Product Details

The COMP Cams 729-1 is a precision-engineered titanium valve spring retainer designed for high-performance engine builds. This lightweight retainer features a 10-degree 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 angle design for optimal valve train geometry
  • Compatible with 1.500" to 1.550" OD double valve springs
  • Reduces reciprocating mass for higher RPM capability
  • Precision machined for consistent valve spring seating
  • Ideal for racing and high-performance street applications

Titanium retainers are a critical upgrade for serious performance builds, offering significant weight reduction over steel retainers while maintaining exceptional durability. The reduced mass allows for more aggressive cam profiles and higher engine speeds without valve float. COMP Cams retainers are manufactured to exacting tolerances to ensure proper valve train operation and longevity.
