Product Details

If you're looking to get more usable torque and better mileage out of your stock or mildly modified Small Block Chevrolet engine, this COMP Cams Cam & Lifter Kit is a solid choice. Specifically designed for engines with factory roller camshafts from 1987 and newer, this kit, part number CL08-409-8, offers an updated camshaft profile that balances power with efficiency. It's a popular option for vehicles like the Chevrolet Camaro, Corvette, and C1500 Suburban, among many others from 1987 through 1996.

The XR258HR-1 camshaft profile is engineered to provide strong low-end and mid-range torque, making it ideal for everyday driving and towing applications where responsiveness is key. This hydraulic roller design is known for its efficiency and reduced friction compared to flat tappet setups, contributing to both improved performance and potentially better fuel economy. The kit includes everything you need to get started: the camshaft itself, a set of matching lifters, assembly lube to ensure proper break-in, and decals for that finishing touch. COMP Cams is a well-known name in performance engine components, and this kit reflects their experience in creating parts that work well together.

When installing a new camshaft and lifter kit, it's important to follow the manufacturer's instructions carefully, especially regarding the break-in procedure. This kit is designed as a direct replacement for OE roller camshafts, simplifying the installation process for mechanics familiar with these engines. Ensure your engine meets the '87+ GEN 1 Small Block Chevrolet criteria with a factory roller camshaft to confirm compatibility.
