5/16 Chry Hemi Lash Caps (Short Cap) .080 Thick

The 5/16 Chry Hemi Lash Caps (Short Cap) .080 Thick by COMP CAMS are precision valve lash adjusters engineered for high-performance Mopar 426 Hemi engine builds. These components are essential for racers, restorers, and performance enthusiasts who demand exact valve clearance control in legendary big-block Hemi platforms. Lash caps serve as critical shims that sit atop valve stems, allowing tuners to maintain proper valve-to-rocker contact geometry and prevent premature wear while optimizing engine breathing and performance.

Manufactured from durable steel and finished in natural (bare) condition, these lash caps measure 5/16 inches in valve stem diameter and feature a 0.080-inch thickness—a specification critical for maintaining precise running clearances in solid-lifter and adjustable-lifter valvetrain configurations. The short-cap design fits within tight engine bay constraints while delivering the structural rigidity required to support valve spring pressure and prevent mushrooming or deformation under sustained RPM. Each set includes 16 caps, providing complete coverage for a full V-8 cylinder head and ensuring uniform valve train geometry across all eight cylinders.

Builders restoring original 426 Hemi engines or constructing modern performance variants will find these caps indispensable for achieving factory-correct or optimized valve clearance settings. Installation requires valve removal and precise measurement to determine the correct shim thickness, making them ideal for full-engine rebuilds, cylinder head servicing, and high-RPM race engine tuning. Compatibility is specific to 5/16-inch valve stem applications on Mopar 426 Hemi platforms; measure existing stem diameter before ordering to ensure proper fit and optimal engine performance.
