Speedmaster PCE470.1005 1.640" OD Hardened Steel Valve Spring Cups, 0.040" Thick

Speedmaster PCE470.1005 valve spring cups are precision-engineered hardened steel components designed for high-performance engine applications. With a 1.640" outer diameter, 0.710" inner diameter, and 0.040" wall thickness, these cups provide the durability and load-bearing strength required in demanding powersports and racing engines where reliable valve spring support is critical.

These hardened steel valve spring cups ensure consistent valve train geometry and support proper spring preload in high-RPM environments. The robust construction resists deformation under sustained engine stress, making them ideal for engine builds, restorations, and performance modifications. Compatible with PS8005 spring configurations, these cups integrate seamlessly into valve spring assemblies for muscle cars, hot rods, and competition engines.
