MSD Ignition – Crank Trigger Kit; Big Block Ford (Part No.8644)

Crank Trigger Kit; Big Block Ford

from

$538.99
For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD flying magnet crank trigger system does exactly that by using magnets embedded in an aluminum wheel. The MSD flying magnet crank trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This flying magnet design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each flying magnet crank trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver’s side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The adjustable bracket provides a wide range of timing adjustment and spacers are included. These systems will trigger MSD 6, 7, 8 and 10 series ignitions and all MSD timing accessories.

Product Features:
  • Absolutely the most accurate way to trigger the ignition
  • The non-magnetic pickup cannot be false triggered.
  • Powerful magnets are embedded in a billet aluminum trigger wheel.
  • Incl. brackets/mounting hardware to fit a variety of engines
