Product Details

COMP Cams is well-known for making performance valvetrain components, and this Camshaft for GM LS engines is a prime example of their expertise. This particular camshaft, part number 689-426-13, is designed to work with VVT (Variable Valve Timing) and AFM (Active Fuel Management) systems found in many GM LS-based engines. If you're looking to get more out of your LS engine, whether it's for a performance build, an LS swap, or just to wake up your daily driver, this camshaft offers a significant upgrade over stock.

This camshaft features a specific lobe profile, identified as the 358 VVT/AFM 28, which is engineered to provide an improved powerband. It's designed to work seamlessly with the factory VVT and AFM systems, meaning you can retain these features for better fuel economy and emissions when cruising, while still getting a noticeable boost in performance when you need it. The camshaft is made from solid steel and is built to withstand the demands of a performance engine. It's a popular choice for those looking to enhance the power and torque of their GM LS engine without the complexity of deleting VVT or AFM.

When installing this camshaft, it's important to ensure you have the correct supporting components. While this camshaft is designed to work with VVT and AFM, you'll want to confirm compatibility with your specific engine's valve springs, pushrods, and timing set. Always refer to the manufacturer's installation instructions for detailed guidance and recommended parts to ensure a successful build. Please note that this camshaft is not CARB approved and cannot be shipped to California.
