What is the primary benefit of the XFI VVT camshaft?

The XFI VVT camshaft offers improved power gains over stock, particularly in modified engines. Its asymmetrical VVT intake profiles help optimize performance across a broader RPM range by working with the factory VVT system.

Does this camshaft come with all the necessary hardware for installation?

This camshaft is sold as the camshaft itself. It's recommended to consult the manufacturer's installation guide for a complete list of required components and hardware, as some parts may need to be reused from the original engine or purchased separately.

Is this camshaft compatible with engines that do not have VVT or AFM?

This camshaft is specifically designed for GM Gen IV LS engines that are equipped with both Variable Valve Timing (VVT) and Active Fuel Management (AFM). It is not intended for use in engines lacking these systems.

Product Details

This is the COMP Cams XFI VVT hydraulic roller camshaft, part number 189-424-13, designed for GM Gen IV LS engines equipped with Variable Valve Timing (VVT) and Active Fuel Management (AFM). If you're looking to get more power out of your modified LS engine, this camshaft is a solid option. It's built to work with the factory VVT system, allowing for optimized performance across a wider RPM range than a traditional camshaft.

COMP Cams developed this camshaft with more asymmetrical VVT intake profiles. This advanced design helps to achieve notable power improvements over stock, especially in engines that have other modifications. The camshaft features a 218-degree intake duration and a 230-degree exhaust duration, with a 112-degree lobe separation angle, which is a popular setup for street-driven vehicles that see a lot of use. It's a hydraulic roller camshaft, meaning it uses roller lifters to reduce friction and wear compared to flat tappet designs, contributing to its longevity and efficiency.

This camshaft fits a wide range of GM vehicles, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and Chevrolet Camaro. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. For installation, you'll want to refer to the manufacturer's instructions to ensure proper setup, especially concerning the VVT system and any other supporting modifications needed for optimal performance and reliability.
