Repl. Distributor Rotor for Pro-Flo 4 Distr.

The Edelbrock Replacement Distributor Rotor for Pro-Flo 4 Distributor is an essential wear item for any engine builder, hot rodder, or tuner running Edelbrock's modern Pro-Flo 4 ignition system. This rotor acts as the critical switching component inside your distributor cap, directing high-voltage spark pulses to each cylinder in precise firing order. Whether you're maintaining a daily driver, rebuilding a classic muscle car, or fine-tuning a high-performance street engine, a fresh rotor ensures clean spark delivery and eliminates misfires caused by worn or degraded contact surfaces.

Designed specifically for the Pro-Flo 4 system, this rotor features Edelbrock's precision engineering to handle the demands of both stock and modified engines. The rotor's contact surfaces are engineered to minimize electrical resistance and resist arcing, ensuring reliable spark transfer across a wide RPM range. Unlike inferior aftermarket or worn OEM rotors, Edelbrock's design maintains consistent spark timing and reduces radio frequency interference—critical factors when running upgraded fuel systems, carburetors, or electronic fuel injection alongside a Pro-Flo 4 distributor. The compact, lightweight construction (0.07 lbs) fits seamlessly within the distributor cap without adding vibration or wear to internal components.

This rotor is ideal for enthusiasts performing scheduled maintenance, troubleshooting ignition issues, or upgrading to a Pro-Flo 4 distributor system on vintage Chevrolet, Ford, Mopar, and other domestic engines. Installation is straightforward—simply remove the old rotor from the distributor shaft and snap the new one in place; no special tools or modification required. For maximum ignition system performance and reliability, pair this rotor with a fresh distributor cap and quality spark plug wires. This is a genuine Edelbrock part (MPN 22734), ensuring compatibility and longevity in any ignition rebuild or engine refresh.
