Mitsubishi Evo 7-9 AYC Diff pump

Mitsubishi Lancer Evolution 7–9 AYC Differential Pump

Replacement AYC (Active Yaw Control) differential pump to suit Mitsubishi Lancer Evolution 7, 8 and 9 models.

The AYC pump is a critical component of the Evo’s AWD system, responsible for controlling hydraulic pressure to the rear differential and distributing torque between the rear wheels.

A failing pump can cause AYC warning lights, loss of rear torque transfer, and reduced handling performance.

Common symptoms of failure:

- AYC warning light on dash

- Loss of rear differential torque control

- Fault codes related to AYC pressure
