BBF FE Shaft Rocker Kit 1.75 Ratio

The BBF FE Shaft Rocker Kit 1.75 Ratio by PRW Industries is designed for big-block Ford and FE-series engine builders who require reliable valve actuation with optimized mechanical advantage. This rocker assembly is ideal for high-performance applications where the rocker arm ratio significantly influences valve lift, duration, and overall engine responsiveness.

The 1.75 rocker ratio effectively multiplies camshaft lift, providing enhanced valve lift and quicker opening rates compared to stock 1.6 ratios. This results in improved airflow, better cylinder filling, and more efficient exhaust evacuation. PRW's shaft rocker design ensures even load distribution across the shaft, minimizing flex and enhancing valvetrain stability under load, which is crucial for high-performance setups.

This rocker kit is perfect for BBF and FE block owners looking to upgrade from factory rockers or switch to a higher-ratio setup for increased performance. Proper installation requires verification of pushrod geometry, rocker arm clearance checks, and valvetrain preload adjustments to ensure optimal sealing and prevent valve float.
