Gen III Hemi Hyd Roller Camshaft

The COMP CAMS Gen III Hemi Hydraulic Roller Camshaft (part number 201-306-17) is a performance-focused cam designed specifically for modern Mopar Gen III Hemi engines. This NSR Stage 3 HRT hydraulic roller camshaft delivers aggressive valve lift and duration specifications engineered to maximize power output across a broad RPM band. With 0.632-inch intake lift and 0.609-inch exhaust lift, paired with 281-degree intake and 284-degree exhaust duration, this camshaft transforms engine breathing characteristics and fuel delivery timing for measurable horsepower and torque gains.

The 117.5-degree lobe separation angle balances overlap and scavenging efficiency, while the 2,100 to 7,400 RPM operating window positions this cam for street-to-strip versatility. Hydraulic roller technology eliminates the friction and maintenance demands of flat-tappet designs, offering smoother operation and extended component life. The generous lift and duration figures demand proper fuel mapping and engine management tuning to unlock full potential; stock ECU parameters may require recalibration for optimal combustion and emission control. This specification suits builders targeting serious performance upgrades without full engine displacement increases.

This camshaft is engineered for Gen III Hemi applications—the 5.7L and 6.1L pushrod architecture found in Dodge Chargers, Challengers, Magnums, and light-duty trucks from the 2003–2010 model years. Builders installing this cam should verify valvetrain clearances, confirm rocker arm geometry compatibility, and inspect pushrods and lifters for wear. Pairing with matching valve springs, quality pushrod tube setups, and a trusted performance fuel system ensures reliable operation at peak boost and high-rpm conditions.
