BBC Alm Roller Rocker Arm Set 1.7 Ratio

The BBC Alm Roller Rocker Arm Set 1.7 Ratio is designed for big-block Chevrolet engine builders who demand high-performance valvetrain components. This full roller rocker arm assembly is ideal for engines with aggressive camshafts and high RPM builds, ensuring reliable valve actuation and durability in demanding applications.

Constructed with full roller technology, these rocker arms significantly reduce friction compared to traditional stamped steel rockers, allowing for improved horsepower and valve control. The 1.7:1 ratio enhances valve lift, meaning a cam rated at 0.500 inches lift effectively produces 0.850 inches of lift at the valve, which is crucial for maximizing airflow in high-revving big-block engines.

This rocker arm set is particularly beneficial for BBC platforms ranging from 396 to 502 cubic inches, especially those utilizing 1.6 or higher ratio cams. The installation of these roller rockers is a straightforward upgrade that can enhance performance for street, performance, and racing applications alike.
