COMP Cams Camshaft LS1 285Lr HR-113

COMP Cams is well-known for making performance valvetrain components that help engines breathe better and make more power. This specific camshaft, the LS1 285Lr HR-113, is designed to give your GM LS engine a serious boost in performance, especially from the mid-range all the way up to high RPMs. It's built for LS engines that use cathedral port cylinder heads, which are common on many popular GM V8s.

This is a hydraulic roller camshaft, meaning it uses roller lifters to reduce friction and allow for more aggressive cam profiles. The grind number, 235/243, refers to the duration of the intake and exhaust valves opening, indicating a profile that prioritizes strong torque and horsepower gains in the upper half of the RPM band. This camshaft is a great choice if you're looking to significantly improve the power output of your LS-powered vehicle, whether it's a performance car like a Camaro or Corvette, or a truck like a Silverado or Tahoe. It's designed to work with engines displacing 4.8L up to 7.0L, including popular variants like the LS1, LS2, LS3, LS6, and LS7.

When installing a camshaft like this, it's important to ensure you have all the necessary supporting components. This typically includes new valve springs, pushrods, and potentially timing sets, all chosen to match the camshaft's specifications for optimal performance and reliability. Always refer to the manufacturer's installation instructions for the most accurate guidance on what else you might need and the proper procedure.
