FAST's XDi Pro Race Distributors are the only choice when it comes to high end circle track racing where engines demand the most accurate timing and reliable trigger signals. These distributors are engineered from the inside-out to deliver the precise control and superspeedway endurance race teams require. Incorporated are dual optical trigger pickups for the most reliable and accurate trigger signal. The signal from these optical pickups is then synthesized into a common magnetic trigger signal that can be used with most racing ignitions such as the E6 series. A stainless steel trigger wheel allows for modifications so a custom cylinder-to-cylinder timing order could be created. wiring is routed into Weatherpak connectors that will plug into common wiring harnesses for sealed and locked connections. For high RPM endurance, the stainless steel distributor shaft rides in a ball bearing guide with two seals for optimum oil and vacuum control. Each distributor is supplied with a bolt-down distributor cap, wire retainer and rotor.
