Detailed Description

KYB 348066 is engineered as an OE replacement shock absorber for the rear suspension on the 2012-2013 Honda Civic. It is designed to restore the vehicle’s original ride control, stability, stopping behavior, and handling response by matching the suspension’s factory calibration. The Excel-G design uses OE-quality components and a twin-tube, nitrogen gas-charged construction to support consistent damping performance in everyday driving.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are replacing a worn rear shock on a Honda Civic, 348066 is built to return suspension behavior closer to factory specifications without changing the vehicle’s intended ride characteristics.

What It Helps Address

• Excessive rear-end bounce after bumps
• Loose or unstable handling in turns
• Reduced braking stability caused by worn damping
• Poor lane-change response
• Uneven tire contact from weakened suspension control

Installation Notes and Tips

Fits 2012-2013 Honda Civic, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount style, compressed length, extended length, and stroke length before installation to confirm proper suspension travel and fitment. Because this is a rear shock absorber application, inspect related suspension components for wear during service.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is built on KYB OE assembly lines using OE-quality components. The design focus is restoring original suspension performance for the Honda Civic while maintaining correct alignment support and consistent damping characteristics.
