Comp Cams Thumpr Hydraulic Flat Tappet Cams Product images may differ from actual product appearance. Thumpr Camshafts are the hottest cams to hit the streets in more than a decade. Applying a camshaft design originally created for sports car endurance racing, they incorporate early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap. Best of all, Thumprs will not negatively impact power output or streetability. Thumpr Sound Clip Camshaft & Lifter Kits are indicated by a CL in their part number and include Camshaft and Lifters. Complete Kits are indicated by a K in their part number and include Camshaft, Lifters, Timing Chain & Gears, Valve Springs, Spring Retainers, Spring Locks and Valve Springs.
