MSD Engine Crankshaft Position Sensor Magnet

MSD Crankshaft Position Sensor Magnets: Race-Proven Precision Triggering

When accurate ignition timing is the difference between a podium finish and a DNF, the quality of every component in your crank trigger system matters — including the sensor magnet. MSD, a brand synonymous with ignition innovation since 1970, brings the same engineering discipline that powers Top Fuel dragsters and NASCAR entries to its engine crankshaft position sensor magnets.

MSD was the first company in the world to experiment with Multiple Spark Discharge for the ignition system of internal combustion engines in 1970. That pioneering DNA is woven into every component the brand produces. MSD crank trigger kits include precision trigger wheels, sensors, brackets, and installation hardware for crank position sensing and accurate ignition timing on performance and EFI engines. The sensor magnet is a critical piece of this system — it is what the pickup “reads” as the trigger wheel spins, generating the precise voltage signal the ignition box relies on to fire at exactly the right moment.

What Makes MSD’s Crankshaft Position Sensor Magnets Stand Out

MSD’s crankshaft position sensor magnets are engineered specifically around the demands of their Flying Magnet crank trigger architecture. These components are designed with a shielded, non-magnetic pickup format in a 3/8 in. x 1.5 in. profile. The 3/8-diameter pick-ups are used with MSD’s Sprint Car crank trigger systems as well as the professional racing kits from RCD and PSI. This compatibility with industry-standard racing kits makes them a go-to choice for circle track builders and chassis fabricators who need verified, race-legal components.

MSD also offers a Hall Effect variant of the common 3/4-16" thread crank sensor for flying magnet crank triggers. The Hall Effect design provides a crisp, digital-style output signal that is highly resistant to electrical noise — an important advantage in high-EMI racing environments where analog signals can be corrupted by high-output ignition systems and charging equipment. Whether you’re running a traditional magnetic pickup or a Hall Effect setup, MSD has engineered the matching magnet components to deliver a clean, repeatable trigger signal at any RPM.

Part of a Complete MSD Crank Trigger Ecosystem

From lockouts and bushings to sprockets and crank triggers, MSD has all the hardware to optimize ignition timing and performance. Choosing an MSD crankshaft position sensor magnet means you’re selecting a component built to interface seamlessly with MSD’s broader trigger wheel and sensor ecosystem — including wheels sized for Small Block Chevy, Big Block Chevy, LS Gen III/IV, and Chrysler small block and B/RB applications. MSD has gone on to be the ignition of choice of the top professional drivers in NHRA, IHRA, NASCAR, World of Outlaws, DIRT, SCORE, IDBA, and many more.

For racers, restorers, and performance builders who demand consistency from the very first trigger pulse, MSD’s crankshaft position sensor magnets represent the same commitment to precision that has made the brand a legend in motorsports.
