S/S Shaft Mount R/A System - BBM 1.5 Ratio

The S/S Shaft Mount R/A System - BBM 1.5 Ratio is a precision rocker arm assembly designed for high-performance Mopar B and RB-series engine platforms. This system is ideal for builders and enthusiasts seeking reliable valve train performance in various applications, including competition and street use.

Featuring a shaft-mounted roller tip design, this assembly enhances valve actuation geometry and reduces friction compared to traditional stud-mounted systems. The 1.50 rocker ratio increases the effective lift of the camshaft, allowing for improved airflow without the need for excessively long cam durations. Constructed from durable steel and finished in natural (unplated) form, it ensures stability and precise alignment at high RPM.

Engine builders, restoration shops, and performance enthusiasts will benefit from this assembly when rebuilding or upgrading Mopar B-block and RB-block engines. The shaft-mount design guarantees consistent rocker geometry across the valve train, which is essential for maintaining accurate valve timing.
