The Speedmaster PCE470.1001 valve spring seats are precision-manufactured from hardened steel, measuring 1.550" outer diameter, 0.567" inner diameter, and 0.060" thick. Hardened steel construction provides excellent durability and wear resistance, helping to maintain consistent valve spring pressure and protect cylinder head surfaces under demanding engine conditions.
These valve spring seats serve as a critical interface between the valve spring and the cylinder head, ensuring proper spring alignment and load distribution. Verify your engine's valve spring and head specifications match the listed dimensions before ordering to ensure correct fitment.
