KYB SM5734 Shock Mount - Rear Upper

KYB SM5734 Rear Upper Strut Mount

KYB SM5734 is a rear upper suspension shock absorber mount built for select Nissan 370Z and Infiniti rear suspension applications. It replaces worn vibration insulators and bearing components that can add noise, harshness, and steering or alignment concerns.

Part of KYB Mount Components, this strut mount is engineered as an OE-quality replacement for the specific application. It is a direct-fit service part for rear upper mounting points on the listed vehicles, including the Nissan 370Z and Infiniti G37, G35, G25, Q60, and Q40.

Key Features

• OE-quality replacement strut mount for the specified rear upper application
• Superior rubber construction helps reduce noise, vibration, and harshness
• Mount bearing design supports smoother steering response and front-end alignment retention where applicable
• Matched-grade studs and nuts for application-specific fitment
• Built to replace hardened or deteriorated vibration insulators

Product Details

KYB Mount Components are designed to restore suspension feel by addressing the wear points that develop in the upper mount assembly. On vehicles such as the 2009-2019 Nissan 370Z rear upper mount application and the 2008-2013 Infiniti G37 rear upper mount application, a worn mount can transmit road impact, cabin noise, and vibration into the chassis. KYB SM5734 is engineered to replace that worn interface with a component matched to the original application requirements. This part number, SM5734, is also listed for 2007-2008 Infiniti G35 rear upper, 2011-2012 Infiniti G25 rear upper, 2014-2015 Infiniti Q60 rear upper, and 2015 Infiniti Q40 rear upper applications.

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

What It Helps Address

• Rear suspension noise caused by worn upper mount insulators
• Excess vibration transferred into the cabin from deteriorated mount rubber
• Harsh impact feel over bumps and rough pavement
• Steering or alignment concerns related to worn bearing plates where equipped
• Loose or degraded upper mount support in the rear suspension

Installation Notes

Install SM5734 only on the listed rear upper applications for the confirmed vehicle fitment. Inspect the surrounding suspension hardware, spring seat area, and related wear components before reassembly. Because strut mount service affects suspension geometry, a professional alignment check is recommended after installation.

Quality Assurance

KYB positions Mount Components as OE-quality replacement parts designed for each application, with a focus on restoring original suspension performance characteristics. The brand’s strut mounts and bearing plates are known for application-specific fit and consistent component quality.
