COMP Cams Camshaft GM Gen Iv LS2/LS3 AFM

If you're looking to get more torque and overall power out of your GM Gen IV LS truck or heavy application, this COMP Cams XFI AFM camshaft is a solid option. It's designed to work with the factory Active Fuel Management (AFM) system, offering a significant improvement over stock AFM cams without requiring a full conversion. This camshaft is a popular choice for those wanting a noticeable boost in performance for towing or hauling, providing a great all-around torque curve that benefits these types of vehicles.

This camshaft features a hydraulic roller design, which is standard for most modern LS engines and helps ensure smooth operation and longevity. The grind specifications, 212 degrees of intake duration and 224 degrees of exhaust duration at .050 lift (210/222 advertised), are carefully chosen to balance improved power output with drivability for trucks and other heavy-duty applications. It’s built to COMP Cams' standards, meaning you can expect a well-built component that’s ready to perform. Remember that when installing a camshaft, it's crucial to follow the manufacturer's recommended procedures, which often include using new lifters, checking valve springs, and ensuring proper break-in oil is used.

This camshaft is compatible with a wide range of GM vehicles equipped with the Gen IV LS engine, including models like the Chevrolet Silverado 1500, GMC Yukon, and Chevrolet Tahoe. It's a direct replacement for the stock AFM camshaft, making the installation process more straightforward for experienced DIYers or professional mechanics. Always consult the COMP Cams installation instructions for specific details regarding your vehicle's setup and any other components you might need to complete the job, such as gaskets or timing sets.
