Ferrea E11020-1 Pro CNC Titanium Valve Spring Retainer - Single

The Ferrea E11020-1 is a single Pro CNC Titanium Valve Spring Retainer, precision-engineered for high-performance and racing engine applications. Sold individually, it is ideal for replacing a single retainer or completing a custom valvetrain build.

Key Features:

• Aerospace-grade titanium construction — CNC machined from premium aerospace quality titanium alloy for maximum strength and durability
• 40% weight reduction over conventional steel retainers, reducing valvetrain reciprocating mass for improved high-RPM performance
• Fully heat-treated and stress relieved — finished to exact tolerances for consistent, reliable performance batch to batch
• Pro CNC Series precision machining ensures a perfect fit with compatible Ferrea valve springs and locks
• Sold as a single unit (qty: 1) — part of Ferrea's E11020 retainer family

Ferrea Pro CNC Titanium Retainers are designed to work in conjunction with Ferrea competition valves, valve springs, and valve locks. Reducing retainer mass lowers the load on the valve spring, allowing the valvetrain to maintain control at higher RPM while extending component life. Compatible retainers are available for 6, 7, 8 (Super 7), and 10-degree lock groove configurations — confirm your lock groove angle before ordering.
