Product Details

Manley valve lash caps are engineered to protect valve stem tips in high-performance and racing engines. These precision wear caps are constructed from heat-treated 4140 steel alloy, providing exceptional strength and durability to withstand the demanding conditions of high-RPM operation.

Key Features:

  • Heat-treated 4140 steel alloy construction for maximum durability
  • Protects valve stem tips from wear and erosion caused by rocker arm contact
  • Non-rotating design minimizes valve tip wear compared to standard caps
  • Precision manufactured to ensure proper fit and consistent valve clearances
  • Can be used to adjust valve clearances or achieve required valve stem protrusion
  • Sold as a set of 4 caps

Manley Performance has been manufacturing premium valvetrain components since 1966, with a focus on delivering race-proven quality at competitive prices. These valve lash caps are designed to extend valve life and maintain consistent performance in competitive engines where durability and precision are critical.

Overall very much satisfied with communications and emails sent while waiting on product to arrive. Fast shipping and prompt courteous service. Thank You.
