Spring Seat Locators - 1.300x.800x.570

Spring Seat Locators - 1.300x.800x.570 from COMP CAMS are precision engineered components designed for serious engine builders, performance mechanics, and hot rod enthusiasts who demand reliability during high-RPM operation. These valve spring locators serve a critical function: they precisely position the coil spring on the cylinder head, preventing lateral movement and ensuring consistent spring load delivery under extreme combustion pressures. Whether you're rebuilding a street performance engine, preparing a competition platform, or restoring a classic muscle car, proper spring seating is non-negotiable for longevity and consistent performance.

Each locator measures 1.300 inches outer diameter with a 0.800-inch spring inner diameter and 0.570-inch inner diameter bore, manufactured from hardened steel and precision ground to exact tolerances. The 0.060-inch thickness ensures adequate bearing surface while minimizing dead weight—critical in lightweight valve train assemblies. This set includes 16 locators, enough to outfit an eight-cylinder engine with matched pairs for each valve location. Steel construction resists deformation under sustained spring pressure, maintaining dimensional accuracy across thousands of heat cycles and preventing the spring migration that causes premature wear on the valve seat and retainer.

These locators are essential for any cylinder head featuring a spring-over-damper or dual-spring configuration where precise seating prevents harmonics-induced failures. They're compatible with most small-block and big-block applications using standard coil-over-valve spring designs. Installation involves placing the locator in the spring pocket before assembling the valve train—a straightforward but critical step that separates quality machine work from cutting corners. Mechanics and engine builders who prioritize consistency and reliability choose COMP CAMS spring seat locators to ensure every valve operates under optimal load characteristics.
