Detailed Description

KYB 3430099 is an Excel-G rear shock absorber for Honda Civic applications, including 2016-2025 Civic rear and 2026 Civic rear left. The Excel-G product line is engineered to restore the vehicle’s original suspension behavior using OE-style construction and calibration, making it a direct choice for drivers who want factory-level ride control rather than a changed suspension feel. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Reduced rear-end stability during braking
• Loose or delayed response in lane changes
• Uneven or inconsistent handling feel
• Worn shock performance on Honda Civic rear suspension

Installation Notes and Tips

Verify the mount style and dimensions before installation: lower mount E2 (14.2x36) and upper mount S1 (10MM). Confirm rear position and model year against the vehicle’s existing shock absorber, especially on 2026 Honda Civic rear left applications. Inspect related suspension components for wear before replacing the shock.

Quality Assurance

KYB is a major OE shock and strut supplier, and the Excel-G line is produced on the same assembly lines used for KYB original equipment products. The 3430099 is built to OE-quality standards and calibrated for original performance restoration.
