The 1.69in Valve Spring Seat Cups from COMP CAMS are precision-engineered locators designed for high-performance engine builds and valve train modifications. These steel cups serve as critical positioning components in various cylinder heads, ensuring proper spring seating geometry during assembly and operation. Whether you're rebuilding a classic muscle car, upgrading a street rod, or preparing a competition engine, these seat cups maintain the exact installed height required for reliable valve control and longevity.

Each 1.69in Valve Spring Seat Cup features a 1.780 inch outer diameter with a 0.640 inch inner diameter bore, designed to accommodate the 1.690 inch spring outside diameter specification. The 0.060 inch thickness provides rigid support without adding unnecessary mass, and the steel construction ensures durability under the extreme thermal and mechanical cycling that valve springs endure. This set of 16 cups is ideal for mechanics and engine builders looking to install aftermarket valve spring kits or restore original equipment cylinder heads to factory specifications.

Proper spring seat cups are essential for any valvetrain modification, as they prevent spring migration and maintain consistent preload, which directly impacts cam timing accuracy and valve sealing integrity. These components are widely used in various engine applications, making them a versatile choice for both professional and amateur builders. With the right valve spring seat cups, you can ensure optimal performance and longevity of your engine's valve train.
