COMP Cams Camshaft Kit LS1 XEr273HR-14

If you're looking to build a high-RPM street or strip LS engine, this COMP Cams XFI XE-R camshaft kit is a solid option. It's designed to give you improved performance, especially at higher engine speeds, thanks to its XE-R lobe profiles. This kit is a comprehensive package, meaning you get everything you need to get the job done right, all from one box.

Inside this kit, you'll find the camshaft itself, along with a full set of hydraulic roller lifters, valve springs, retainers, and valve locks. COMP Cams also includes valve stem seals, a timing chain set, and even assembly lube to make sure your installation goes smoothly. This attention to detail means you're not left scrambling for essential components. The XE-R lobes are known for their aggressive ramp rates, which help to open the valves quickly and keep them open longer, contributing to that sought-after high-RPM power band. Keep in mind that installing a camshaft like this will require custom tuning to optimize your engine's performance and ensure it runs correctly with the new valvetrain specifications.

This kit is designed to fit a wide range of GM LS engines, including popular displacements like 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L found in vehicles such as the Chevrolet Camaro, Corvette, and Silverado trucks. It's a complete solution for enthusiasts aiming for a noticeable increase in their engine's power output, particularly when pushing it hard on the street or at the track.
