COMP Cams 4641-100 ID Valve Spring Seat Locators - 1.540" OD, .520" ID, .060" Thick

Each locator measures 1.540" O.D., .520" I.D., and .060" thick, providing precise spring positioning and reliable head protection under high-performance conditions.

Key Features:

• 1.540" Outer Diameter — properly seats the 26547 series dual valve springs
• .520" Inner Diameter — designed for use with .520" valve guide diameter
• .060" Thickness — precision ground for consistent installed height
• Hardened steel alloy construction — withstands extreme spring pressures and high RPM without deforming
• Protects cylinder head and shim surfaces from spring wear and galling
• Locates and holds the spring in place for consistent valvetrain geometry

Standard OEM-style shims are not built to handle the extreme seat pressures generated by high-lift performance valve springs. COMP Cams ID spring seat locators replace inadequate factory shims with a purpose-built, hardened steel solution that maintains proper spring alignment and protects the cylinder head surface over the long term. The 4641-100 is the recommended spring seat for use with COMP Cams part number 26547 valve springs.
