1.400 C/M Valve Spring Retainers - 10-Deg

The PAC Racing Springs 1.400 C/M Valve Spring Retainers with 10-Degree angle geometry deliver precision engineering for high-performance engine builds. This set of 16 chromoly retainers is engineered to manage aggressive valve spring loads while maintaining reliable seating and consistent performance across extended rpm ranges. Built from 300 series chromoly material, these retainers provide the strength and durability required in competitive racing and performance applications where spring pressures demand robust component selection.

Each retainer features dual spring compatibility with 1.067-inch and 0.785-inch OD steps, accommodating 1.459-inch dual spring configurations. The 10-degree valve angle matches modern performance cylinder head designs and ensures proper valve geometry alignment. Chromoly construction resists deformation under high spring pressures and thermal cycling, critical factors in sustained high-rpm operation. The precision machining and tight tolerances guarantee consistent fitment across all 16 pieces in the set, eliminating variance that can compromise valve train geometry and performance consistency.

This component set is specified for builders and competitors who demand exact fitment and repeatable performance in small-block and performance engine platforms. PAC Racing Springs valve spring retainers are engineered to work within complete valve spring assemblies—retainer selection must account for spring pressure, coil bind characteristics, and installed height requirements. Verify compatibility with your specific dual spring assembly before ordering to ensure proper valve train geometry and reliable operation at target rpm levels.

Performance engine builders rely on PAC Racing Springs components for consistency and durability in competitive and high-output applications. Complete valve train packages demand component-level precision—these chromoly retainers provide the structural integrity and concentricity required to maintain valve geometry under load. The 10-degree configuration addresses modern performance head designs, making this set relevant for contemporary small-block builds targeting sustained high-rpm reliability.
