COMP Cams Camshaft Kit CS XR280HR-11

COMP Cams is well-known for making performance camshafts and valvetrain components. This Xtreme 4x4 hydraulic roller camshaft kit is designed for Small Block Chevrolet engines from 1987 and newer that originally came with a factory roller camshaft. It's built to give you good top-end power, making it a solid choice for builds focused on higher RPM performance.

This kit includes the CS XR280HR-11 camshaft, a set of hydraulic roller lifters, a timing chain set, and assembly lube to help ensure a smooth installation. The camshaft itself has a 230-degree intake duration and a 234-degree exhaust duration at .050 inch lift, with a 111-degree lobe separation angle. This profile is intended to work best with headers, lower rear-end gears, and a torque converter rated for 2500 RPM or higher, which helps you take full advantage of the improved airflow and powerband this cam offers. It fits a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and C1500 Suburban from the late 80s and 90s.

To get the most out of this camshaft kit, you'll want to ensure your exhaust system is upgraded with headers, and consider changing your rear axle gears and torque converter to match the cam's performance characteristics. This kit is a significant upgrade for your engine's breathing and power potential.
