KYB SM5519 Coil Spring Insulator - Front Upper

KYB SM5519 Coil Spring Insulator

KYB SM5519 is a front upper coil spring insulator for the 2004-2005 Ford Explorer. It replaces hardened spring seat material that can transmit vibration into the suspension and cabin, helping restore quieter operation and more consistent spring isolation.

Built under KYB’s Mount Components line, this spring insulator is made as an OE-style replacement for the specific application. It is a practical choice when servicing the front suspension on a Ford Explorer and looking to address noise at the spring seat.

Key Features

• OE-quality replacement spring insulator for the front upper suspension position
• Helps reduce squeaks, rattles, and vibration noise from worn insulators
• Built to match or exceed original equipment design and quality
• Part number SM5519 for easy identification and ordering
• Compatible with 2004-2005 Ford Explorer front upper applications

Product Details

KYB’s Mount Components line focuses on suspension mounting parts that support proper isolation between the spring and surrounding components. This SM5519 coil spring insulator is engineered to replace aged or hardened factory material that can no longer absorb road vibration effectively. For Ford Explorer owners, that means a direct-fit suspension service part for the front upper location on 2004-2005 models.

This part cross-references Monroe Shocks & Struts 906924 for the same application. If you are searching for a Ford Explorer front upper coil spring insulator, KYB SM5519 is the catalog reference to use.

Common Problems It Can Help Address

• Suspension squeaks from the spring seat area
• Rattling or clunking noises over bumps
• Excess vibration transferred through worn insulators
• Degraded spring isolation caused by hardened rubber material
• Noise concerns during front suspension repair on a Ford Explorer

Installation Notes

Install the insulator in the front upper spring position on the specified Ford Explorer applications. Inspect the surrounding spring seat, strut mount area, and related suspension components for wear before reassembly. Proper alignment of the spring and insulator is important for quiet operation and consistent suspension performance.

Quality Assurance

KYB positions its Mount Components line as OE-quality replacement suspension hardware, with design and material standards intended to match original equipment expectations for the application. SM5519 is built to support reliable spring isolation on the 2004-2005 Ford Explorer.
