Product Details

The COMP Cams 137023 is an upgraded trunnion retaining ring specifically engineered for GM LS1, LS3, and LS7 rocker arms. This precision-manufactured component provides enhanced retention and durability compared to factory retaining rings, helping to prevent trunnion failure—a common issue in high-performance LS engine builds.

Key Features:

  • Direct replacement for factory GM LS trunnion retaining rings
  • Upgraded design provides improved retention force and reliability
  • Compatible with LS1, LS3, and LS7 rocker arm assemblies
  • Precision-engineered for proper fit and function
  • Essential upgrade for performance and racing applications
  • Helps prevent catastrophic trunnion failure under high-stress conditions

This upgraded retaining ring is a critical component for builders looking to improve valvetrain reliability in modified LS engines, particularly those running aggressive camshafts, higher valve spring pressures, or elevated RPM ranges. The enhanced design ensures the trunnion bearing stays properly seated during operation, reducing the risk of rocker arm failure that can cause severe engine damage.
