The Jeep Grand Cherokee - CCA Camshafts are a remarkable addition to any performance enthusiast's setup, designed specifically for those who crave an aggressive, attention-grabbing exhaust note and exceptional horsepower gains. These camshafts are part of the renowned Thumpr series from COMP Cams, known for their ability to transform street vehicles into muscle-bound performance machines. Ideal for muscle cars and street rods, these camshafts are engineered to provide a distinctive race car idle that turns heads and delivers powerful performance on demand.

The Thumpr series camshafts achieve this remarkably throaty exhaust note and serious power boost through a combination of early intake valve opening and prolonged exhaust duration. This engineering masterpiece creates optimum overlap—a critical component for that impressive, thumping idle associated with high-performance race cars. As such, the Thumpr camshafts are a top choice for enthusiasts aiming to push their vehicles to new performance heights.

Designed for those who demand more from their vehicles, the Thumpr series requires specific drivetrain modifications to ensure optimum performance.
