Ferrea E11017-1 Pro CNC Titanium Valve Retainer 6 Degree Dual Spring

The Ferrea E11017-1 is a high-performance Pro CNC titanium valve retainer designed for Nissan VG30D and VG30DTT engines. This precision-engineered component is CNC-machined from aerospace-quality titanium alloy and fully heat-treated to exacting tolerances for maximum strength and durability.

Key Features:

• 40% lighter than stock steel retainers while offering twice the strength
• 6-degree valve angle design for dual valve spring applications
• Precision CNC-machined from aerospace-grade titanium
• Fully heat-treated and stress-relieved for molecular integrity
• Reduces valvetrain weight for improved cam lobe response at higher RPMs
• Allows higher engine rev capability with reduced valve float

By significantly reducing valvetrain mass, this titanium retainer improves valve control and allows for more aggressive camshaft profiles and higher RPM operation. The reduced reciprocating weight enhances throttle response and helps prevent valve float under extreme racing conditions. Designed to work specifically with Ferrea dual valve springs for optimal performance and reliability in high-performance and racing applications.
