Product Details

Manley valve spring retainers (also called spring caps) are engineered for performance and racing engines. They locate and hold the valve springs on the valve stem, and they keep valve control consistent as RPM and spring pressure rise. Manley is a well-known name in performance valvetrain and engine components.

Key Features:

  • Lightweight design reduces valvetrain mass, which helps valve control and supports higher RPM potential
  • CNC-machined for consistent fit, precision and durability
  • Heat-treated materials chosen for strength, reliability and fatigue resistance under extreme conditions
  • Built for drag racing, road racing, circle track and high-performance street engines
  • Available in a range of lock angles and spring configurations to suit different valvetrain setups

Upgrading to Manley retainers is a practical way to lighten your valvetrain and improve valve control, whether you are building a race engine or a performance street engine. Choose the variant that matches your valve spring and valve stem lock requirements.
