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, \u0026lt;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. COMP Cams?? Part# 748-1.
