Not Yet Reviewed

COMP Cams Thumpr NSR Hemi Gen III/IV camshafts bring the wildly popular Thumpr sound to late model Hemi engines, while offering big power gains and no need to upgrade valve springs. The cams are made from billet steel cores for increased strength—and require no springs for a far easier installation. Great in naturally aspirated or supercharged applications, COMP Cams Thumpr NSR Hemi Gen III/IV camshafts provide excellent performance in mid- to upper-rpm ranges. Order the model designed for your vehicle and engine application.
