Product Details

If you're looking to improve the low-end torque for your Chevrolet Big Block GEN VI engine, especially for towing or RV applications, this COMP Cams Xtreme Energy camshaft is a solid option. This hydraulic roller camshaft, part number XR258HR-10, is designed to work with your stock intake and exhaust manifolds, making installation more straightforward. It's a popular choice for those who need more pulling power from their truck or motorhome.

The XR258HR-10 features a 206-degree intake and 212-degree exhaust duration at .050 inch lift, with a .462 inch intake and .470 inch exhaust lift. These specifications are tuned to deliver strong performance in the lower RPM range, which is crucial for getting heavy loads moving and maintaining speed on inclines. Because it's a hydraulic roller design, you can expect improved durability and less friction compared to flat tappet cams, contributing to a longer lifespan for your engine's valvetrain.

This camshaft fits a range of Chevrolet and GMC trucks and vans from the mid-to-late 90s, including models like the 1996-1999 Chevrolet C2500 Suburban and the 1996-2000 GMC Savana 3500. While it offers significant benefits for towing and general use, please note that this camshaft is not CARB approved and cannot be shipped to California. For optimal performance and longevity, it's always recommended to consult the manufacturer's installation instructions and consider pairing it with appropriate valve springs and pushrods.
