Pump ACD AYC EVO 7-9 GSR MR Stage 1

A restored combined ACD/AYC pump for the Lancer Evolution VII, VIII and IX in GSR and MR specification, feeding both the Active Center Differential and the Active Yaw Control circuits. The pump is completely disassembled and ultrasonically cleaned, worn parts are replaced with genuine components, and the rebuilt unit is calibrated for pressure, flow and solenoid response on the bench, then run under simulated drivetrain load as a final check. This is a Stage 1 build: restored for improved performance and noticeably faster pressure build-up. 12-month warranty, shipped worldwide.
