Magnum Rocker Shafts - SBM

The Magnum Rocker Shafts for Small Block Mopar by COMP CAMS are designed for engine builders and performance enthusiasts looking to enhance their small-block Mopar engines. These rocker shafts serve as a vital upgrade, particularly for those modifying cylinder heads and aiming for high-RPM performance. They are suitable for various small-block Mopar variants, including the 340 and 360 engines.

Engineered to replace stock components, these rocker shafts help eliminate bottlenecks in high-RPM applications. Their precision manufacturing and superior material composition reduce rocker arm deflection under load, ensuring consistent valve lift throughout the RPM range. Additionally, the optimized oilway design minimizes oil starvation at the rocker arm pivot points, which is crucial for maintaining performance under high-lift camshaft conditions.

These rocker shafts are ideal for builders who are installing performance camshafts and upgraded valve springs, allowing small-block Mopar engines to exceed stock output limits. Proper installation is essential for achieving the desired performance benefits, and these components are specifically designed to work with COMP CAMS rocker arms and small-block Mopar heads.
