Ferrea E11064-1 Pro CNC Titanium Valve Spring Retainer

The Ferrea E11064-1 is a precision-engineered titanium valve spring retainer designed for high-performance Subaru EJ20 and EJ25 engine applications. This Pro CNC series retainer is specifically engineered for use with double valve springs and features a 6-degree lock angle for optimal valve train stability.

Key Features:

• Precision CNC-machined from aerospace-quality titanium alloy
• Fully heat-treated and finished to exact tolerances for maximum durability
• 40% weight reduction compared to conventional steel retainers
• Optimized for high-RPM valve train stability and reliability
• 6-degree Pro CNC design for double spring applications
• 6mm valve stem diameter compatibility
• Outside diameter: 25.40mm, Inside diameter: 15.70mm

This retainer is engineered to work with Ferrea valve springs (such as S10097) and valve locks (K10074) for complete valve train upgrade applications. The lightweight titanium construction reduces reciprocating mass while maintaining superior strength, making it ideal for turbocharged, high-performance, and drag racing applications where valve train control at elevated engine speeds is critical.

Note: Sold individually. Price is per single retainer.
