COMP Cams Camshaft Kit LS1 XR273HR-12

If you're looking to get more power out of your GM LS engine, especially at higher RPMs for street and strip use, this COMP Cams XR273HR-12 camshaft kit is a solid option. This kit is designed to work with a wide range of LS engines, including those found in vehicles like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado. It's a hydraulic roller camshaft, which means it's built for performance and longevity without the need for frequent adjustments.

This isn't just a camshaft; it's a complete package to get your engine breathing better. Inside this kit, you'll find the camshaft itself, along with hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure your valvetrain stays perfectly synchronized. COMP Cams also includes assembly lube and decals to help with the installation process. For this camshaft to perform optimally, you'll need an engine programmer to adjust the fuel and timing maps to match the new cam profile. It's also designed to work well with higher rocker arm ratios, which can further enhance airflow and power output.

When installing this kit, remember that it's intended for performance applications and requires careful attention to detail during setup. It's a significant upgrade that changes how your engine performs, particularly in the upper RPM range. Make sure to follow the included instructions closely for the best results and to ensure proper break-in of the new components.
