Chevy V8 DLC Hyd. Lifter Set .842 Dia.

The Chevy V8 DLC Hydraulic Lifter Set with .842-inch diameter is an essential component for anyone rebuilding, modifying, or restoring a classic or modern Chevrolet V8 engine. Hydraulic lifters are critical to proper valve operation, converting camshaft motion into precise valve timing through fluid pressure. This COMP CAMS lifter set is engineered for small-block and big-block Chevy applications where maintaining OEM-spec valve train geometry is non-negotiable for reliability and performance. Whether you're performing a complete engine rebuild or upgrading your valve train during a performance modification, quality hydraulic lifters directly impact cold-start noise reduction, fuel efficiency, and overall engine longevity.

COMP CAMS hydraulic lifters employ precision engineering with a DLC (Diamond-Like Carbon) coating that reduces friction and wear against the camshaft lobe, extending service life and improving efficiency. The .842-inch diameter specification ensures proper clearance and fit within your Chevy V8 lifter bore, a critical tolerance that cannot be compromised. These lifters maintain consistent oil pressure to eliminate valve train slack while minimizing the hammering and noise that indicates worn hydraulic lifters. The DLC coating also provides superior scuff resistance compared to standard steel lifters, making these units ideal for higher-RPM applications and modified engines running increased valve spring pressures.

This lifter set suits both street and performance builds on small-block Chevy V8s (327, 350, 383) and big-block applications (396, 427, 454), provided your engine uses this specific lifter bore diameter. Installation requires proper engine disassembly, careful cleaning of lifter bores, and new oil during break-in to ensure lifter preload and operation. Always verify compatibility with your specific camshaft profile and engine block before ordering—incorrect lifter sizing leads to catastrophic valve train failure. Pair this set with quality engine oil and follow COMP CAMS torque specifications for reliable performance on the road or track.
