1964-91 Chevrolet / GMC Big Block Valve Spring Retainers

Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams® Steel Retainers are the perfect solution to this problem.

COMP® engineers used 3D CAD with FEA to design retainers with a modern and advanced contoured top profiling for lower stress, increased lift and a reduction in mass. The retainers are CNC-machined to exact tolerances using CAD/CAM software.

All COMP® retainers use only high-grade SAE 4140 chromemoly steel with no lead, 0.04% sulfur and a black oxide finish to prevent corrosion. COMP Cams® Steel Valve Spring Retainers offer both unmatched looks and superior performance that set the industry standard.
