COMP Cams is well-known for its performance camshafts, and this LSR Roots Blower hydraulic roller camshaft is a prime example of their expertise for GM LS engines. This specific grind, the 289Lrb HR-114, is designed to work best in street and strip applications where a Roots-type supercharger is already installed. It's built for GM LS GEN III and IV engines, covering a wide range of displacements from 4.8L up to 7.0L, including popular variants like the LS1, LS2, LS3, LS6, and LS7.

The hydraulic roller design means it's built for durability and consistent performance without the need for frequent adjustment, making it a solid choice for enthusiasts looking to get the most out of their supercharged LS setup. It fits a broad spectrum of vehicles, from performance cars like the Chevrolet Camaro and Corvette to trucks and SUVs such as the Cadillac Escalade and Chevrolet Silverado.

When installing this camshaft, it's important to follow the manufacturer's recommended procedures and ensure you have the correct valve springs and other supporting components to match the camshaft's specifications. This ensures you get the intended performance gains and longevity from your engine build. Please note that this camshaft is not CARB approved and cannot be shipped to California.
