KYB SM5854 Suspension Shock Mounting Kit - Rear Upper

KYB SM5854 Rear Upper Strut Mount for Sentra

KYB SM5854 is a suspension shock absorber mounting kit built for the rear upper position on select Nissan Sentra models. It replaces worn vibration insulators and mount components that can transmit road noise, harshness, and unwanted movement into the cabin.

For 2013-2018 Nissan Sentra rear upper applications, this KYB Mount Components part is focused on restoring proper suspension feel and reducing the effects of aged mounting hardware. The KYB SM5854 is engineered as an OE-quality replacement for drivers who want predictable fitment and consistent suspension response.

Key Features

• OE-quality replacement strut mount for the rear upper position
• Superior rubber helps reduce noise, vibration, and harshness
• Mount bearing design supports smoother steering response where applicable
• Helps maintain front-end alignment and suspension stability
• Matched-grade studs and nuts for application-specific service

Product Details

KYB Mount Components are designed around the needs of each application, and the SM5854 follows that approach for Nissan Sentra rear upper service. As vibration insulators age and harden, they can create clunks, rattles, and a rougher ride; this mount helps restore the isolation the suspension was meant to provide. KYB strut mounts and bearing plates are known for their OE-style construction and application-specific design, making them a practical choice for suspension repair on the 2013-2018 Nissan Sentra.

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

What It Helps Address

• Rear suspension noise from worn mounting components
• Excess vibration transferred into the vehicle body
• Harsh ride quality caused by hardened insulators
• Steering or alignment concerns related to worn mount hardware
• Reduced suspension isolation on Nissan Sentra rear upper service

Installation Notes

Install the KYB SM5854 in the rear upper position only on the listed Nissan Sentra applications. Inspect surrounding suspension parts, fasteners, and bearing surfaces during service, and replace any worn components that could affect ride quality or alignment. Proper torque and alignment procedures should be followed after installation.

Quality Assurance

KYB builds Mount Components as OE-quality replacement parts for application-specific suspension service. The SM5854 reflects that approach with materials and design intended to restore factory-like function in the rear upper mount location.
