KYB Coil Spring Insulator P/N:SM5413

Help quiet suspension squeaks and rattles with the KYB coil spring insulator SM5413, a front upper spring seat insulator that cushions the coil spring against the suspension seat. It installs as a direct-fit replacement for many vehicles, among them the 1995-2023 Toyota Tacoma, 2003-2023 Toyota 4Runner and 2004-2012 Chevrolet Colorado — see the Buyer's Guide tab for the full list.

KYB spring seats and insulators are designed to address the vibration and noise caused by old, hardened insulators, offering an application-specific replacement that helps optimize suspension performance.

• Reduces noise: helps cut squeaks, rattles and vibration noises transmitted through the spring seat.
• Application-engineered: a quality replacement insulator designed for the specific application.
• OE-matched build: built with design and quality intended to match or exceed the original equipment insulator.
• Front upper fit: seats between the coil spring and the front upper suspension mount.

If a worn or hardened original insulator is the source of ride harshness or noise, this replaces it.
