KYB SM5664 Suspension Strut Mount - Front

KYB SM5664 Strut Mount for Subaru Front Suspension

KYB SM5664 is a front suspension strut mount built for Subaru applications that need a direct replacement for worn vibration insulators and mount bearings. It helps restore quieter operation, steadier steering response, and proper front-end alignment behavior on vehicles such as the Subaru WRX, WRX STI, Forester, Crosstrek, Impreza, Legacy, Outback, Tribeca, and XV Crosstrek.

Key Features

• OE-quality replacement strut mount for front suspension service
• Superior rubber helps reduce noise, vibration, and harshness from the road
• Mount bearings support smoother steering input and alignment retention
• Matched-grade studs and nuts for application-specific fitment
• Built to replace hardened or deteriorated vibration insulators

Product Details

KYB Mount Components are engineered as application-specific replacement parts for suspension service. The SM5664 strut mount cushions road impacts, reduces the jarring effect transmitted into the cabin, and supports the steering pivot function at the front of the vehicle. On Subaru platforms, that matters for maintaining consistent steering feel and front-end geometry. This part cross-references Monroe Shocks & Struts 908926 for the same application.

Compatible With front suspension service on Subaru WRX, Subaru WRX STI, Subaru Forester, Subaru Crosstrek, Subaru Impreza, Subaru Legacy, Subaru Outback, Subaru Tribeca, Subaru B9 Tribeca, and Subaru XV Crosstrek applications listed below. The KYB SM5664 is a practical replacement when the original mount has become noisy, stiff, or worn from age and mileage.

What It Helps Address

• Clunking or knocking from the front strut area
• Excess vibration transferred into the cabin
• Harsh ride feel caused by hardened mount rubber
• Steering looseness related to worn mount bearings
• Front-end alignment drift after mount wear
