KYB SM5403 Suspension Strut Mount Kit - Front

KYB SM5403 Strut Mount Kit Overview

KYB SM5403 is a front suspension strut mount kit built for OE-style replacement on select Honda and Acura applications. It addresses the vibration, noise, and harshness that worn mount insulators can transmit into the cabin while helping restore steering feel and front-end control.

Key Features

• OE-quality replacement strut mount components designed for each application
• Superior rubber helps reduce noise, vibration, and harshness from the front suspension
• Mount bearings support smoother steering response and help retain front-end alignment
• Front bearing plates act as steering pivots and support vehicle weight
• Matched-grade studs and nuts for application-specific service

Detailed Product Description

The KYB Mount Components line focuses on restoring suspension function with replacement parts engineered around the original application. The SM5403 strut mount kit is designed for front suspension use on Honda Civic, Honda CR-V, Honda Element, Acura RSX, and Acura EL models listed in the fitment data. By replacing hardened or worn mount insulators, this kit helps reduce clunks, road harshness, and steering vibration that can develop as the original parts age.

This part cross-references Monroe Shocks & Struts 906919 for the same application. If you are searching for a KYB SM5403 strut mount kit for 2001-2005 Honda Civic front suspension service or a front strut mount replacement for 2002-2006 Honda CR-V, this part is built for that type of repair.

What It Helps Address

• Front-end noise from worn strut mounts
• Steering vibration caused by deteriorated mount bearings
• Harsh impact transfer from road bumps into the cabin
• Alignment instability related to worn front bearing plates
• Reduced steering smoothness during suspension movement

Installation Notes and Tips

Install on the front suspension only and verify vehicle fitment by year, make, model, and position before service. Because the bearing plate is part of the steering pivot, inspect related front suspension components during replacement and confirm alignment after installation. For Honda Civic, Honda CR-V, Honda Element, Acura RSX, and Acura EL applications, compare the original mount style and bearing layout before removing the strut assembly.

Quality Assurance

KYB positions this Mount Components product line as an OE-quality replacement solution for suspension service. The SM5403 is built to match the application-specific requirements of the listed vehicles and to support consistent front suspension operation.
