Valve Spring Locators - 1.540in

The Valve Spring Locators – 1.540in from ISKY CAMS are precision internal engine components designed to maintain proper valve spring positioning during high-performance engine assembly and operation. These locators are essential for builders, machine shops, and motorsports enthusiasts working with performance cylinder heads where valve spring concentricity and load distribution directly impact engine longevity and reliability. The 1.540-inch outer diameter specification makes these locators suitable for applications requiring exact spring seat alignment on commonly sized valve springs.

Each set includes 16 chromoly locators, a durable material choice that provides excellent dimensional stability and resists deformation under sustained spring pressure. At 0.045 inches thick with a 0.570-inch inner diameter and 0.740-inch spring ID bore, these locators precisely position valve springs while preventing lateral movement and misalignment that can accelerate wear on valve guides and seats. The inside-mount design allows for seamless integration into cylinder head assemblies, ensuring springs seat at the correct angle and maintain uniform contact with retainers across the entire engine's RPM range.

These valve spring locators benefit engine builders, performance shops, and enthusiasts assembling or rebuilding heads for street, strip, or track applications. They are particularly valuable when upgrading to high-lift cam profiles or increasing valve spring rates, where precision locating becomes critical to prevent coil bind, spring surge, and premature failure. Installation requires careful attention to cleanliness and proper seating on the valve spring seat; the full set of 16 covers all intake and exhaust positions on a complete V8 or equivalent multi-cylinder engine build.
