JayCee's Billet Crank Trigger Distributor is crafted from solid 6061t-6 aluminum and anodized for a professional, lasting finish. Featuring two roller bearings and a steel rotor shaft, this distributor offers reliability at high RPMs, with a non-resistor rotor contributing to a powerful ignition spark. Plus, the larger two-piece cap eliminates cross-fire, and its low profile accommodates all over the top headers.
