FLOTEK Valve Spring Locators

FLOTEK valve spring locators (or cups) serve as hardened, CNC-machined steel seats designed to protect aluminum cylinder heads from spring galling while accurately centering the valve spring over the guide. They prevent the springs from "walking" or moving during high-RPM, high-lift operations, reducing valvetrain damage and ensuring consistent, stable valve spring pressure. These components have a black oxide coating for durability, are compatible with specific valve guides and spring pocket sizes for secure fitment and are crucial for maintaining stability in high-performance engines.
