KYB SM5978 Suspension Strut Mount Kit - Front Right

Overview

KYB SM5978 is a suspension strut mount kit for the front right position on select Chevrolet Blazer applications. It replaces worn vibration insulators and bearing plate components that can transmit noise, harshness, and steering looseness into the cabin.

Key Features

• OE-quality replacement strut mount kit engineered for the application.
• Helps isolate road impact, vibration, and noise from the suspension.
• Front bearing plate supports steering movement and wheel alignment.
• Built for direct service on compatible Chevrolet Blazer models.
• KYB Mount Components line focuses on suspension mounting and support parts.

Detailed Description

KYB SM5978 is part of the Mount Components product line and is engineered as an OE-quality replacement for the suspension mount assembly. On compatible Chevrolet Blazer vehicles, the strut mount and bearing plate work together to cushion road inputs, reduce vibration transfer, and maintain proper steering response. The bearing plate also serves as a steering pivot and load-support point, making it an important service part when the original mount has hardened or worn out. This part cross-references Monroe Shocks & Struts (e.g., 84472040, 84563445) for the same application.

Common Issues Addressed

• Suspension noise from worn or hardened mount insulators.
• Excess vibration felt through the chassis or steering.
• Reduced steering precision caused by worn bearing support.
• Alignment concerns related to degraded strut mount components.
