COMP Cams® Xtreme 4×4 Camshafts for Jeep/AMC 4.0L 1999-2006 Applications

Introducing two new camshafts for the Jeep 4.0L 1999-06 applications that are each designed for a specific use, providing more power for EFI engines with both stock and aftermarket cylinder heads.

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 EFI applications.

With one grind aimed at builds utilizing stock cylinder heads and valve springs (No Springs Required) and one designed for aftermarket heads, you can choose the best cam for your specific setup that provides maximum responsiveness with simple tuning.
