Spring Seat Locators - 1.450x1.00x.570

COMP Cams Spring Seat Locators (1.450x1.00x.570) are precision-engineered valve spring components designed for OEM and performance engine builds requiring exact spring positioning during assembly. These locators establish proper spring seating geometry, a critical requirement for valve train stability and consistent performance across all RPM ranges. Supplied as a set of 16 units, they're manufactured from steel to withstand repeated assembly cycles and the mechanical demands of high-flow cylinder head work.

The 1.450-inch outside diameter seats against the cylinder head spring pocket, while the 0.570-inch inside diameter accommodates the valve stem and guides spring centering. The 0.060-inch thickness ensures proper shim stack height and pressure distribution across the spring seat interface. Correct locator specification is essential for maintaining valve lift accuracy, reducing unwanted spring harmonics, and preventing premature spring fatigue. These specifications work in conjunction with compatible valve springs and retainers to deliver predictable valve events throughout the engine's operating range.

Engine builders and machine shops rely on COMP Cams locators during cylinder head preparation, restoration, and performance upgrades. Whether restoring a classic engine to OEM specification or optimizing a modified head package, these locators ensure the valve spring assembly functions as designed. The set of 16 pieces covers a typical cylinder head (4 springs per cylinder on a 4-cylinder engine). Technicians should verify compatibility with their specific spring diameter and retainer design before ordering, as incorrect locator dimensions can compromise valve train geometry and engine reliability.
