Product Details

COMP Cams is well-known for making performance parts that help engines run better, and their XFI AFM 216/228 D camshaft is a prime example for GM LS engines. This camshaft is designed to work with VVT (Variable Valve Timing) and AFM (Active Fuel Management) systems, making it a great option for a wide range of GM trucks and SUVs. If you're looking to get more out of your LS engine, especially in a heavier vehicle that uses stock gears, this camshaft can offer notable improvements.

This particular camshaft, the 358 VVT/AFM 26, features a hydraulic roller design with specific lift and duration numbers: 216/228 degrees at .050 inch lift on the intake and 214/226 degrees on the exhaust. These specs are chosen to provide excellent responsiveness and a strong pull in the mid-range power band, translating to better acceleration and overall performance. It's a popular choice for those wanting across-the-board gains without sacrificing too much low-end torque, making it suitable for daily drivers and work vehicles alike. The design aims for a noticeable improvement in how the engine feels and performs, especially when paired with the factory gear ratios.

When installing a camshaft like this, it's important to follow the manufacturer's recommended procedures. While this camshaft is designed to work with VVT and AFM systems, it's always a good idea to consult the full installation instructions from COMP Cams to ensure proper setup and to understand what other components might be beneficial for your specific build. Keep in mind that this part is not CARB approved and cannot be shipped to California.
