Ev Hyd Roller Lifter Set Gen III Hemi Drop-In

The COMP CAMS EV Hyd Roller Lifter Set Gen III Hemi Drop-In is a hydraulic roller lifter assembly engineered as a direct bolt-on upgrade for Mopar Gen III Hemi engines. This complete 16-piece lifter set delivers the precision valve actuation required for high-performance engine builds while maintaining the durability and ease of installation that make drop-in solutions attractive to builders and enthusiasts alike.

Each lifter features a 0.842-inch outer diameter (OD) profile optimized for Evolution-series roller technology. The hydraulic design automatically compensates for mechanical wear and thermal expansion, eliminating manual valve lash adjustment and reducing the potential for valve train noise. The roller design minimizes friction between lifter and camshaft lobe, improving efficiency and extending component life compared to flat-tappet designs. Set of 16 provides complete coverage for one engine block.

This lifter set is purpose-built for Gen III Hemi applications—including Dodge, Chrysler, and Jeep powerplants—where factory or performance camshaft upgrades demand valve train components matched to the engine's specifications. The drop-in configuration means no block modifications are required; lifters install into existing lifter bores without additional machine work. Engine builders, restoration specialists, and high-output Hemi engine owners rely on COMP CAMS lifters to provide consistent performance across multiple heat cycles and extended duty.
