BBM Pro-Mag Rocker Arms - Shaft Mnt. 1.5 Ratio

The BBM Pro-Mag Rocker Arms - Shaft Mnt. 1.5 Ratio is a precision engine component designed for performance builders and engine shops seeking enhanced valve train stability and lift multiplication. These rocker arms are suitable for high-revving, high-horsepower applications, making them ideal for a variety of performance vehicles.

The 1.5 ratio configuration amplifies camshaft lift by 50 percent, resulting in greater valve travel and improved cylinder filling. This is critical for engines that require maximum scavenging efficiency and responsiveness. The shaft-mounted design integrates the rocker assembly into a rigid support system, which helps eliminate individual stud deflection and reduces valve train harmonics.

Engine builders and technicians will benefit from the robust construction of these rocker arms, which can withstand the cycling loads associated with high-performance applications. They are designed for reliability and precision, making them a valuable addition to any performance engine build.
