BBM Shaft Rocker Arm Kit - 1.5/1.5 Ratio

The BBM Shaft Rocker Arm Kit - 1.5/1.5 Ratio is a precision valvetrain component designed for street and mild performance applications where mechanical advantage and durability are essential. This rocker arm assembly is specifically engineered for small-block Chevrolet engines, providing an upgrade path for builders looking to enhance valve control without extreme lift requirements.

Manufactured from high-strength alloy steel, this kit features precision machining to maintain tight tolerances, which minimizes valvetrain noise and variability. The shaft-mounted design offers superior stability compared to traditional rocker pedestals, evenly distributing loads and reducing the risk of fatigue failure during sustained high-RPM operation. The 1.5/1.5 ratio provides equal mechanical advantage on both intake and exhaust sides, simplifying tuning and ensuring balanced airflow dynamics.

Ideal for builders upgrading small-block Chevrolet engines, this rocker arm kit is perfect for those rebuilding classic muscle cars or enhancing daily drivers. Its design delivers reliable and consistent valve actuation, making it a valuable addition for anyone assembling a naturally aspirated performance engine.
