The COMP Cams Stage 3 HRT 228/236 Max Power Hydraulic Roller Master Cam Kit is built to push the performance envelope of your vehicle. This aggressive cam profile delivers significant torque in the mid-range and a dramatic increase in horsepower at higher RPMs, making it ideal for heavily modified builds. Designed to complement ported cylinder heads, stroker cranks, long-tube headers, and other power-adders, this camshaft takes full advantage of the Gen IV HEMI’s high-lift airflow capabilities. With an RPM operating range of 2,200–7,400, and the potential to exceed 7,500 RPM when paired with COMP's #7230 valve springs, this camshaft is capable of adding up to 105 horsepower with proper tuning and supporting modifications.
