The Jeep 4.0L is used for many different tasks, from daily driving to rock crawling and even hill climbs. COMP Cams has released grinds that tailor to some of the most common applications of this proven motor. These camshafts feature new lobe designs specific to the 4.0L that allow for more duration and valve lift within the constraints of the 4.0L design. This results in better torque and mid-range power for both carbureted and EFI applications. With two grinds aimed at builds utilizing aftermarket cylinder heads and one designed for stock heads, you can choose the best cam for your specific setup and usage that provides maximum responsiveness with simple tuning.
