KYB Suspension SM5777 Strut Mount and Bearing Kit

The KYB Suspension SM5777 Strut Mount and Bearing is an OE-quality replacement component designed to restore proper suspension function and eliminate common problems associated with worn strut mounts. This critical suspension component serves dual purposes: cushioning road impacts while providing a steering pivot point for front suspension systems.

Key Features:

• Eliminates vibration and noise caused by deteriorated rubber insulators
• OE-quality construction designed for precise application-specific fit
• Integrated bearing plate serves as steering pivot and supports vehicle weight
• Restores proper wheel alignment and steering performance
• Reduces transmission of road shock and jarring into the cabin
• Direct replacement for worn or damaged factory strut mount assemblies

KYB strut mounts are engineered to match the original equipment specifications, ensuring proper suspension geometry and performance. The bearing plate component is critical for maintaining accurate steering response and wheel alignment angles. When strut mounts wear out, symptoms include clunking noises over bumps, poor steering returnability, and increased cabin vibration—all of which this replacement component addresses.
