Ferrea E11097-1 Pro CNC Titanium Valve Spring Retainer

The Ferrea E11097-1 is a precision-engineered Pro CNC Series titanium valve spring retainer designed for high-performance engine builds. This single retainer is CNC-machined from aerospace-quality titanium alloy and fully heat-treated to exact tolerances, delivering exceptional strength and durability for demanding racing applications.

Key Features:

• Precision CNC-machined from aerospace-grade titanium alloy
• 40% weight reduction compared to conventional steel retainers
• Fully heat-treated and finished to exact tolerances
• Designed for use with Ferrea double valve springs
• Compatible with Toyota 2ZZ-GE engines (Celica, Lotus Elise, Exige)
• Reduces valvetrain mass for improved high-RPM performance

Ferrea's Pro Series retainers are engineered to withstand extreme racing conditions and high-RPM operation. The significant weight reduction over steel retainers helps minimize valvetrain inertia, allowing for more aggressive camshaft profiles and higher rev limits. Each retainer is manufactured to professional racing standards, making it the choice of engine builders and racers worldwide.

Note: This part number represents a single retainer. Use with compatible Ferrea valve springs (such as S10123) and valve locks (K10072 or equivalent) for complete installation.
