    Distributors Geared for Racing

    MSD Ignition Crank Trigger distributors are designed for racing engines that use a crankshaft triggered ignition. A low profile lets these distributors fit in tight quarters and still accurately deliver the sparks. Each crank trigger distributor contains a CNC-machined billet aluminum housing and inside the housing, a sealed ball bearing and long sintered bushing, guide a QPQ-coated shaft for accurate spark delivery throughout high rpm. A low profile distributor cap with brass terminals clamps onto the housing and covers the racing rotor. The rotor contains deep vanes to stir up the air; reducing the chance of spark scatter. Since these distributors are for racing applications, bronze gears are supplied. Must be used with an MSD Crank Trigger and MSD 6, 7 or 8-Series Ignition Control
