Rear Suspension Subframe / Crossmember Mitsubishi Lancer Evolution X

Firstly, Buy Mitsubishi Evo X rear suspension subframe 4100A056. Restore the rear suspension mounting structure of your Mitsubishi Lancer Evolution X with the Mitsubishi Lancer Evolution X rear suspension subframe / crossmember. This genuine Mitsubishi component, OEM part number 4100A056, is cataloged as the Rear Suspension Cross-member / Axle Beam Mount and is used on applicable 2008–2015 Mitsubishi Lancer Evolution X models.

The rear suspension crossmember is an important structural component of the Evo X rear suspension system. It provides mounting points for suspension components and helps connect the rear suspension assembly to the vehicle body. Mitsubishi’s factory service information specifically identifies the component as the rear suspension crossmember and provides dedicated removal and installation procedures for it.

For an Evo X undergoing suspension repair, accident repair, restoration, or chassis refurbishment, replacing a damaged or corroded crossmember with the correct OEM Mitsubishi component can help restore the original suspension mounting arrangement.

Mitsubishi Lancer Evolution X Rear Suspension Subframe / Crossmember

The Mitsubishi Lancer Evolution X rear suspension subframe / crossmember is identified by OEM part number 4100A056. Genuine Mitsubishi parts catalogs describe the component as “Cross-member, Rear Suspension”, while other OEM catalogs specify “Crossmember, Rear Suspension; Axle Beam Mount.”

The component is listed for Mitsubishi Lancer Evolution X models including Evolution GSR, Evolution MR, Evolution MR Touring, and Evolution SE applications within the 2008–2015 model range.

Because the rear crossmember is part of the suspension mounting structure, it is significantly more important than a cosmetic body component. Damage, corrosion, or distortion can affect the condition and positioning of the surrounding suspension hardware. When rebuilding an Evo X, the correct OEM crossmember provides the appropriate factory-designed mounting structure for the applicable suspension components.

Genuine OEM Mitsubishi Construction

This rear suspension crossmember is a genuine Mitsubishi OEM component rather than a universal aftermarket replacement. The OEM catalog identifies Mitsubishi as the manufacturer and 4100A056 as the manufacturer part number.

Using an original Mitsubishi component can be particularly valuable for Evo X restoration projects where maintaining factory specifications and original suspension geometry is important. The crossmember is designed as part of the Evo X suspension architecture rather than being adapted from a different vehicle.

Designed for the Evo X Rear Suspension

The Evo X uses a sophisticated independent rear suspension system with multiple control links, arms, stabilizer components, hubs, knuckles, and differential-related hardware. The rear suspension crossmember forms part of the mounting structure for this assembly.

Mitsubishi’s factory service manual includes a specific Rear Suspension Crossmember removal and installation procedure. The procedure involves removal of associated control links, lower arms, stabilizer bar, knuckles, driveshaft, and rear differential assembly before removing the crossmember.

This illustrates the importance of treating the component as part of the complete rear suspension assembly rather than simply as a basic bolt-on bracket.

Why Replace the Evo X Rear Suspension Crossmember?

A rear suspension crossmember may require replacement following collision damage, corrosion, incorrect previous repairs, or extensive vehicle restoration. A damaged crossmember can also make it difficult to properly restore the surrounding suspension assembly.

Firstly, 4100A056 is the genuine Mitsubishi OEM identification for the applicable rear suspension crossmember.

Secondly, the component is specifically cataloged for Evolution X applications, including 2008–2015 Evo X models in Mitsubishi OEM parts listings.

Thirdly, using the correct OEM crossmember provides the original mounting structure for the rear suspension system, making it suitable for professional repair and restoration projects.

Evo X Suspension Restoration

When restoring a Mitsubishi Evolution X, suspension components should be inspected as a complete system. The rear crossmember works together with the rear control arms, lateral links, trailing arms, stabilizer bar, knuckles, differential assembly, and associated mounting hardware.

Mitsubishi’s factory service documentation specifically outlines the components that need to be removed when servicing the rear suspension crossmember, including the control links, lower arms, stabilizer bar, knuckles, driveshaft, and rear differential assembly.

Replacing the crossmember may therefore be appropriate during a larger suspension rebuild where several components are being refreshed simultaneously.

A replacement can also be useful for vehicles that have spent considerable time in areas where road salt, moisture, and corrosion can affect underbody components. Before installation, the surrounding chassis mounting areas should be inspected for damage or corrosion.

Related Rear Suspension Components

The Evo X rear suspension contains several additional OEM components that may be required during a complete rebuild. Mitsubishi parts catalogs separately list suspension crossmember stays, bolts, control arms, knuckles, stabilizer components, and other related hardware. For example, 4100A058 and 4100A063 are cataloged as rear suspension crossmember stays for applicable Evo X models.

This means the crossmember should be matched with the correct supporting brackets, fasteners, suspension components, and vehicle configuration during installation.

If you are searching for a Mitsubishi Evo X rear suspension subframe for sale, 4100A056 is the OEM Mitsubishi part number to identify for the applicable rear suspension crossmember.

This component is particularly useful for Evo X owners restoring a damaged vehicle, replacing a worn or corroded rear suspension structure, or returning a modified car to an OEM-style configuration.

When ordering, always confirm the OEM part number against the vehicle’s VIN or chassis number.

Professional Installation Recommended

Because the rear suspension crossmember is a structural suspension mounting component, installation should be performed by a qualified automotive technician.

The factory service procedure involves removing multiple suspension and drivetrain components before the crossmember can be removed. Mitsubishi also specifies that certain fasteners require particular tightening procedures and that some components should be fully tightened with the vehicle at curb-weight condition.

After installation, the vehicle should be inspected carefully and a professional suspension alignment should be performed where appropriate.
