Product Details

This COMP Cams XFI 266 HR15 camshaft is designed for GM LS Gen III and IV engines, commonly found in vehicles like the Chevrolet Silverado, GMC Sierra, and Cadillac Escalade. It's a hydraulic roller camshaft that aims to deliver notable gains in the mid and upper RPM range, giving your engine a stronger pull when you need it most. This camshaft is specifically ground for displacements ranging from 4.8L up to 7.0L, including popular engines like the 5.3L and 6.0L found in many trucks and SUVs.

The XFI Xtreme Truck grind is built to improve your engine's breathing, especially at higher revolutions. To really unlock its potential, you'll want to pair it with an exhaust upgrade, as the factory exhaust can sometimes hold back the improved airflow. You'll also need a programmer to adjust the engine's computer for the new camshaft's specifications, ensuring optimal performance and drivability. This camshaft is a solid option if you're looking to wake up the power in your LS-powered truck or performance car.

When installing this camshaft, remember that it's designed for hydraulic roller lifters, which are standard on most LS engines. You'll also want to ensure you have the necessary tools and knowledge for camshaft installation, or plan to have a trusted mechanic handle it. Because this part is not CARB approved, it cannot be shipped to California.
