COMP Cams Camshaft A6 X4 254H-11

This is the COMP Cams Xtreme 4x4 254H-11 hydraulic flat tappet camshaft, designed for AMC and Jeep inline-six engines like the 199, 258, and 4.0L. If you're looking to improve your vehicle's off-road capability or just want more grunt for towing, this camshaft can make a notable difference. It's built to give you good torque down low and strong performance in the mid-range, making it a popular choice for trucks and Jeeps that see a lot of work.

This camshaft is a well-built component from COMP Cams, a well-known name in performance engine parts. The 210 degrees of intake duration and 218 degrees of exhaust duration at .050 lift are specifically chosen to enhance torque and mid-range power. For best results, it's recommended to pair this camshaft with lower gear ratios, which helps keep the engine in its power band more effectively, especially when carrying loads or climbing hills. Keep in mind this camshaft is not for EFI applications and is best suited for carbureted setups.

When installing this camshaft, remember it's a flat tappet design, so proper lubrication during break-in is crucial to prevent premature wear. COMP Cams recommends using a break-in oil additive to ensure the lifters and cam lobes get adequate protection. This camshaft fits a wide range of vehicles, including many AMC models from the 60s and 70s, as well as various Jeep and International trucks and SUVs.
