Spring Seat Locators - ..060x.780x.878x.1253

COMP Cams Spring Seat Locators (0.060×0.780×0.878×1.253) are precision valve spring positioning components engineered for engine builders and performance machinists working on high-revving applications. These hardened steel locators maintain consistent spring geometry and preload during assembly, critical for reliable valve train operation and preventing spring surge under sustained RPM.

The set of 16 locators features exact inside diameter (0.780 in ID), outer diameter (1.253 in OD), and spring-seating dimensions (0.878 in spring ID) that ensure proper fit between the valve spring seat and the spring coil itself. The 0.120-inch thickness provides adequate material for consistent clamping without excess mass. Proper locator installation prevents spring slippage and the micro-deflections that lead to premature fatigue failure in competition or high-output engines.

Engine builders, small-block and big-block rebuilders, and performance machine shops rely on COMP Cams locators as standard components during head assembly. Whether building a street performance engine, vintage race application, or professional rebuild, these locators ensure the valve spring stack maintains alignment and preload specification throughout engine operation. The 16-piece quantity accommodates a complete V8 engine build with spares for quality control verification.

COMP Cams is recognized in the engine performance industry for precision manufacturing standards. Spring seat locators are foundational components often overlooked in casual builds but critical to engine reliability and longevity, particularly in applications where sustained high RPM or boost is a factor.
