Product Details

The COMP Cams 603-1 valve locks are precision-engineered hardened steel retainer locks designed for high-performance street applications. These locks feature a 7-degree taper angle with a 3/8" stem diameter and single groove design for secure valve spring retainer attachment.

Key Features:

  • Hardened steel construction for superior strength and durability
  • 7-degree taper angle for proper retainer seating
  • 3/8" valve stem diameter compatibility
  • Single groove design for standard valve stem applications
  • Precision machined for consistent fitment and performance
  • Sold as a pair for one valve assembly

These valve locks are essential engine components that secure the valve spring retainer to the valve stem, preventing the spring from sliding off during operation. The hardened steel material provides excellent wear resistance under the constant stress of valve train operation, making them ideal for street performance engines where reliability is critical.
