• OE-Quality Construction: Built to meet or exceed original equipment specifications for a direct, application-specific fit
• Superior Rubber Compound: High-grade rubber insulator reduces noise, vibration, and harshness for a quieter, more comfortable ride
• Bearing Plate Included: Integrated front bearing plate acts as the steering pivot and supports vehicle weight, maintaining proper steering response and wheel alignment

• Industry-Trusted Brand: KYB is a globally recognized OE supplier with a long-standing reputation for suspension quality and reliability

Strut mounts are a critical yet often overlooked component of the suspension system. Replacing a worn strut mount at the same time as the strut is a recommended best practice—saving on future labor costs and ensuring the new strut performs as intended. The KYB SM5478 strut mount is an integral part of a complete, professional-quality strut service.
