COMP Cams Rocker Arms348/409 Chevy 1.7

This is a set of COMP Cams Ultra Pro Magnum rocker arms, specifically designed for Chevrolet 348 and 409 engines found in models like your 1959-1961 Chevrolet Kingswood. These rocker arms are a key part of your engine's valvetrain, controlling the opening and closing of the intake and exhaust valves. The 1.7 ratio means that for every amount the pushrod moves, the valve will open slightly more, which can help improve airflow and engine performance.

Built with a strong steel construction, these rocker arms are made to handle the demands of performance engines. They feature a 3/8" stud diameter, ensuring a solid connection to your cylinder heads. This set includes 12 rocker arms, providing enough for a complete engine rebuild or upgrade. COMP Cams is a well-known name in performance engine parts, and these Ultra Pro Magnum rockers are a popular choice for those looking to get more out of their classic Chevy V8.
