If you?re running a crank trigger system with the magnets installed in the trigger wheel, the FAST Non-Magnetic Crank Trigger Pickup is a more accurate, highly reliable replacement sensor. It is designed to replace a common non-magnetic pickup with a ?"-16 UNF threaded housing. The FAST sensor produces the most precise signal from cranking through redline RPM and is accurate to within ? 0.1?! There is also a useful LED built-in that is extremely helpful when setting up the static timing before firing up the engine.
