Ferrea E11028 Heavy Duty Titanium Valve Spring Retainer 1.500" OD

The Ferrea E11028 is a precision CNC-machined heavy-duty titanium valve spring retainer manufactured from aerospace-quality titanium alloy, fully heat-treated and finished to exact tolerances for maximum strength and reliability. Designed for high-performance racing and extreme RPM applications, this retainer features a 1.500" outer diameter universal fit specification.

Key Features:

• 40% weight reduction compared to conventional steel retainers
• CNC machined to perfection offering superior strength and stability
• Aerospace-grade titanium construction for extreme durability
• Full heat treatment process ensures consistent performance under high stress
• Precision tolerances for proper valve spring retention and sealing
• Universal 1.500" OD design for broad application compatibility

Ferrea retainers are designed to withstand extreme combustion pressures, high-RPM operation, and elevated heat loads, making them ideal for racing engines, turbocharged applications, and high-performance street builds. The reduced rotating mass of titanium retainers allows for higher rev limits and improved valvetrain control.
