Ferrea E12001 Titanium Valve Spring Retainer Super 7 Degree LS1/LS7 5/16 Stem

The Ferrea E12001 is a precision CNC-machined titanium valve spring retainer designed specifically for LS1 and LS7 engines using 5/16-inch valve stems. This Pro Series retainer features a Super 7 degree configuration with a 1.210-inch outside diameter, engineered for dual valve spring applications and high-performance racing environments.

Key Features:

• Precision CNC-machined from aerospace-grade titanium alloy
• Super 7 degree valve lock groove angle for optimal valve stem geometry
• 1.210-inch outside diameter for dual spring applications
• Fully heat-treated and finished to exact tolerances
• 40% weight reduction compared to conventional steel retainers
• Compatible with 5/16-inch (8mm) valve stems
• Designed for LS1 and LS7 engine platforms

Ferrea's titanium retainers offer superior strength and stability while dramatically reducing valvetrain mass, allowing for higher RPM operation and improved valve control. The aerospace-quality material and precise manufacturing tolerances ensure reliable performance in extreme racing conditions, helping prevent valve float and maintaining consistent valve timing at high engine speeds. These retainers work with compatible Ferrea dual valve springs and 7-degree valve locks for complete valvetrain reliability.
