KYB SM5645 Shock Mount - Rear Upper

KYB SM5645 Rear Upper Strut Mount

KYB SM5645 is a rear upper suspension shock absorber mount built for OE-style replacement on select Audi and Volkswagen applications. It addresses the noise, vibration, and harshness that worn vibration insulators can transmit into the cabin while helping restore suspension feel.

Compatible with 2005-2009 Audi A3, Audi A3 Quattro, Volkswagen Jetta, and 2008 Volkswagen R32 rear upper applications, this KYB Mount Components part is engineered for direct-fit service on the listed vehicles.

Key Features

• OE-quality replacement strut mount for the specified application
• Superior rubber helps reduce noise, vibration, and harshness
• Mount bearings support smoother steering response and front-end alignment retention
• Matched-grade studs and nuts for consistent component quality
• Built to cushion road impacts and reduce jarring transfer through the suspension

Product Details

KYB Mount Components focuses on replacement suspension hardware that matches the original application requirements. The SM5645 strut mount is designed to replace hardened or worn rear upper mount components that can create clunks, vibration, and a less controlled ride. On vehicles such as the Audi A3, Audi A3 Quattro, Volkswagen Jetta, and Volkswagen R32, the mount helps restore the isolation and support expected from the suspension system.

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

What It Helps Fix

• Suspension noise from worn upper mount insulators
• Excess vibration transferred into the cabin
