2009-2015 Mitsubishi Lancer Evolution X JDM 4B11 Transfer Case T-Case MR SST

About this unit

Key Specifications & Features

The Evolution X transfer case differs significantly from the older Evo 8/9 units, featuring a more robust housing to handle the torque of the 4B11 engine.

• Active Center Differential (ACD): The transfer case houses the ACD, which uses an electronically controlled hydraulic clutch to manage the front-to-rear torque split.

• Compatibility: While the 4B11T engine block is standard across all Evo X models, the transfer case must match your transmission type (Manual vs. SST) due to different mounting points and spline counts.

• JDM Benefits: Sourcing a JDM (Japanese Domestic Market) unit is a popular choice for North American owners because Japanese imports often have lower mileage and have not been exposed to the heavy road salt that causes corrosion in “rust belt” regions.

What is included

You receive exactly what is pictured. Engines are supplied as a long block assembly with the components visible in the photos. Accessories such as the alternator, starter, intake manifold or sensors are included only where you can see them on the unit, so check the photographs before ordering and ask us if anything is unclear.

Before you order

• Confirm the engine code against your own vehicle, not just the model year.
• Japanese market units can differ from the US version in intake, loom and sensors.
• Replace the timing components, water pump and seals while the unit is out. It is cheap insurance on an engine this age.
• Keep your original accessories until the swap is finished and running.
