Detailed Description

KYB Excel-G is KYB’s OEA-classified aftermarket line, meaning it is engineered to restore the vehicle’s original suspension behavior rather than alter it. This rear strut uses the same manufacturing approach and quality component standards found in KYB original equipment production, making it a practical choice for maintaining factory-style ride control on Infiniti Q50, Q70, Q70L, M35h, M37, and M56 rear suspension applications. The 3410100 strut measures 16.1 inches compressed, 20.22 inches extended, and provides 4.12 inches of stroke for the listed fitments.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive rear-end bounce or oscillation
• Reduced stability during braking and lane changes
• Loose or unsettled rear suspension feel
• Uneven handling response compared with factory behavior
• Worn rear strut performance on higher-mileage Infiniti sedans
