This is the COMP Cams Xtreme Energy XR258R-12 hydraulic roller camshaft, designed for Chrysler Magnum engines. It's a popular choice for those looking to improve the performance of their computer-controlled Mopar V8s, offering a noticeable bump in power and torque without requiring major modifications. This camshaft is specifically tuned for optimal performance in applications like the Dodge Ram, Chrysler Cordoba, and Plymouth Barracuda, among many others.

The XR258R-12 features a 206-degree intake and 212-degree exhaust duration at .050 inch lift, with a .454 inch intake and .462 inch exhaust lift. These specifications are carefully chosen to provide a strong idle and excellent mid-range power, making it suitable for street-driven vehicles.

This camshaft is designed to work with factory computer controls, making the tuning process more straightforward for many builds.

When installing this camshaft, it's important to ensure you have the correct valve springs, pushrods, and potentially lifters to match its specifications. COMP Cams recommends using their matching valve springs for optimal performance and reliability. While this camshaft is designed for a wide range of Chrysler and Dodge vehicles from the 1960s through the late 1990s, always double-check the fitment guide to confirm compatibility with your specific year and model. This camshaft is not CARB approved and cannot be shipped to California.
