KYB SM5482 Suspension Shock Mounting Kit - Rear Upper

KYB SM5482 Rear Upper Strut Mount

KYB SM5482 is a suspension shock absorber mounting kit for rear upper applications on select Infiniti and Nissan models. It replaces worn strut mount components that can transmit vibration, noise, and harshness into the cabin while helping restore more precise suspension response.

Built under KYB’s Mount Components line, this part focuses on OE-style fit and function for the specific application. It is a practical choice for drivers servicing a 2003-2007 Infiniti G35, 2003-2009 Nissan 350Z, or 2006-2010 Infiniti M35/M45 rear upper mount.

Key Features

• OE-quality replacement strut mount for the specified rear upper position
• Superior rubber helps reduce noise, vibration, and harshness
• Mount bearings support smoother steering response and front-end alignment retention where applicable
• Matched-grade studs and nuts for application-specific service
• Engineered to restore suspension performance on worn mount assemblies

Product Details

KYB Mount Components are designed around the needs of each vehicle application, and SM5482 follows that approach for rear upper suspension service. By replacing hardened or deteriorated mount insulators, this component helps reduce the jarring effect caused by road impacts and supports more controlled suspension movement. For drivers searching for a KYB SM5482 strut mount for Infiniti G35 or Nissan 350Z rear upper service, this part addresses the common symptoms of aged mount hardware and rubber isolation.

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

What It Helps Fix

• Clunking or knocking from worn rear upper mount components
• Excess cabin vibration from hardened vibration insulators
• Harsh ride feel over bumps and uneven pavement
• Reduced steering smoothness caused by worn mount bearings
• Alignment instability related to deteriorated suspension support points

Installation Notes and Tips

Install SM5482 only in the listed rear upper positions for the confirmed vehicle applications. Inspect the surrounding suspension hardware, spring seats, and bearing surfaces before assembly, and replace any visibly worn related components during service. Proper torque and alignment checks after installation help ensure correct suspension operation.
