Mitsubishi OEM Transfer Case O-Ring for Evo X (3200A144)

Firstly, Buy Evo X OEM Transfer Case O-Ring 3200A144 online for 2008–2015 models. The Mitsubishi OEM Transfer Case O-Ring for Evo X (3200A144) is a genuine Mitsubishi factory sealing component designed for the Mitsubishi Lancer Evolution X transfer-case assembly. This OEM O-ring is used at the transfer-case input shaft area to provide a proper seal between the transfer case and gearbox, helping maintain fluid retention and prevent unwanted leakage within the AWD drivetrain.

Mitsubishi identifies part number 3200A144 as the Transfer Case Input Shaft Seal, while Evo-specific parts suppliers describe it as the transfer-to-gearbox O-ring. The component is listed under Mitsubishi PNC 30289 and is supplied individually.

For Evo X owners rebuilding a transfer case, replacing drivetrain seals, servicing the gearbox-to-transfer-case connection, or restoring an AWD system with genuine Mitsubishi hardware, the 3200A144 provides the correct OEM part-number reference for this sealing location.

Evo X OEM Transfer Case O-Ring 3200A144

The transfer case and transmission form a critical part of the Evolution X AWD drivetrain. Their mating area requires the correct sealing components to help retain the specified fluids and prevent contamination or leakage.

The 3200A144 is specifically associated with the transfer-case input shaft sealing location. Evo-specific OEM listings identify it as the O-ring used between the transfer case and gearbox, making it particularly relevant when the transfer case is removed or disassembled.

Firstly, using the correct Mitsubishi O-ring provides the factory-specified replacement for the applicable sealing location.

Secondly, replacing an old sealing ring during transfer-case service can help avoid reusing a component that may have become worn or compromised.

Thirdly, using the exact OEM part number makes it easier to identify the correct seal rather than relying on an incorrectly sized generic O-ring.

Genuine Mitsubishi OEM Construction

The 3200A144 is a genuine Mitsubishi OEM component rather than a universal aftermarket O-ring. Mitsubishi’s official parts catalog lists it as the Transfer Case Input Shaft Seal for the Evolution GSR 2.0L application.

Nengun’s Mitsubishi OEM catalog also identifies 3200A144 as “O-RING, T/F CASE” and lists it for the Lancer Evolution X CZ4A with the 4B11T engine.

Transfer Case to Gearbox Sealing

The connection between the transmission and transfer case is an important area of the Evo X AWD drivetrain. When these components are separated during servicing, the condition of the associated seals and O-rings should be inspected carefully.

A worn, damaged, flattened, or improperly seated sealing ring can contribute to fluid leakage. Replacing the O-ring during transfer-case service can therefore be an important part of completing a drivetrain repair correctly.

The 3200A144 is specifically identified by Evo X parts suppliers as the transfer-to-gearbox O-ring, making it a useful OEM replacement whenever the applicable sealing area is being serviced.

When Should the 3200A144 Be Replaced?

The O-ring may be replaced during transfer-case removal, transfer-case rebuilding, transmission servicing, or when addressing a leak around the transfer-case input area.

Common situations include:

• Evo X transfer-case removal
• Transfer-case rebuilding
• Gearbox-to-transfer-case servicing
• AWD drivetrain repairs
• Transfer-case resealing
• Replacement of a damaged O-ring
• Restoration of an OEM drivetrain
• Preventive replacement during major drivetrain service
• Repair of fluid leakage around the transfer-case mating area

Because an O-ring is a sealing component, it is generally good practice to inspect it whenever the associated components are separated rather than automatically reusing an old seal.

Evo X Transfer Case Rebuild Applications

During a transfer-case rebuild, several seals and O-rings may be involved. The 3200A144 is one of the specific OEM sealing components associated with the transfer case.

Mitsubishi parts information separately identifies other transfer-case sealing components, including 3200A145, which is listed as a transfer-case output shaft seal. This means the 3200A144 should not be confused with the transfer-case output seal.

This distinction is important when ordering individual replacement seals. Searching by the exact Mitsubishi part number helps ensure that the correct sealing component is selected for the intended location.

Evo X Fitment

The Mitsubishi OEM 3200A144 is documented for the Mitsubishi Lancer Evolution X (CZ4A) with the 4B11T engine. Nengun’s OEM catalog lists the part across multiple Evolution X production applications, including 2008, 2009, 2014, 2015, and related production records.

Some aftermarket suppliers specifically list the part for 2008–2015 Evolution X models.

Because OEM applications can vary by drivetrain configuration and market, it is recommended to confirm the part number against the vehicle VIN and transfer-case configuration before ordering.

Important Manual and SST Consideration

The Evo X was offered with different drivetrain configurations, and transfer-case components can vary. One Evo X parts supplier specifically notes that certain transfer-case seal applications are not confirmed for MR models because OEM transfer-case part numbers differ between configurations.

For this reason, buyers should verify 3200A144 against the specific vehicle and transfer case before ordering, particularly when working with an MR/SST vehicle or a drivetrain that has been swapped or modified.

Why Use a Genuine Mitsubishi O-Ring?

Using a genuine Mitsubishi sealing component offers several advantages when completing an OEM-focused repair. The part is identified by the Mitsubishi catalog number 3200A144, allowing the installer to match the replacement directly to the factory parts reference.

A genuine OEM replacement is especially useful for:

• Factory restoration
• Transfer-case rebuilds
• AWD drivetrain maintenance
• Professional transmission work
• Evo X performance builds
• Long-term drivetrain servicing
• Replacement of damaged or reused seals

Rather than selecting a generic O-ring based only on appearance, using the correct Mitsubishi part number provides a more reliable way to identify the intended component.
