Manley Spring Retainer, RET-TENSILE MAX SUPER 7

The Manley RET-TENSILE MAX SUPER 7 spring retainer is forged from high-strength 4140 steel, a material chosen for its excellent fatigue resistance under extreme stress. This is a critical component in your engine's valvetrain, working to securely hold the valve spring in place during rapid open-close cycles. For builders pushing their engines hard, whether for racing or serious performance street use, the reliability of these components is paramount. Manley has a long history of producing well-built parts for demanding applications, and this retainer is no exception.

This retainer features a tensile max super 7 design, indicating it's engineered to handle the significant forces generated by high-lift camshafts and stiff valve springs. The precise machining ensures a proper fit onto the valve stem, preventing any unwanted movement or wear. When you're rebuilding a performance engine, especially one that will see high RPMs and aggressive driving, using components like these Manley retainers can make a notable difference in the longevity and consistency of your valvetrain. They are designed to work with Manley's own line of performance valve springs, ensuring a matched system for optimal performance.

This set includes 16 retainers, enough for a typical V8 engine. While these are a direct replacement for many performance applications, always consult your engine build specifications and Manley's technical documentation to confirm compatibility with your specific valve springs and camshafts. Proper installation is key to valvetrain health, so ensure you follow recommended procedures for seating and assembly.
