KYB SM5850 Shock Mount - Rear Upper

KYB SM5850 Rear Upper Strut Mount

KYB SM5850 is a rear upper suspension shock absorber mount built for OE-style replacement on select Hyundai and Kia vehicles. It helps restore quieter operation by replacing hardened vibration insulators that can transmit road noise and harshness into the cabin.

Compatible With 2010-2020 Hyundai and Kia applications, including Sonata, Optima, Cadenza, Azera, Sportage, and Tucson rear upper positions.

Key Features

• OE-quality replacement strut mount for application-specific fitment
• Superior rubber construction helps reduce noise, vibration, and harshness
• Mount bearings support smoother steering response and front-end alignment retention
• Front bearing plate design serves as a steering pivot and supports vehicle weight where applicable
• Matched-grade studs and nuts for proper component matching

Product Details

The KYB Mount Components line focuses on restoring suspension function with replacement parts engineered for the vehicle application. SM5850 is designed to address worn rear upper mount issues by cushioning road impacts and reducing the jarring effect that old mounts can transfer through the chassis. For drivers servicing a Hyundai Sonata, Kia Optima, or Kia Sportage, this mount supports more controlled suspension movement and a quieter ride.

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

Common Problems It Can Help Address

• Clunking or knocking from the rear suspension mount area
• Excess cabin vibration from hardened mount material
• Harsh ride feel over bumps and uneven pavement
• Steering or alignment concerns related to worn bearing components
• Reduced suspension isolation from deteriorated upper mount insulators

Installation Notes

Install SM5850 in the rear upper position only on the listed applications. Verify the mount location, inspect surrounding suspension components for wear, and confirm alignment after replacement if the vehicle shows signs of uneven tire wear or steering pull. Always match the part to the exact year, make, model, and position before installation.

Quality Assurance

KYB is known for OE-style suspension replacement components, and the SM5850 is built to meet application-specific requirements for fit and function. The KYB SM5850 is intended to restore mount performance on compatible Hyundai and Kia rear upper applications while maintaining the suspension characteristics expected from a direct replacement part.
