Valve Spring Seat Cups - 1.560

The CROWER Valve Spring Seat Cups 1.560 in OD (MPN 68940-16) is a precision valve spring locator designed for internal engine assembly and high-performance engine building. These steel seat cups function as positioning guides that maintain proper valve spring concentricity during assembly and operation, ensuring consistent spring load delivery and extended component life.

Each set includes 16 cups with a 0.060-inch thickness, 1.560-inch outside diameter, 0.562-inch inside diameter, and 0.740-inch spring seating ID. These dimensions are engineered to work with specific valve spring assemblies and cylinder head configurations where precise spring seat height is critical. Proper spring seat installation prevents binding, ensures uniform load distribution across the spring coils, and protects against premature fatigue failure. The steel construction provides the rigidity needed to maintain dimensional stability under sustained engine operation and thermal cycling.

This product is essential for engine builders, performance mechanics, and shops performing complete valve train rebuilds or high-RPM engine modifications. CROWER is recognized in the engine component industry for manufacturing precision valve train parts that meet tight tolerances. The 16-cup quantity provides sufficient stock for multi-cylinder engine work or replacement sets. These locator cups are suitable for naturally aspirated and forced-induction applications where controlled spring rate and seating consistency are non-negotiable.

Verify fitment with your specific cylinder head design and valve spring assembly before ordering, as seat cup dimensions are application-specific. Proper installation requires careful alignment to avoid spring cocking or uneven load paths that could compromise engine reliability.
