3/8in Lash Caps (Hardened) .080in Thickn

The COMP CAMS 3/8in Lash Caps (Hardened) .080in Thickness is a precision valve train component engineered for small-block and mid-block engine applications. These hardened steel lash caps fit 3/8-inch valve stems and are designed to maintain critical rocker arm geometry while protecting valve tips from wear and deformation during high-lift, high-RPM operation. Each cap is individually precision-manufactured to strict tolerances, ensuring consistent valve lash management across all eight cylinders.

At 0.080 inches thick, these lash caps provide the material density required to withstand repeated impact loading from rocker arms without permanent deformation or fracturing. The hardened steel construction resists galling and scoring, which extends the service life of both the cap and the valve stem itself. COMP CAMS has engineered these caps for use in both stock and performance engine builds, making them suitable for everything from classic muscle car restorations to modern stroker applications where valve train reliability is non-negotiable.

These lash caps are essential when upgrading to roller rockers, installing higher-lift camshafts, or rebuilding a cylinder head after valve recession. Engine builders and serious enthusiasts rely on OEM-quality lash caps to maintain proper valve geometry and prevent catastrophic valve train failure. Sold as a single cap, so builders should order the quantity needed for their application—typically eight for a V8 engine or four for an inline four-cylinder. Natural finish; no special finishing required for installation.
