5/16 Lash Cap (Hardened) .080 Thickness

The COMP CAMS 5/16 Lash Cap (Hardened) .080 Thickness is a precision valve train component engineered to maintain accurate valve lash clearance in small-block and big-block engine applications. This hardened steel lash cap set of 16 is designed for 5/16-inch valve stems and delivers the durability required in high-RPM, high-heat engine environments where consistent clearance control is critical to performance and longevity.

The .080-inch thickness is a standard specification that fits within OEM and performance rebuild tolerances. Hardened steel construction resists wear and deformation under the repeated mechanical stress of valve operation, preventing the clearance loss that leads to valve float and power loss. These caps are sized specifically for 5/16-inch valve stem diameter, ensuring proper seating and eliminating the guesswork during engine assembly. The natural steel finish provides a clean appearance while maintaining full corrosion resistance typical of hardened ferrous components in modern engine builds.

Engine builders, performance enthusiasts, and restoration shops rely on COMP CAMS lash caps when setting up fresh engines, replacing worn components, or fine-tuning valve clearance in existing powerplants. This 16-piece set covers both banks on a standard V8 configuration, or serves as a replacement kit for single-bank work with spare capacity. Whether assembling a street engine, race motor, or vintage rebuild, maintaining proper lash clearance with quality hardened caps protects valve life and ensures consistent horsepower delivery across the RPM range.
