FTI Valve Spring Locators - (.563" guide)
These hardened and fully machined valve spring locators provide a steel alloy seat that will not only protect the head and shim, but also precisely locates the valve spring, centered on the valve stem. The inside diameter shoulder locates on the valve guide boss with tighter tolerances than our competitors for more precise spring control. The outside diameter fits most small diameter hydraulic roller dual springs. Check cylinder head spring pocket diameter for fitment.

- Protects the head & shim while properly locating & holding the valve springs in place
