Genuine Mitsubishi Rear Floor Crossmember For Mitsubishi Lancer Evolution 4 5 6 7 8 9 (RS / MR / GSR With RS Diff Conversion – Non-AYC) MR392699

Firstly, Buy Evo 4-9 RS Rear Floor Crossmember MR392699 online for non-AYC and RS differential conversions. Restore the rear floor and differential mounting structure of your Mitsubishi Lancer Evolution with the Genuine Mitsubishi Rear Floor Crossmember MR392699. This OEM Mitsubishi component is designed for Evolution models equipped with the RS-style mechanical rear differential, including RS and MR applications and GSR models converted from AYC to an RS rear differential.

Part number MR392699 is listed as the rear floor crossmember with PNC 65124E. Mitsubishi parts references show this component across the Evo 5–9 range, while specific listings also identify it for Evo 4–9 RS applications.

This crossmember is an important part of the rear floor structure. It provides the correct factory mounting structure around the rear differential and rear suspension area. For restoration projects, AYC-to-RS conversions, corrosion repairs, or replacement of a damaged original component, using the correct RS-spec crossmember is essential.

Genuine Mitsubishi MR392699 Rear Floor Crossmember

The MR392699 Rear Floor Crossmember is a genuine Mitsubishi OEM structural component developed for the rear floor of compatible Lancer Evolution models. It is specifically associated with the RS rear differential configuration.

The RS and AYC rear differential systems use different rear-floor crossmember arrangements. Ross Sport, for example, identifies MR392699 as the RS crossmember and distinguishes it from MB835841, which is used for the GSR/AYC configuration.

Firstly, this makes MR392699 an important component when converting an Evo from an AYC rear differential to an RS mechanical differential.

Secondly, the factory-style mounting locations help maintain the correct relationship between the rear differential and surrounding chassis structure.

Thirdly, it is an excellent choice for restoring an older Evo where the original rear crossmember has suffered corrosion, damage, or previous modifications.

Evo 4–9 RS and Non-AYC Applications

The MR392699 crossmember is intended for Mitsubishi Lancer Evolution models using the RS-style rear differential setup. It is listed across multiple Evolution generations, including Evo 5, 6, 7, 8, and 9.

It can also be relevant to an Evo GSR that has been converted from its original AYC differential to a mechanical RS differential. The important factor is therefore the rear differential configuration, not simply the Evo generation.

This distinction is important when ordering. A GSR equipped with its original AYC differential should not automatically be assumed to use the same crossmember as an RS-converted vehicle.

Key Features and Benefits

• Genuine Mitsubishi OEM rear floor crossmember
• OEM part number: MR392699
• PNC: 65124E
• Rear floor structural component
• Designed for RS rear differential applications
• Suitable for Evo 5–9 applications
• Applicable to RS and compatible MR configurations
• Suitable for GSR models converted to an RS mechanical differential
• Ideal for AYC-to-RS conversion projects
• Useful for Evo chassis restoration and repair
• Factory-style mounting and construction
• Suitable for replacing damaged or corroded original components

The component is manufactured as part of the vehicle’s rear floor structure. Because it is a structural part, inspect the surrounding chassis and mounting areas carefully during installation. If the vehicle has corrosion or accident damage, the adjacent floor and chassis sections should also be checked.

Compatible Mitsubishi Evolution Models

The MR392699 rear floor crossmember is associated with several Mitsubishi Evolution generations:

• Mitsubishi Lancer Evolution IV
• Mitsubishi Lancer Evolution V
• Mitsubishi Lancer Evolution VI
• Mitsubishi Lancer Evolution VII
• Mitsubishi Lancer Evolution VIII
• Mitsubishi Lancer Evolution IX
• RS models
• Compatible MR applications
• GSR models with RS differential conversion
• Non-AYC rear differential setups

Parts catalog data specifically lists MR392699 against CP9A and CT9A Evolution applications, including Evo 5 RS and Evo 6 RS, while other OEM references list it for later CT9A models.

Always verify the differential configuration and vehicle chassis before ordering.

Ideal for AYC-to-RS Differential Conversions

One of the most important applications for MR392699 is an Evo that is being converted from AYC to an RS-style mechanical rear differential.

The rear crossmember is part of the structure that supports the rear drivetrain assembly. When converting an Evo from AYC to RS, using the appropriate RS crossmember helps ensure the rear floor is configured for the correct differential setup.

This makes MR392699 particularly useful for serious Evo builds, motorsport projects, restoration vehicles, and owners returning an Evo to an RS-style drivetrain configuration.

OEM Replacement for Evo Restoration

Older Mitsubishi Evolution models can develop corrosion around the rear floor, chassis legs, and suspension mounting areas. Ross Sport notes that corrosion can become a significant issue in the rear chassis area as these vehicles age.

Replacing a compromised crossmember with a genuine Mitsubishi component can therefore form part of a larger structural restoration.

It is also useful when repairing an Evo that has previously been modified. If an aftermarket or fabricated component has been installed and the vehicle is being returned to an OEM-style configuration, MR392699 provides the correct factory reference point for the RS rear floor arrangement.

If you are restoring an Evo 4–9 or completing an AYC-to-RS differential conversion, choosing the correct rear floor crossmember is an important part of the build.

The MR392699 is specifically associated with the RS rear differential configuration, making it different from the crossmember used with the factory AYC/GSR setup. Ross Sport identifies MB835841 as the GSR crossmember and MR392699 as the RS version.

Before ordering, confirm your Evo generation, chassis, rear differential type, and existing crossmember. This is especially important for GSR vehicles that have been converted to RS drivetrain components.
