COMP Cams Thumpr NSR Camshaft 09-2022 5.7 6.4 Hemi GM Trucks Grams Performance & Design nowThe lopey idle you want. The low RPM torque you need. The COMP Cams Thumpr NSR camshaft brings the iconic Thumpr idle lope to the GEN III IV HEMI platform without sacrificing the street friendly low end pull or requiring a valve spring upgrade. What Makes the Thumpr NSR Different? Getting that racecar idle sound used to mean giving up low RPM torque a trade off that made most aggressive cams impractical for street driven HEMIs.
