The COMP Cams Stage 3 HRT 224/234 Max Power Hydraulic Roller Master Cam Kit is the ultimate performance cam package for your vehicle engine using stock pistons. Designed to extract every ounce of power from the high-lift airflow capabilities of Gen IV HEMI cylinder heads, this cam provides maximum horsepower and race-level RPM stability—without compromising durability. Operating from 2,100–7,400 RPM, and capable of 7500+ RPM with COMP’s #7230 valve springs, the 224/234 grind makes massive gains in both mid-range torque and top-end power. Built with Low Shock Technology (LST), the camshaft reduces valve train stress, increasing reliability under extreme conditions. The Master Cam Kit (MK-Kit) includes everything needed for a high-performance valvetrain overhaul—camshaft, VVT phaser limiter, pushrods, premium springs, steel retainers, valve locks, spring seats, valve seals, and drop-in performance lifters.
