COMP Cams Camshaft Kit LS1 XR281HR-12

This COMP Cams XR281HR-12 camshaft kit is built around a hydraulic roller camshaft featuring a 228/230 degree intake/exhaust duration. This specific grind is designed for high-RPM street and strip use, and it's a popular choice for LS Gen III and IV engines, especially when paired with a FAST LSX intake manifold. Because it changes the engine's breathing characteristics, you'll need a programmer to adjust the fuel and ignition timing for optimal performance and drivability.

When you choose this K-Kit, you're getting a comprehensive package designed to make your engine build smoother. It includes the camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. You'll also find a timing chain set to ensure your valvetrain stays synchronized, along with assembly lube and instructions to guide you through the installation. This kit is intended for a wide range of GM LS engines, including displacements from 4.8L up to 7.0L, covering popular applications like the LS1, LS2, LS3, LS6, and LS7 found in everything from Corvettes to trucks.

This camshaft kit is a significant upgrade for those looking to extract more power from their LS engine, particularly at higher RPMs. While it's designed for street and strip performance, remember that it's not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and ensure your engine's computer is reprogrammed to take full advantage of the camshaft's capabilities.
