Spring Locators - .570 ID 1.655in

COMP Cams Spring Locators with 0.570 inch ID and 1.655 inch outer diameter are precision valve spring positioning components engineered for engine builders, machine shops, and serious automotive enthusiasts performing cylinder head work. These hardened steel locators maintain critical spring concentricity during valve train assembly, ensuring consistent preload and preventing spring binding that can cause catastrophic valve failure in high-RPM or high-boost applications.

The 0.060 inch thickness and 0.630 inch spring ID accommodate standard domestic valve spring dimensions found in small-block and big-block engine platforms. The 1.655 inch OD provides stable seating on cylinder head valve seats without interference with rocker arms or other head components. Steel construction delivers the hardness necessary to withstand repeated assembly cycles and the lateral forces imposed during high-lift cam operation. Set of 16 ensures complete coverage for engines with 16 valves (V8 applications) or allows mixed-spring setups common in performance builds with dual-rate springs.

Buyers tackling ported heads, valve spring upgrades, or complete engine rebuilds depend on locators to maintain valve geometry within factory or custom specifications. Improper spring seating introduces parasitic losses, creates uneven wear on rocker tips and pushrods, and increases risk of coil bind in high-lift scenarios. COMP Cams' engineering background in racing engine components translates directly to precision tolerances and material selection that withstand professional machine shop demands and weekend warrior builds alike.
