The MSD 86403 Crank Trigger Kit is a high-performance ignition solution designed for race applications and serious street performance use. This kit is specifically engineered for small block Chevrolet engines and features a heavy-duty crank trigger with superior electrical contact for reliable and consistent ignition pulses.
The heart of the system is an all-new, eight-lobe crank trigger housing constructed from military-specification aluminum alloy. This premium housing is designed to withstand the extreme heat and vibration of high-performance engines, ensuring long-lasting durability. It also features a tapered design to ensure proper trigger alignment for highly accurate ignition timing.
The kit includes a set of high-tension, ceramic crank trigger wheels designed to provide optimal triggering with a small-block Chevrolet crankshaft. The ceramic material is a proven choice for its high durability and ability to maintain consistent shape under extreme conditions. The trigger wheels are also precisely balanced to minimize balancing requirements and reduce unnecessary engine vibrations.
The MSD 86403 Crank Trigger Kit also includes a high-tech, eight-lobe camshaft sensor, designed to ensure accurate RPM measurement for engine management systems that require digital trigger input. The sensor features a rugged design and is encapsulated in a durable epoxy coating for superior protection against engine heat and oils.
This kit is easy to install on most small block Chevrolet applications with no modifications required. The trigger housing comes with all necessary mounting hardware, while the trigger wheels are held in place with a slip-on design. The camshaft sensor bolts directly in place of the factory sensor for a straightforward installation.
In summary, the MSD 86403 Crank Trigger Kit is a premium ignition solution that delivers superior performance, reliability, and durability for high-performance small block Chevrolet applications. Its proven design, combined with high-quality materials and robust construction, helps ensure consistent ignition timing and maximum engine performance.

The MSD Flying Magnet Crank Reluctor system does exactly that by using four magnets embedded in an aluminum wheel. Most crank reluctor have a wheel, with steel studs sticking out, bolted to the harmonic balance. The MSD Flying Magnet Crank Reluctor uses four magnets secured in the aluminum reluctor wheel that pass by a stationary non-magnetic pick-up to ignition. Buyer pays return shipping.
Absolutely the most accurate way to trigger ignition. These systems will reluctor MSD 6, 7, and 8 Series Ignitions all Timing Accessories.;. 86403 MSD Crank Reluctor Wheel Kit - Flying Magnet SBF Windsor: 289/302/351W Use with 6/7/8 Series Ignition Black: For a long time, racers have known that one of the best things to do an engine improve performance is stabilize ignition timing. This flying magnet design produces accurate reluctor signals and the non-magnetic pick-up cannot be falsely reluctor ed.
Powerful magnets are embedded in a billet aluminum trigger wheel. This pick-up can be reluctor ed by other bolts, debris, or even vibrations which will cause a loss of power engine damage. Kits feature special brackets and mounting hardware for a variety of engines. As the crankshaft turns, studs pass by a stationary magnetic pick-up, refactoring ignition.
Each Flying Magnet Crank Reluctor includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either passenger side or drivers of engine the SB Chrysler and Ford brackets mount only one. Although similar in appearance to other crank reluctor, the MSD Flying Magnet design works on a different principle. A signature is required on all UPS orders over $750. Spacers are included so you can mount the bracket on engines with standard motor mounts or a .25 plate.
The non-magnetic pickup cannot be false triggered.
