KYB SM5666 Suspension Shock Absorber Mount - Rear Upper

KYB SM5666 Rear Upper Strut Mount

KYB SM5666 is a rear upper suspension shock absorber mount built for vehicles that need a direct OE-style replacement for worn vibration insulators. It helps restore quieter operation, steadier suspension response, and more precise steering feel on applications such as Audi A4, A5, Q5, S4, SQ5, and Porsche Macan.

KYB Mount Components are engineered around application-specific fitment, with rubber and bearing materials selected to reduce road harshness and support suspension movement. For drivers dealing with clunks, vibration, or alignment-related steering issues, this rear upper mount is a practical replacement part.

Key Features

• OE-quality replacement strut mount for rear upper suspension locations
• Superior rubber helps reduce noise, vibration, and harshness
• Mount bearing design supports smoother steering response and alignment retention
• Matched-grade studs and nuts for application-specific service
• Built to replace hardened vibration insulators that can transmit road impact into the cabin

Product Details

KYB SM5666 is part of the KYB Mount Components line, which focuses on suspension mounting hardware that matches original equipment requirements by application. This rear upper mount is designed to cushion road impacts, reduce vibration transfer, and support the bearing function needed for stable suspension and steering performance. On vehicles such as the Audi A4 Quattro, Audi Q5, Audi A5 Quattro, and Porsche Macan, a worn rear upper mount can contribute to noise, harshness, and inconsistent ride quality. This part number, SM5666, addresses those symptoms with a direct replacement approach.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Clunking or knocking from the rear suspension over bumps
• Excess vibration or harshness entering the cabin
• Steering feel that becomes less precise as mount bearings wear
• Front-end or suspension alignment concerns related to worn bearing support
• Noise caused by hardened or deteriorated vibration insulators
