Introducing the next generation of Holley EFI Dual Sync Distributors, the new design features an improved shutter wheel, high-quality dual Hall Effect sensors, and an MSD cap and rotor! While these distributors are designed to be used primarily in sequentially injected installations, you can easily use them as a crank trigger for TBI system also. The precision machined shutter wheel design ensures accurate timing, even at very high engine speeds. The Gen 2 Dual Sync also included a QPQ coated shutter wheel for superior corrosion resistance, and the wheel has been pinned and welded to the shaft for increased reliability.
