KYB Excel-G Rear Strut for Eclipse

KYB Excel-G 341404 is a rear suspension strut for 2006-2012 Mitsubishi Eclipse models. It is built to restore original ride control, stability, steering response, and handling balance without changing the vehicle’s designed suspension behavior.

The Excel-G line is KYB’s OE-style replacement series, produced on KYB assembly lines with OE-quality components and calibrated damping. For Mitsubishi Eclipse rear strut replacement, 341404 is a direct-fit option focused on maintaining factory ride characteristics.

Detailed Description

KYB 341404 is engineered for the rear suspension on the Mitsubishi Eclipse from 2006 through 2012. It is designed as an Original Equipment for the Aftermarket replacement, using OE-style construction and calibration to return the vehicle to its intended ride control and handling feel. This makes it a practical choice for drivers replacing worn rear struts on a Mitsubishi Eclipse, especially when consistent damping and stable body control are priorities.

The Excel-G platform is built to support the suspension, brakes, and electronic safety systems by helping the vehicle operate as the manufacturer intended. This part cross-references Monroe Shocks & Struts (e.g., 71145) for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced stability during lane changes and cornering
• Uneven tire contact caused by worn damping
• Delayed steering response from tired suspension components
• Loss of original ride control on a Mitsubishi Eclipse rear suspension

Installation Notes and Tips

Fits 2006-2012 Mitsubishi Eclipse, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify all mounting points, suspension bushings, and related wear items before installation. KYB recommends using a KYB strut boot, part number SB101, to help protect the strut from dirt, debris, and road salt.

Quality Assurance

KYB is a major OE supplier to new vehicle manufacturers, and the Excel-G line is produced on the same KYB OE assembly lines using OE-quality components. The 341404 rear strut is calibrated to restore original designed performance for the Mitsubishi Eclipse.
