Product Details

KYB Excel-G is built on KYB OE assembly lines using OE-quality components and calibration focused on restoring original suspension behavior rather than changing it. Part number 340091 is a front right suspension strut for the Nissan 370Z and related INFINITI applications, making it a practical choice when replacing a worn strut on a performance coupe or sports sedan. This part cross-references Nissan E61101EA0C for the same application.

What It Helps Address

• Excessive bouncing or reduced damping control
• Loose steering feel during lane changes and cornering
• Uneven tire contact caused by worn suspension control
• Body movement that affects braking stability and ride consistency
• Alignment issues related to flex in a worn strut body
