1.250 Spring Cups

The 1.250 Spring Cups by Manley are precision valve spring locators designed for serious engine builders and high-performance machine shops. These external spring cups are essential components in cylinder head assembly, ensuring proper seating and support for valve springs during installation and operation.

Manufactured from durable steel with a professional black oxide finish, the 1.250 Spring Cups are engineered to accommodate 1.250-inch spring outer diameters. The thickness of 0.062 inches provides optimal rigidity while maintaining precise geometry for repeatable spring preload and seat pressure. The black oxide coating offers corrosion resistance and reduces light reflection, making these cups ideal for environments where durability and consistency matter.

Professional engine builders, machine shops, and experienced enthusiasts rely on these spring cups when working with aftermarket cylinder heads or custom valve train configurations. The set includes 16 units, providing complete coverage for V8 engines and allowing for spares or future projects without downtime.
