KYB SM5695 Suspension Shock Mounting Kit - Rear Upper

KYB SM5695 Rear Upper Strut Mount for Infiniti

KYB SM5695 is a suspension shock absorber mounting kit built for rear upper applications on select Infiniti FX models. It addresses the vibration, noise, and harshness that can develop when original vibration insulators wear out, while helping restore proper suspension feel.

For 2003-2008 Infiniti FX35 and FX45 rear upper service, this KYB Mount Components part is engineered as an OE-quality replacement with application-specific design.

Key Features

• OE-quality replacement strut mount for the intended application
• Superior rubber 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 proper component fitment
• Built to optimize suspension performance on the vehicle it was designed for

Product Details

KYB Mount Components focuses on replacement suspension hardware that restores the function of worn upper mounts and related support parts. The SM5695 is designed to cushion road impacts, reduce the jarring effect transmitted into the cabin, and help maintain consistent suspension operation. On vehicles such as the Infiniti FX35 and Infiniti FX45, a worn rear upper mount can contribute to clunks, vibration, and a less controlled ride. KYB SM5695 is a direct-fit service part for those rear upper applications.

This part cross-references Infiniti OE numbers 55323CG00A and 55323CG000 for the same application.

Installation Notes and Tips

Confirm rear upper placement before installation and compare the original mount to the new part for correct application matching. Inspect surrounding suspension components, including the strut assembly and related hardware, for wear before reassembly. Professional installation is recommended because suspension components affect ride quality, steering behavior, and alignment.
