COMP Cams Steel Valve Spring Retainer Sets CNC-Machined SAE 4140 Chromemoly

COMP Cams Steel Valve Spring Retainer Sets — CNC-Machined SAE 4140 Chromemoly Optimized for high-pressure, large-diameter valve springs . COMP Cams steel retainers are engineered to withstand increased spring loads while reducing mass and stress for improved valvetrain performance and longevity. Premium material: Machined from high-grade SAE 4140 chromemoly steel for superior strength and fatigue resistance. Advanced design: 3D CAD development with FEA-validated contoured top profiling lowers stress and supports higher lift applications. Precision manufacturing: CNC-machined to exact tolerances using CAD/CAM processes for repeatable fit and reliability. Performance benefits: Reduced mass improves valve control at RPM, while the contoured profile minimizes stress concentrations for extended service life. Safe composition: Manufactured without lead for compliance and safer handling. Ideal for builders and racers upgrading to larger valve springs or higher lift cams, COMP Cams steel retainers deliver the strength and precision required for aggressive valvetrain setups.
