Product Details

KYB Excel-G is the brand’s OE-style replacement line for drivers who want factory-like suspension behavior rather than a changed ride feel. The Excel-G line is calibrated to restore the vehicle’s designed performance, making it a practical choice for a Nissan Sentra rear shock replacement when original control, braking stability, and lane-change response are priorities. Part number 3440012 is built to match the application requirements for 2014-2019 Nissan Sentra rear suspension service.

This part cross-references Monroe Shocks & Struts (e.g., 5525, 5532) for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced stability during braking or lane changes
• Loose or unsettled rear suspension feel
• Uneven tire contact caused by worn damping
• Loss of factory-like ride control on a Nissan Sentra
