Speedmaster PCE470.1001 1.550" OD Hardened Steel Valve Spring Seat Springs

The Speedmaster PCE470.1001 is a hardened steel valve spring seat spring designed for engine applications requiring precision valve train components. These springs feature a 1.550" outer diameter with a 0.567" inner diameter and 0.060" thickness, manufactured from hardened steel for durability and consistent performance under high-cycle operating conditions.

These valve spring seat springs are engineered to support proper valve seating and spring tension in engine assemblies, making them ideal for performance rebuilds, engine restorations, and original equipment replacement. The hardened steel construction ensures resistance to fatigue and compression set, critical for maintaining valve lift accuracy and combustion seal integrity over extended engine operation. Commonly used in small block and mid-size engine builds where aftermarket valve train upgrades are installed.

Key Features & Benefits
