Gen III Hemi Hyd Roller Camshaft Stage 3

The Gen III Hemi Hyd Roller Camshaft Stage 3 from COMP Cams is engineered for serious Dodge and Chrysler Hemi engine builders seeking reliable mid-range power gains without exotic fuel requirements or complex tuning. This hydraulic roller cam delivers the dependable valve control needed for street and mild performance applications, making it an ideal upgrade for owners who want measurable torque and horsepower improvement from their Gen III Hemi platform while maintaining everyday drivability and long-term durability.

COMP Cams' hydraulic roller design eliminates the noise and maintenance headaches of flat-tappet cams while offering superior valve train geometry and reduced friction during operation. The Stage 3 profile is optimized for Gen III Hemi applications, providing aggressive lift and duration specifications that unlock additional cubic feet per minute through the cylinder head without requiring premium fuel or high-rpm stabilization systems. The roller lifter design ensures consistent valve timing across thermal cycles, preserving the cam profile integrity and extending component life even under sustained performance driving conditions.

Buyers upgrading Gen III Hemi-equipped vehicles—including 2003–2008 Dodge Ram trucks, Chargers, and Magnum models—will find this camshaft a straightforward bolt-in upgrade that works with factory intake and exhaust manifolds. Installation requires basic mechanical knowledge and standard tools; no custom head porting, valve spring replacement, or extensive tuning is necessary, though a professional engine builder can validate your specific combination for optimal results. This camshaft pairs effectively with mild intake manifold improvements and aftermarket exhaust to deliver noticeable mid-range punch ideal for towing, acceleration response, and weekend performance driving.
