Product Details

KYB SM5945 is engineered for the rear upper mount location on 2016-2021 Honda Civic models.

This part number, SM5945, is a direct reference for the listed Civic fitment.

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

Common Issues It Can Address

• Excess vibration entering the cabin
• Harsh ride caused by worn mount insulators

Installation Notes

Inspect the surrounding suspension components, bearing surfaces, and fasteners before installation, and replace any worn parts found during service. Proper alignment checks are recommended after suspension work.
