KYB SM5770 Suspension Shock Mounting Kit - Rear Upper

KYB SM5770 Strut Mount for Focus

KYB SM5770 is a suspension shock absorber mounting kit built for rear upper applications on select Ford Focus models. It addresses the noise, vibration, and harshness that worn vibration insulators can transmit into the cabin while helping restore proper suspension feel.

Compatible With 2008-2011 Ford Focus, rear upper. This KYB Mount Components part is engineered as an OE-quality replacement for the original mounting point used in the rear suspension.

Key Features

• OE-quality replacement strut mount for the specified application
• Superior rubber helps reduce noise, vibration, and harshness
• Mount bearings support smoother steering response and front-end alignment retention where applicable
• Matched-grade studs and nuts for proper fitment
• Built to optimize suspension performance on the vehicle platform

Product Details

KYB Mount Components are developed to replace hardened or worn suspension insulators that can cause clunks, rattles, and excess road feel. The SM5770 is designed for the rear upper mounting position on 2008-2011 Ford Focus models, helping the suspension isolate road impacts more effectively and maintain consistent ride quality. KYB SM5770 is a direct-fit service part for drivers addressing mount wear on the Ford Focus rear upper suspension location.

This part cross-references Ford 3S4Z18A161AA for the same application.

Common Problems This Part Can Address

• Noise from worn or hardened suspension mounts
• Excess vibration transferred into the body
• Harshness over bumps and rough pavement
• Loose or degraded rear upper mount feel
• Suspension noise caused by aging vibration insulators

Installation Notes

Verify the vehicle year, make, model, and rear upper position before installation. Inspect surrounding suspension components for wear, including the strut assembly and related hardware, so the new mount is installed into a serviceable system. Follow factory service procedures and alignment checks after suspension work when required.

Quality Assurance

KYB is known for OE-style suspension replacement components, and the SM5770 is built to the same application-specific standards used across the Mount Components line. The design focuses on restoring proper isolation and suspension function for the listed Ford Focus fitment.
