Mitsubishi OEM Input Shaft 5th Gear Synchro Evo X 2551A147

Firstly, Buy Mitsubishi OEM Input Shaft 5th Gear Synchro Evo X 2551A147 online. The Mitsubishi OEM Input Shaft 5th Gear Synchro Evo X 2551A147 is a genuine Mitsubishi factory replacement component designed for the 5-speed manual transmission found in the Mitsubishi Lancer Evolution X. This OEM 5th-speed synchronizer assembly is an important part of the transmission gear-selection system and is designed to work with the factory Evo X manual transmission components. Mitsubishi parts catalogs identify 2551A147 as the M/T 5th Speed Gear Synchronizer Ring Assembly, with diagram reference 22540A.

For Evo X owners rebuilding, refreshing, or repairing a 5-speed manual transmission, using the correct factory synchronizer component can help maintain the intended fit and compatibility of the original transmission design. This part is specifically associated with the 5-speed manual transmission and should not be confused with components used in the Evo X MR TC-SST transmission.

Mitsubishi OEM Input Shaft 5th Gear Synchro Evo X 2551A147

The Mitsubishi OEM Input Shaft 5th Gear Synchro Evo X 2551A147 is manufactured as a genuine Mitsubishi replacement part rather than an aftermarket reproduction. Parts specialists list it specifically for the 2008–2015 Mitsubishi Evo X, while Mitsubishi catalog data places the part within the 5-speed input-shaft gear assembly.

This makes it a useful choice for transmission rebuilds where the original fifth-gear synchronizer assembly is worn, damaged, or being replaced as part of a broader manual transmission overhaul.

Genuine Mitsubishi OEM Construction

One of the biggest advantages of choosing an OEM transmission component is the factory-specific design. The 2551A147 is made for the Evo X 5-speed manual transmission application rather than being a universal synchronizer component.

When rebuilding an Evo X transmission, correct component dimensions, engagement surfaces, and compatibility with the surrounding transmission hardware are important. Installing the correct Mitsubishi part helps the transmission builder maintain the original configuration.

5th-Speed Synchronizer Ring Assembly

The primary function of a manual transmission synchronizer is to help coordinate gear-speed matching during gear engagement. The fifth-speed synchronizer assembly works as part of the transmission’s 5th-gear engagement system.

Mitsubishi catalog information lists 2551A147 specifically as the M/T 5TH SPEED GEAR SYNCH RING ASSY. The same catalog identifies other associated fifth-gear components, including the 5th synchronizer hub and sleeve, showing that 2551A147 is one component within the complete fifth-gear synchronization system.

This distinction is important when ordering transmission parts. The synchro ring assembly is not the same component as the synchronizer hub, sleeve, or fifth gear itself.

Designed for the Evo X 5-Speed Manual Transmission

The 2551A147 is intended for the Mitsubishi Lancer Evolution X 5-speed manual transmission. Parts listings identify the application as 2008–2015 Evolution X, while Mitsubishi catalog information confirms its use within the CZ4A 5-speed manual transmission assembly.

This part is therefore appropriate for Evo X manual-transmission projects where the correct fifth-speed synchronizer assembly is required.

Important: The Evo X was available with different transmission configurations, including the MR’s TC-SST. This product is for the 5-speed manual transmission, not the MR TC-SST. Always verify your transmission configuration and VIN before ordering.

Why Replace the 5th Gear Synchro?

A worn synchronizer can contribute to difficult or less-consistent gear engagement. During a transmission rebuild, inspecting the synchronizer components is especially important because wear in one part of the gear-selection system can affect the overall operation of the transmission.

Replacing a worn fifth-speed synchronizer assembly can be appropriate when:

• Rebuilding an Evo X 5-speed manual transmission
• Repairing fifth-gear engagement issues
• Replacing worn transmission components
• Restoring an OEM transmission
• Refreshing a high-mileage manual gearbox
• Replacing damaged synchronizer components
• Building a spare or replacement Evo X transmission

A professional transmission inspection should determine whether the synchronizer ring, hub, sleeve, gear, bearings, or other related components also require replacement.

OEM Fit and Transmission Compatibility

The advantage of ordering Mitsubishi OEM 2551A147 is that the part is designed around the factory transmission application. Mitsubishi’s catalog places the component in the 5-speed input-shaft section of the manual transmission.

Parts specialists also describe the product as an OEM Mitsubishi fifth-gear synchronizer for the Evo X 5-speed transmission, with one listing specifying that the purchase includes one 3-piece gear assembly as pictured.

Because transmission configurations can vary by market and model year, it is still recommended to confirm the exact part number against the vehicle VIN before installation.

Firstly, Secondly, Thirdly — Why Choose Genuine Mitsubishi 2551A147?

Firstly, genuine Mitsubishi construction gives you a factory-designed component intended for the Evo X manual transmission application.

Secondly, the correct fifth-speed synchronizer is important when rebuilding the transmission and restoring the original gear-selection system.

Thirdly, buying the correct OEM part helps avoid the uncertainty that can come with universal or incorrectly specified aftermarket transmission components.

Installation Considerations

Installation of the Mitsubishi OEM Input Shaft 5th Gear Synchro Evo X 2551A147 requires transmission disassembly and should be performed by a qualified transmission specialist or experienced mechanic. The synchronizer works together with other fifth-gear transmission components, so the surrounding parts should be inspected during installation.

Before assembly, inspect the associated fifth-gear hub, sleeve, gear, bearings, shafts, and related transmission components for excessive wear or damage. If multiple components show wear, replacing only the synchronizer may not resolve an underlying transmission problem.

Proper transmission assembly procedures, clearances, lubrication, and inspection should follow the appropriate Mitsubishi service information.
