COMP Cams Steel Valve Spring Retainers CNC-Machined SAE 4140 Chromemoly

COMP Cams Steel Valve Spring Retainers — CNC‑machined from high‑grade SAE 4140 chromemoly steel for maximum strength and durability. Designed for high‑pressure, large‑diameter valve springs, these retainers deliver reliable spring control and long service life. Key Features Precision CNC machining: Manufactured to exact tolerances with CAD/CAM to ensure perfect fit and concentricity. Optimized geometry: 3D CAD and FEA‑driven contoured top profiling reduces stress, lowers mass and improves valve lift response. Premium material: SAE 4140 chromemoly steel for superior fatigue resistance and durability; lead‑free construction. Engineered for high loads: Ideal for high pressure springs found in performance and racing applications. Whether you are building a high‑revving race engine or upgrading a performance street motor, COMP Cams steel retainers provide the strength and precision needed to maintain valve train stability under extreme conditions. Benefits: improved spring control, reduced retainer mass, increased component life, and consistent valve timing at high RPM.
