Chevy V8 DLC Hyd Lifter Set - 16pk .842 Dia.

The Chevy V8 DLC Hyd Lifter Set - 16pk .842 Dia. from COMP CAMS represents a purpose-built solution for small-block and big-block Chevrolet V8 engines requiring hydraulic valve lifter replacement or upgrade. These lifters are essential components in any serious engine rebuild, restoration, or performance modification where valve train reliability and precise clearance control are non-negotiable. Whether you're refreshing a stock engine, preparing a weekend cruiser, or building a competition platform, quality hydraulic lifters directly impact valve actuation consistency, engine longevity, and overall drivability.

These COMP CAMS hydraulic lifters feature a .842-inch diameter bore, a standard specification for most Chevrolet V8 applications, and incorporate DLC (Diamond-Like Carbon) coating technology on critical wear surfaces. The DLC treatment dramatically reduces friction between the lifter body and cylinder wall, extends service life under high-RPM operation, and minimizes valvetrain noise that plagues worn lifter sets. The 16-piece set provides enough lifters for a complete V8 engine (eight intake and eight exhaust lifters), eliminating the guesswork of partial replacements and ensuring matched valve train geometry across all eight cylinders. Hydraulic lifters self-adjust for lash, meaning zero valve adjustment is required after installation—a critical advantage for street and mild performance engines.

Technicians and enthusiasts restoring or upgrading classic Chevrolet V8s, from 283 to 454 models, depend on this lifter set to maintain OEM-correct function while benefiting from modern coating durability. Installation requires removal of the valve covers and lifter valley cover, and lifters must be properly soaked in clean engine oil before startup to ensure full hydraulic charge. These lifters perform identically to factory equipment in stock applications but excel in modified engines where higher valve spring pressures and extended RPM ranges demand superior material science. Verify your engine's specific lifter bore diameter before ordering to ensure perfect fitment.
