1.290 Valve Spring Locators

The Manley 1.290 Valve Spring Locators are precision internal engine components designed to position valve springs accurately during engine assembly and rebuild operations. These locators maintain critical spacing and concentricity between the valve spring and its seating surface, directly affecting valve train durability and engine performance. Supplied as a set of 16 units, they are essential for consistent and verified locating during high-performance and stock engine builds.

Each locator measures 1.290 inches in outer diameter with a 0.505-inch inner diameter, sized to fit a 0.685-inch spring ID. The 0.035-inch thickness provides the precise control needed to prevent spring binding or misalignment under load. Constructed from hardened steel with a black oxide finish, these components resist corrosion and wear during repeated assembly cycles.

Professional engine builders, machine shops, and serious enthusiasts performing valve train service or engine rebuilds rely on valve spring locators to eliminate guesswork during assembly. Incorrect spring seating contributes to premature wear, valve float at high RPM, and potential catastrophic failure. Manley's reputation in high-performance engine components makes this locator a trusted choice for those seeking reliability and performance.
