Chry 426 Hemi Hi-Energy Hyd. Lifters

The Chry 426 Hemi Hi-Energy Hydraulic Lifters by COMP CAMS deliver the precision valve actuation that serious Mopar enthusiasts demand when building or rebuilding high-performance 426 Hemi engines. These hydraulic lifters are engineered for engines that require reliable, maintenance-free valve train operation across street, strip, and vintage racing applications. Whether you're restoring a classic muscle car or maintaining an original Hemi powerplant, hi-energy lifters provide the consistent oil pressure control needed to keep your valve events tight and predictable over thousands of miles.

Hydraulic lifters automatically adjust for valve train wear and thermal expansion, eliminating the need for manual valve lash adjustment that plagues solid lifter conversions. COMP CAMS hi-energy design uses advanced internal orifice geometry to maintain optimal oil flow and pressure stability, preventing lifter bleed-down that can cause valve float at higher RPMs or aggressive cam profiles. The robust construction handles the demands of a 426 Hemi's high-compression environment while maintaining the factory quiet operation and reliability that original equipment owners expect. Each lifter is precisely manufactured to exacting tolerances to ensure consistent preload and response across all eight cylinders.

These lifters are ideal for 426 Hemi engine blocks used in 1966–1971 Chrysler, Dodge, and Plymouth muscle cars, as well as modern crate Hemi applications where factory valve train geometry is retained. Installation requires proper engine block preparation and fresh engine oil of the correct viscosity to ensure lifter priming and initial operation. For builders combining these hi-energy lifters with performance camshafts, COMP CAMS' matched cam-and-lifter combinations eliminate guesswork and guarantee compatibility. This 16-piece set (SKU COM824-16) supplies all lifters required for a complete 426 Hemi rebuild or refresh, making it the definitive choice for authenticity and dependability.
