Detailed Description

KYB 3430089 is an Excel-G rear shock absorber engineered for 2014-2015 Mitsubishi Mirage and 2017-2024 Mitsubishi Mirage rear applications. The Excel-G product line is KYB’s Original Equipment for the Aftermarket offering, meaning it is calibrated to return the vehicle to its original designed ride characteristics rather than alter them. This makes 3430089 a practical replacement when the goal is to recover factory-style control in a Mitsubishi Mirage.

This part cross-references Mitsubishi OE numbers 4162A219 and 4162A396 for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Loose or unsettled rear ride control
• Reduced stability during lane changes
• Longer stopping feel caused by worn rear damping
• Uneven handling response from tired rear shocks

Installation Notes and Tips

Verify rear fitment by model year before ordering: Fits 2014-2015 Mitsubishi Mirage, rear, and Fits 2017-2024 Mitsubishi Mirage, rear. Confirm mount style and dimensions against the original shock before installation. Inspect related suspension components, including bushings and mounts, so the replacement shock can perform as intended.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is produced on the same OE assembly lines using OE-quality components. That manufacturing approach supports consistent fit and factory-style damping for Mitsubishi Mirage rear shock replacement. Part number 3430089 is an OE-style suspension shock absorber for the listed applications.
