About this part

Product Details

Starting with a 220 intake duration and 232 exhaust duration at .050 lift, this COMP Cams XFI AFM camshaft is built to unlock more top-end power in your modified GM Gen IV LS2 or LS3 engine. It's a hydraulic roller camshaft, meaning it uses roller lifters to reduce friction and wear compared to flat tappet designs, allowing for more aggressive lobe profiles and better performance. This camshaft is specifically designed to work with engines featuring Active Fuel Management (AFM), often referred to as Displacement on Demand (DOD), and is intended for those looking to significantly enhance their engine's output, particularly in the upper RPM range.

To get the most out of this camshaft, you'll need to make supporting modifications. The extended description notes that a higher stall torque converter, re-geared rear differential, and aftermarket headers are essential for optimal performance. This isn't a simple drop-in part; it's part of a performance build where you're aiming for substantial power gains. The XFI line from COMP Cams is known for its advanced lobe designs that provide a strong powerband, and this particular grind is tailored for modified AFM engines that often have limitations from the factory cylinder deactivation system.

This camshaft fits a wide range of GM vehicles, including popular models like the Chevrolet Silverado 1500, GMC Yukon, and Chevrolet Tahoe. It's a significant upgrade for enthusiasts looking to push the performance envelope of their LS-based engine. Remember that this camshaft is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting modifications and understand the installation requirements before purchasing.
