COMP Cams Camshaft LS1 XR265HR-14

If you're looking to get more torque and a strong mid-range punch from your GM LS engine, this COMP Cams XR265HR-14 camshaft is a solid option. It's designed to work with a wide range of LS displacements, from 4.8L all the way up to 7.0L, including popular variants like the LS1, LS2, LS3, and LS6. This camshaft is a popular choice for builds that prioritize street performance and drivability, aiming for that sweet spot where you feel the power increase most often.

This is a hydraulic roller camshaft, meaning it uses roller lifters to reduce friction and wear compared to flat tappet designs. The grind number, XR265HR-14, tells you a bit about its characteristics: it's a well-regarded performance grind that balances improved power output with reasonable street manners. You can expect a noticeable improvement in acceleration and responsiveness, especially in the RPM range where you'll be doing most of your driving. It's important to note that this camshaft is specific to the LS GEN III and GEN IV engine families and requires appropriate valve springs and potentially other supporting modifications for optimal performance and reliability.

When installing a camshaft like this, it's always a good idea to consult the manufacturer's detailed installation instructions. This ensures you have the correct valve springs, pushrods, and any other necessary components to match the camshaft's specifications. Proper installation is key to unlocking the full potential of this camshaft and ensuring it performs as expected for years to come.
