The Speedmaster PCE470.1004 valve spring cups are precision-manufactured from hardened steel, designed to support and locate valve springs in high-performance engine applications. These cups measure 1.370" outer diameter, 0.760" inner diameter, and 0.040" thick, providing the durability and dimensional accuracy required for reliable valve train operation.
These hardened steel spring cups are ideal for engine builds, rebuilds, and performance upgrades where OEM or aftermarket cylinder head assemblies require precision spring seating. The hardened steel construction ensures longevity under repeated compression cycles and thermal stress. Commonly used in small-block and mid-sized performance engine platforms, these cups serve as critical valve train components that maintain proper spring preload and geometry.
