Product Details

The COMP Cams 721-1 is a precision-engineered titanium valve spring retainer designed for high-performance engine builds. This lightweight retainer features a 10-degree machined angle and is specifically designed to work with double valve springs measuring 1.500" to 1.550" outside diameter.

Key Features:

  • Premium titanium construction for maximum strength and minimal weight
  • 10-degree retainer angle for optimized valve geometry
  • Compatible with 1.500" to 1.550" OD double valve springs
  • Precision machined for consistent performance and proper valve train operation
  • Reduces reciprocating mass for higher RPM capability

Titanium retainers are essential components for racing and high-performance applications where reducing valve train weight is critical. The lighter weight allows for higher engine speeds while maintaining valve control and reducing stress on valve springs. This retainer is compatible with COMP Cams valve springs and most aftermarket performance valve springs within the specified diameter range.
