KYB Strut Mount Kit for Front Suspension

KYB SM5423 is a front suspension strut mount kit built for OE-style replacement on select Toyota and Lexus applications. It addresses the vibration, noise, and steering feel issues that can develop when original mounts and bearing plates wear out.

For drivers searching for a front strut mount for a 2004-2010 Toyota Sienna, 2001-2007 Toyota Highlander, or 2002-2006 Toyota Camry, this KYB Mount Components part is engineered to restore suspension function with application-specific fitment.

Key Features

  • Application-specific OE quality replacement strut mount kit
  • Superior rubber helps reduce noise, vibration, and harshness
  • Mount bearings support smoother steering response and front-end alignment retention
  • Front bearing plates serve as steering pivots and support vehicle weight
  • Matched-grade studs and nuts for proper component matching

Product Details

KYB Mount Components focuses on replacing worn vibration insulators and mount hardware with parts designed around the original suspension layout. The SM5423 helps isolate road impact before it reaches the cabin, while the bearing plate supports steering movement and alignment stability. This makes it a practical choice for restoring front suspension performance on vehicles such as the Toyota Sienna, Toyota Highlander, and Lexus RX-series and ES-series applications listed below.

This part cross-references Monroe Shocks & Struts 904989 for the same application.

What It Helps Fix

  • Front suspension noise from worn strut mounts
  • Harsh vibration transmitted into the cabin
  • Steering bind or rough steering feel at the top mount
  • Front-end alignment drift related to worn bearing plates
  • Impact noise over bumps caused by hardened insulators

Installation Notes

Verify the vehicle’s suspension configuration before ordering, especially on Lexus RX and ES applications with exclusions for air or adjustable suspension. Confirm front-position fitment and compare the original mount and bearing layout to the replacement part before installation. Professional strut service procedures are recommended because the strut assembly must be handled under spring tension.

Quality Assurance

KYB is known for OE-quality suspension replacement components, and the Mount Components line is built to match the needs of each specific application. SM5423 is designed to support consistent front suspension operation on the listed Toyota and Lexus models.
