Ferrea E11109 Titanium Valve Spring Retainer

The Ferrea E11109 is a precision-machined titanium valve spring retainer engineered for high-performance and racing engine applications. As part of Ferrea's Pro CNC Series retainer lineup, this retainer is designed to reduce valvetrain reciprocating mass, allowing engines to rev higher with improved reliability and valve control.

Key Features:

• Precision CNC machined from aerospace-grade titanium alloy
• Fully heat-treated for maximum strength and durability
• Significantly lighter than OEM steel retainers, reducing valvetrain inertia
• Machined to exact tolerances for consistent, reliable valve lock fitment
• Designed for use with Ferrea valve springs and competition valves
• Ideal for performance street, road racing, and drag racing applications

Upgrading to titanium retainers is a critical step in any serious valvetrain build. By reducing the weight of reciprocating components, the Ferrea E11109 helps prevent valve float at high RPM, extends valvetrain component life, and supports more aggressive camshaft profiles. Ferrea retainers are trusted by professional racing teams across Formula 1, NASCAR, IndyCar, and drag racing programs worldwide.
