KYB SM5985 Rear Upper Strut Mount

The KYB SM5985 is a rear upper strut mount engineered to restore proper suspension function and ride quality. Strut mounts are a critical link between the strut assembly and the vehicle chassis, and they endure significant stress — the insulator is pushed and pulled thousands of times per mile, causing rubber to harden and degrade over time. Replacing worn mounts with a quality unit like the KYB SM5985 helps eliminate clunking, noise, and vibration that worn mounts transmit into the cabin.

Key Features:

• OE-Quality or Better: Designed to meet or exceed original equipment specifications for a direct, confidence-inspiring replacement
• Noise & Vibration Reduction: Superior rubber insulator absorbs road impacts and isolates NVH (noise, vibration, and harshness) from the chassis
• Smooth Steering Response: High-quality mount bearings support smoother steering feel and help maintain proper front-end alignment
• Secure Chassis Connection: Provides a solid, properly aligned mounting point for the strut assembly, supporting consistent handling and tire wear
• 1-Year KYB Warranty: Backed by KYB's limited warranty covering defects in materials and workmanship

For best results, KYB recommends replacing strut mounts any time new struts are installed. The KYB SM5985 is built to the same standards as KYB's full suspension lineup, ensuring reliable performance mile after mile.
