Product Details

The KYB Strut-Plus line is built for drivers who need a direct suspension replacement that addresses both damping and ride height in one assembly. For the Honda Civic, SR4630 is engineered around the vehicle’s original suspension geometry so the front left corner can be restored with a matched strut and spring package. As an OE supplier, KYB applies original-equipment knowledge to help maintain the Civic’s handling feel, stability, and steering pivot function. Part number SR4630 is a practical choice when replacing a worn front left strut on a 2006-2011 Honda Civic.

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

Common Problems This Assembly Can Address

• Front-end bounce or reduced damping control
• Sagging ride height on the front left corner
• Noisy or worn strut assembly replacement needs
• Uneven handling response during braking or cornering
• Restoration of factory-style suspension geometry on a Honda Civic

Installation Notes and Tips

Install SR4630 on the front left only and verify the vehicle is a 2006-2011 Honda Civic before ordering. Because this is a complete strut and spring assembly, it reduces the need to transfer the spring from the old unit. After installation, inspect alignment settings and confirm ride height and steering wheel center are correct. Always follow factory service procedures for suspension fasteners and torque specifications.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to restore handling and control with OE-style fit and function. The SR4630 uses a KYB restoring strut and a high-carbon steel coil spring developed to help return the vehicle to OE ride-height targets.
