Spring Seat Cup .060 .640 I.D. 1.730 O.D.

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 who require exact positioning of valve springs during assembly. This set of 16 steel cups ensures consistent spring seating geometry, which is critical 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 valve springs with a 1.730-inch outer diameter and a 0.640-inch inner diameter. 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 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. It is essential for those looking to enhance the performance and reliability of their valve spring assemblies.
