The COMP Cams steel valve retainer for 1.500"–1.550" spring diameters is machined from SAE 4140 chromemoly and black oxide finished to match high‑load valve spring applications. Engineers used 3D CAD and FEA to refine a contoured top profile that lowers stress and reduces mass; CNC machining yields tight tolerances and reliable lock angle for a variety of valve stem sizes.
