Product Details

KYB Strut-Plus SR4129 is part of the KYB Strut-Plus line, a product family focused on restoring original ride height and suspension behavior with a complete strut-and-spring assembly. KYB draws on its OE supplier background to match the damping characteristics and spring rate to the vehicle application, helping maintain the handling balance expected from the factory setup. This part cross-references Monroe Shocks & Struts (e.g., 172186, 182186) for the same application.

Compatible With 2003-2005 Honda Civic, front left, and 2002-2003 Acura EL, front left. Common search terms for this part include front left strut assembly for 2003-2005 Honda Civic, Honda Civic front left coil spring strut assembly, and 2002-2003 Acura EL front left suspension strut replacement.
