The COMP Cams Stage 2 HRT 220/230 Max Power Hydraulic Roller Cam Kit is designed to extract serious power from your vehicle. Specifically built around Low Shock Technology (LST) profiles, this camshaft provides the best average torque and horsepower of any sub-.600" lift cam tested on Gen III HEMI platforms. With a powerband from 2500–6500 RPM and the ability to rev to 6700 RPM+ using COMP’s #26918 Beehive™ valve springs, this cam is ideal for naturally aspirated street/strip builds. Whether you're installing it in a vehicle, this cam delivers mid-range punch and top-end horsepower without sacrificing driveability. The CK-Kit (Cam Kit) includes all matched valvetrain components: billet steel camshaft, performance pushrods, valve springs, retainers, locks, spring seats, and seals. When tuned properly, this cam package can produce up to +79 horsepower gains — a major performance boost for your Gen III HEMI.
