COMP Cams CR Series Camshafts
Give your Mustang more muscle! COMP Cams CR Series camshafts increase power and torque capabilities throughout the curve. They greatly improve upon stock Coyote camshafts and work without modifications to the engine's cylinder heads or phasers. Camshafts are the best way to unlock the power potential of your Coyote engines. The CR Series is offered in three stages for naturally aspirated and turbo engines, as well as two separate grinds for blower applications. Designed to be a direct replacement, the CR Series camshafts, they are compatible with the stock valve springs and the new Ford mid-lock phaser system—without requiring limiters or any other phaser modifications.
