Comp Cams Spring Seat Cup .060 .640 I.D./1.680 O.D. 4700-16

Valve spring seat cups are critical components that locate and support your valve springs with precision—improper seating leads to spring bind, valve float, and catastrophic engine failure. The Comp Cams Spring Seat Cup (.060" thickness, .640" I.D./1.680" O.D.) delivers the exact locating geometry needed for reliable high-RPM performance. This set of 16 ensures you have matched pairs for all eight cylinders, maintaining symmetrical spring preload across your entire valvetrain.

Whether you're building a solid-lifter race engine or upgrading an existing cylinder head, these steel seat cups provide the precision fit that separates a stable, durable engine from one prone to valve train issues. Comp Cams' manufacturing tolerances ensure consistency across the entire set, eliminating variables that compromise performance.
