Product Details

This COMP Cams Xtreme 4x4 camshaft features a 206/214 duration split, designed specifically for AMC and Jeep inline-six engines like the 199, 258, and 4.0L. It's built as a hydraulic flat tappet camshaft, making it a solid stock replacement option that aims to give you a noticeable boost in low-end torque and throttle response. Keep in mind this camshaft is not intended for use with Electronic Fuel Injection (EFI) systems.

When you're looking to get more out of your AMC or Jeep inline-six, a camshaft upgrade like this one can make a real difference. The specific lift and duration numbers are chosen to enhance the engine's breathing at lower RPMs, which is exactly what you want for improved off-road performance or just better everyday drivability. It's a well-built component that aims to provide a more engaging driving experience without requiring extensive modifications, fitting a wide range of vehicles from the 1960s through the early 1990s, including models like the Jeep CJ series, AMC Concord, and International Scout.
