The COMP Cams Spring Seat Cup .060 .640 I.D. 1.730 O.D. (Part Number 4702-16) is a precision valve spring locator designed for engine builders and performance enthusiasts requiring exact positioning of valve springs during assembly. This set of 16 steel cups ensures consistent spring seating geometry across multiple valve configurations, a critical requirement for maintaining valve train stability and preventing resonance-related failures during high-RPM operation.
The .060-inch thickness provides a measured spring seat that accommodates the 1.650-inch spring O.D., while the 1.730-inch O.D. and 0.640-inch I.D. specifications allow proper interference fit on the valve stem and spring retainer assembly. COMP Cams engineered these dimensions to maintain tight tolerances across the entire spring stack, which directly translates to predictable valve lift profiles and reduced valve chatter—particularly important in high-lift cam applications where spring deflection can cause timing variance. The steel construction resists deformation under sustained load, preserving the locating geometry through thousands of engine cycles.
This product serves engine builders, performance machine shops, and serious enthusiasts who assemble or rebuild small-block and big-block V8 engines, particularly those running aggressive cam profiles or high-rev applications. Each cup in the 16-piece set is ready for installation, eliminating the need to source individual components and reducing assembly time. The specification match with COMP Cams valve spring lines ensures compatibility across their entire performance catalog.
Precision valve spring locators are standard in professional engine shops because improper seating leads to spring wobble, accelerated wear on retainers, and potential valve float at elevated RPM. COMP Cams' OEM-quality manufacturing backs this set of 16 cups, providing the dimensional consistency that separates a reliable build from one prone to valvetrain failures.
