center Differential and the Active Yaw Control circuits. Every unit is torn down, ultrasonically cleaned and rebuilt with genuine replacement components, then bench-calibrated for pressure, flow and solenoid response and load-tested before dispatch. This is a Stage 2 build: the factory electric motor is swapped for a more reliable unit — worth having, since motor wear is usually a symptom of a pump that has been fighting to build pressure. Bench-tested, covered by a 12-month warranty and shipped worldwide.
