Overview

The Mitsubishi OEM AYC/ACD Differential Pump is a genuine OEM hydraulic unit. It carries a factory warranty and is manufactured to OEM fit and quality standards.
Show original supplier description
The Mitsubishi OEM AYC/ACD Differential Pump, part number 3520A071, is a genuine OEM hydraulic unit designed specifically for the 2008-2015 Mitsubishi Evo X. This pump is a common failure point on the Evo X due to its placement behind the rear passenger tire, making this a crucial replacement part for maintaining the vehicle's Active Yaw Control (AYC) and Active Center Differential (ACD) systems. This hydraulic unit offers OEM fit and quality, ensuring seamless integration with your Evo X's existing systems. It comes with a manufacturer standard warranty, providing assurance of its reliability and performance. The package includes one hydraulic differential pump, ready for installation. Customer reviews indicate that this pump is often used in conjunction with aftermarket relocation kits to mitigate future failure risks caused by its original mounting position. While the part itself is a direct OEM swap, some users opt for additional modifications like a trunk relocation kit for enhanced durability.
