Speedmaster PCE270.1008 valve spring retainers are precision-machined from chromoly steel, delivering superior strength and durability over standard stamped-steel or aluminum retainers. Featuring a 1.500" outer diameter, 1.130" inner diameter, and 7-degree taper angle, these retainers are designed to work with 11/32" valve stems for a secure, reliable lock-groove interface under high-RPM and high-lift conditions.
Engineered for performance engine builds where valve train integrity is critical, these chromoly steel retainers resist deformation and fatigue associated with aggressive spring pressures. Whether you're building a street performance or race engine, the Speedmaster PCE270.1008 retainers provide a precise, consistent fit that helps maintain proper valve spring installed height and overall valve train geometry.
