COMP Cams Camshaft GM LS 994 VVT/AFM 26

COMP Cams is well-known for making performance valvetrain components, and this XFI AFM camshaft is a prime example of their expertise for GM LS engines. If you're looking to get more grunt from your truck or heavy car, especially from off idle and throughout the entire RPM range, this camshaft is a solid choice. It's designed to work with GM's Variable Valve Actuation (VVT) and Active Fuel Management (AFM) systems, making it a direct upgrade for compatible engines without needing to delete those features.

This camshaft features a 216-degree intake duration and a 228-degree exhaust duration, with a 114-degree lobe separation angle. These specs are chosen to provide that strong off-idle torque you want for towing or just getting a heavy vehicle moving, while also boosting power higher up in the revs. It's a hydraulic roller design, which is standard for most modern LS engines and helps reduce friction compared to older flat tappet designs. The XFI designation means it uses their advanced lobe profiles for improved performance and drivability.

When installing this camshaft, remember that it's not CARB approved and cannot be shipped to California. It's a significant upgrade that changes the engine's breathing characteristics, so ensure you have the necessary supporting modifications or consult with a professional to get the most out of it. This camshaft is a great way to unlock more performance from your GM LS-powered vehicle.
