Ferrea E11105 Titanium Valve Spring Retainer Stem OD - 5.5mm 24mm

The Ferrea E11105 is a precision CNC-machined titanium valve spring retainer designed for high-performance Hyundai V6 engines with 5.5mm valve stems. This Pro-Series retainer is manufactured from aerospace-quality titanium alloy and features a 24mm outer diameter with an 18.3mm inner diameter, providing superior strength while reducing valvetrain weight by approximately 40% compared to steel retainers.

Key Features:

• CNC-machined from aerospace-grade titanium alloy for maximum strength and minimal weight
• Fully heat-treated and finished to exact tolerances for consistent performance
• 24mm outer diameter with 18.3mm inner diameter for proper spring retention
• Designed for 5.5mm valve stem applications
• Compatible with Ferrea valve spring S10134 and factory OEM spring seat locators
• Ideal for high-RPM racing applications where reduced reciprocating mass is critical

Ferrea titanium retainers are engineered to withstand extreme racing conditions while providing uniform load distribution and preventing valve float at high engine speeds. Each retainer undergoes extensive quality control procedures to ensure reliability in demanding performance applications.
