COMP Cams 4860-100 I.D. Spring Locator - 1.655" OD, .570" ID, .060" Thick

The COMP Cams I.D. Spring Locator provides a superior solution for high-performance racing engines that demand maximum spring pressure and high RPM operation. This hardened steel alloy seat protects both the cylinder head and shim while precisely locating and securing the valve spring in place.

Key Features:

• Hardened steel alloy construction withstands extreme spring pressures and high RPM conditions
• Inside diameter locator design with shoulder on the interior eliminates extensive head machining
• Dual-function design protects cylinder head surface and provides positive spring location
• 1.655" outer diameter, .570" inner diameter, .060" thickness
• Superior alternative to standard shims that fail under racing conditions

Unlike older cup-style locators that require significant head machining to accommodate an external retaining shoulder, this I.D. locator features the locating shoulder on the inside diameter. This innovative design minimizes machine work while delivering the same performance benefits of traditional spring cups. Perfect for engine builders who need reliable valve train stability without compromising cylinder head integrity.
