Product Details

This COMP Cams XFI Xtreme Truck camshaft is designed for GM LS Gen III and IV engines, specifically targeting 6.0L Chevrolet and GMC trucks, but it also fits a wide range of other LS-based displacements and applications. You'll get the camshaft itself, ready for installation. This camshaft is built to make a notable difference in your engine's performance, especially in the mid and upper RPM ranges, giving you more power when you need it for acceleration or highway cruising.

The XFI 261 HR15 is a hydraulic roller camshaft, which generally means less friction and more efficient operation compared to flat tappet designs. Its 208/212 degree intake/exhaust duration at .050 lift is tuned for truck applications, aiming for a strong torque curve that doesn't sacrifice top-end horsepower. To get the most out of this camshaft, it's recommended to use it with a programmer to optimize your engine's fuel and timing maps. This ensures the engine control module works in harmony with the new cam profile for improved performance and drivability.

This camshaft is a solid option for those looking to upgrade their LS-powered truck or SUV. It's important to note that this part is not CARB approved and cannot be shipped to California. For optimal results and to ensure proper operation, always refer to the manufacturer's installation instructions and consider consulting with a professional mechanic for installation and tuning, especially when making significant internal engine changes.
