Product Details

This is the COMP Cams FSL Hydraulic Roller Camshaft, part number 646-200-13, designed for GM Gen IV LS engines that use a three-bolt or single-bolt camshaft design and are equipped with AFM/DOD (Active Fuel Management/Displacement on Demand). If you're looking to get more power out of your LS engine without a complex build, this camshaft is a solid option. It's engineered to work with your stock components and tune, making the installation straightforward for many applications.

What sets this camshaft apart is its 50-state legal grind, meaning it meets emissions regulations in all states, including California. This is a notable advantage for many owners. The FSL series camshafts are designed to deliver improved peak power, with gains typically ranging from 30 to 47 horsepower, and this specific grind is noted to produce over 32 HP with stock components and tune. This improved performance comes without the need for an upgraded valve spring kit or a custom tune, simplifying the installation process and keeping costs down. The camshaft features a 208/220 degree intake and exhaust duration at .050 inch lift, with a 114-degree lobe separation angle, which is a popular configuration for street-driven vehicles seeking a noticeable power bump.

This camshaft is a great choice for a wide range of GM vehicles, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, and GMC Yukon. It's specifically designed for GM LS Gen IV engines without Variable Valve Timing (VVT), but WITH AFM/DOD. While it works with stock components, always refer to the manufacturer's installation instructions for specific details regarding hardware and procedures to ensure proper fitment and performance.
