KYB SM5806 Suspension Strut Mount - Front

KYB SM5806 Front Strut Mount for Subaru

KYB SM5806 is a front suspension strut mount built for Subaru Legacy and Subaru Outback applications with sport suspension coverage in select years. It replaces worn vibration insulators and bearing components that can add noise, harshness, and steering play to the front end.

As part of KYB Mount Components, this strut mount focuses on OE-style fit and suspension function for the front of the vehicle. It is a direct replacement for the original mount design used on the listed Subaru Legacy and Outback applications.

Key Features

• OE-quality replacement strut mount for front suspension service
• Superior rubber helps reduce noise, vibration, and harshness
• Mount bearing supports smoother steering response and front-end alignment retention
• Optimizes suspension performance with application-specific design
• Matched-grade studs and nuts

Product Details

The KYB Mount Components line is engineered for suspension service where the upper strut mount and bearing play a critical role in ride quality and steering feel. On Subaru Legacy and Subaru Outback front suspension systems, a worn mount can transmit road impact into the cabin and affect steering precision. KYB SM5806 is designed to restore the function of the original mount location with a replacement component that addresses vibration isolation and steering pivot support.

This part cross-references Subaru 20320AG000 and 20320AG01A for the same application. KYB SM5806 is a practical choice when servicing the front strut assembly on 2006-2007 Subaru Legacy and 2007 Subaru Outback, as well as 2008-2009 Subaru Legacy and 2008-2009 Subaru Outback with sport suspension.

What It Helps Fix

• Front-end clunking or knocking from a worn strut mount
• Excess vibration and road noise entering the cabin
• Harsh ride feel caused by hardened mount insulators
• Steering looseness or reduced steering smoothness
• Front alignment concerns related to worn mount bearings

Installation Notes

Install the strut mount during front suspension service when the strut assembly is removed. Verify the vehicle application, position, and suspension configuration before installation. For 2008-2009 Subaru Legacy and 2008-2009 Subaru Outback, this part applies to front sport suspension applications; for 2006-2007 Subaru Legacy and 2007 Subaru Outback, it applies to the front position as listed.

Because the mount and bearing affect steering pivot and wheel alignment, a professional alignment check is recommended after suspension work is completed.

Quality Assurance

KYB designs Mount Components as OE-quality replacement parts for the listed applications, with attention to ride control, steering support, and noise isolation. The SM5806 follows KYB’s application-specific approach for front suspension service on Subaru Legacy and Subaru Outback models.
