KYB SM5524 Coil Spring Seat Insulator

The KYB SM5524 Spring Seat Insulator is an OE-quality replacement component engineered to restore proper suspension performance and eliminate the vibration and noise associated with worn or hardened factory insulators. Over time, original spring seat insulators degrade and lose their ability to isolate road noise and harshness, allowing unwanted vibration to transfer directly into the cabin.

Key Features:

• Eliminates suspension noise and vibration caused by old, hardened insulators
• Engineered to OE specifications for precise fit and function
• Restores original ride quality and suspension performance
• Application-specific design ensures correct seating geometry and load distribution
• Manufactured by KYB, a globally recognized OE supplier to major vehicle manufacturers

KYB designs and manufactures its aftermarket suspension accessories using the same materials, standards, and engineering processes as their original equipment components. The SM5524 spring seat insulator is part of KYB's complete line of shock and strut accessories, which includes mounting hardware, jounce bumpers, bellows, strut mounts, and coil springs — making it easy to complete a full suspension service with matched components.
