COMP Cams 1964-1998 Jeep 4.0L Xtreme 4x4 197/201 Camshaft X4 242H-8

If you're looking to get more out of your Jeep 4.0L engine, especially for off-road use like rock crawling, this COMP Cams Xtreme 4x4 camshaft is a solid option. It's designed specifically for the 4.0L inline-six, which has seen duty in Jeeps from 1964 all the way through 1998. This camshaft uses updated lobe designs that give you more valve lift and duration within the engine's stock constraints, which translates directly into better torque and improved mid-range power.

This particular grind, the X4 242H-8, is well-suited for builds using stock cylinder heads and works with both carbureted and electronic fuel injection (EFI) setups. The focus here is on delivering excellent throttle response and usable torque, making it a great choice for applications where you need consistent power delivery off-road. COMP Cams has put a lot of thought into tailoring these grinds for specific Jeep 4.0L uses, and this one is aimed at maximizing responsiveness for demanding situations.

Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. It's a direct replacement for your stock camshaft, but as with any camshaft installation, it's a good idea to refer to the manufacturer's instructions for proper setup and tuning to get the most out of it.
