FAST Sensor Kit Driveshaft Speed-1

This kit from FAST includes a driveshaft speed sensor, two magnets, and a collar designed to fit around a 1.875" diameter pinion yoke. It's built to give your XFI unit precise data on your driveshaft's speed, which is crucial for fine-tuning your traction control system, especially in drag racing applications. By directly measuring the driveshaft's rotation, this sensor provides a more accurate reading than relying solely on engine RPM, helping you get a better handle on your vehicle's performance.

The collar fits snugly around the pinion yoke, and the magnets attached to it pass by the pickup sensor as the driveshaft spins. Each pass generates a signal that the XFI unit interprets to calculate both driveshaft RPM and its acceleration. This advanced data allows for more effective traction management and can even provide an estimated MPH reading if you input your tire size, giving you a clearer picture of your vehicle's performance metrics.
