Comp Cams Harley-Davidson Thumpr Front & Rear Vthunder Camshaft Set - .569in/.569in - 243/257

This is the COMP Cams Thumpr camshaft set, designed for Harley-Davidson V-Twin engines. It includes both the front and rear camshafts, featuring a .569 inch lift for both with a 243 degree intake and 257 degree exhaust duration. This set is built to give your Harley that signature Thumpr idle sound and an improved powerband, especially in the mid-range where you use it most on the street.

COMP Cams is known for making well-built valvetrain components, and this set is no exception. The camshafts are ground from quality steel and are designed to work as a matched set for optimal performance and reliability. When installing these, you'll want to ensure your valve springs are up to the task, as the .569 lift requires a spring that can handle it. It’s a popular choice for riders looking to get more out of their V-Twin without going into a full engine build.

Keep in mind that this camshaft set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and any additional components you might need, such as new lifters or pushrods, to ensure a smooth and effective upgrade.
