KYB SM5978 Suspension Strut Mount Kit

The KYB SM5978 is a replacement suspension strut mount kit engineered to restore proper suspension function and ride quality. The strut mount serves as the critical connection point between the strut assembly and the vehicle chassis, absorbing road impacts and isolating noise and vibration from the cabin.

KYB strut mounts are built to meet or exceed original equipment specifications, using matched-grade components for a secure, precise fit. Over time, factory mounts degrade and harden, allowing increased noise, vibration, and harshness (NVH) to pass through into the vehicle — the SM5978 is designed to eliminate these symptoms and return suspension performance to like-new condition.

Key Features:

• Meets or exceeds OE performance and fitment specifications
• Superior rubber construction reduces noise, vibration, and harshness (NVH)
• Mount bearing promotes smoother steering response and helps retain front-end alignment
• Matched-grade hardware included for a complete, secure installation
• Cushions road impacts to reduce jarring transmitted into the vehicle cabin
• Sold as a single unit

KYB is a globally recognized OE supplier of suspension components for major automakers. The SM5978 strut mount kit is backed by KYB's one-year limited warranty on strut mount and non-damper suspension components.
