Ferrea E11117 Pro Series Titanium Valve Spring Retainer

The Ferrea E11117 is a high-performance titanium valve spring retainer designed for use with Ferrea dual valve spring applications. This precision-engineered component is essential for building a reliable, high-revving valvetrain system.

Key Features:

• Precision CNC-machined from aerospace-quality titanium alloy
• Fully heat-treated and finished to exact tolerances for maximum strength
• 40% weight reduction compared to conventional steel retainers
• Reduces valvetrain mass for improved high-RPM performance
• Designed for use with Ferrea dual valve spring systems
• Compatible with Toyota/Scion 2ARFE engine applications

Ferrea's Pro Series titanium retainers are manufactured to professional racing standards, providing the strength and stability demanded by high-performance engine builders. The reduced weight helps minimize valvetrain inertia, allowing for more aggressive camshaft profiles and higher operating RPM ranges while maintaining reliability. This retainer must be used with compatible Ferrea valve springs and valve locks for proper installation.
