Product Details

Starting with a 212 intake and 224 exhaust duration at .050 lift, this COMP Cams FSL camshaft is specifically ground for GM Gen IV LS2, LS3, and L92 engines that are equipped with Active Fuel Management (AFM) and do not have Variable Valve Timing (VVT). This camshaft is designed to work with your engine's stock valve springs and factory computer tune, making installation straightforward and avoiding the need for additional upgrades in many cases. It's a 50-state legal grind, meaning it meets emissions standards across the country, which is a notable advantage for many owners.

The FSL (Fuel Saving Legal) series camshafts from COMP Cams are engineered to provide significant power gains without compromising emissions compliance. For your LS-based engine, this particular grind can result in an increase of 30 to 47 horsepower at peak power. This improvement comes from optimized valve timing that allows the engine to breathe more efficiently. The hydraulic roller design ensures smooth operation and longevity, a standard feature in modern GM LS engines.

This camshaft fits a wide range of GM vehicles, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, and GMC Yukon. It's a solid option if you're looking to boost your engine's performance while staying compliant with emissions regulations and utilizing your existing valvetrain components. Always refer to the manufacturer's installation instructions for specific details regarding your application.
