Product Details

KYB SM5953 is engineered as a suspension shock absorber mount for the rear upper position on 2016-2019 Mercedes-Benz C300 models. KYB’s Mount Components line focuses on replacement mount and bearing plate parts built for specific applications, helping address the noise, harshness, and vibration that can develop when original mounts harden with age. This part cross-references Mercedes-Benz OE number 2053230220 for the same application. Compatible With 2018-2019 Mercedes-Benz C300, rear upper, and 2016-2017 Mercedes-Benz C300, rear upper (exc. air suspension).

Common Issues This Part Can Address

• Clunking or knocking from the rear upper suspension area
• Excess vibration felt through the chassis
• Increased cabin noise from deteriorated mount insulators
• Reduced suspension isolation over bumps and rough pavement
• Wear-related looseness at the rear upper strut mounting point

Installation Notes and Tips

Verify rear upper fitment before installation, especially on 2016-2017 Mercedes-Benz C300 models without air suspension. Inspect the surrounding strut hardware, spring seat, and bearing surfaces for wear before reassembly. For best results, replace related suspension wear items as needed and follow factory service procedures for torque and alignment checks after installation.

Quality Assurance

KYB is known for OE-style replacement suspension components, and the SM5953 is built to match the listed application requirements for the Mercedes-Benz C300 rear upper mount position.
