Product Details

This COMP Cams Thumpr NSR camshaft is designed to give your 2009 and newer Dodge 5.7L or 6.4L HEMI engine that unmistakable aggressive idle lope while also unlocking significant power gains. You get the sound and performance often associated with race cars, but engineered to work with your street-driven HEMI. This camshaft is the core component for achieving that signature Thumpr sound without needing to swap out your valve springs, which simplifies the installation process.

COMP Cams engineers have focused on optimizing the intake and exhaust lobes to ensure you don't sacrifice the low-RPM torque that's crucial for everyday driving. While this camshaft provides excellent performance in the mid to upper RPM range, you can expect only small losses below 2500 RPM. For VVT-equipped GEN IV HEMI engines, COMP Cams recommends using a phaser limiter or lockout kit, along with an ECU tune and DOD deletion, to get the most out of this camshaft and ensure proper operation.

This camshaft is a solid option for owners looking to significantly change the character of their HEMI engine. It fits a wide range of vehicles, including popular models like the Dodge Challenger, Dodge Charger, Chrysler 300, and Ram trucks. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for complete details on required supporting modifications and procedures.
