KYB Excel-G is the brand’s OE replacement line for drivers who want the suspension to perform as the vehicle manufacturer originally engineered it. Part number 335057 is made on KYB OE assembly lines using OE-quality components and is classified as an Original Equipment for the Aftermarket replacement. This part cross-references Monroe Shocks & Struts (e.g., 72431) for the same application.

Common Problems This Strut Addresses

• Excessive bounce or poor damping at the front right corner
• Reduced steering response during lane changes and cornering
• Uneven tire contact caused by worn suspension control
• Noise or instability from a fatigued front strut assembly
• Alignment drift from flex in a worn strut body or bracket

Installation Notes and Tips

Install according to the manufacturer’s instructions for the Mitsubishi Eclipse front right position. Replace suspension strut and coil spring assembly as specified for the application, and verify the correct build date for the 2010 Eclipse from 1/2010. Inspect related suspension components, and consider a KYB strut boot, part number SB101, to help protect the new strut from dirt, debris, and road salt.

Quality Assurance

KYB is a major OE supplier to vehicle manufacturers, and the Excel-G line is produced on the same KYB OE assembly lines with OE-quality components. Part number 335057 is engineered to restore designed suspension performance for the Mitsubishi Eclipse front right application.
