Description

The FAST 301439 is a replacement magnet designed for use with FAST XFI Driveshaft Speed Sensor Kits (part numbers 301436 and 301437). This magnet accurately measures driveshaft speed for your traction control unit. When the magnet passes the pickup, it sends a signal to the XFI unit, which calculates driveshaft RPM and acceleration. This provides more accurate data than engine RPM alone. It is perfect for drag race applications, offering an MPH reading and potential MPG calculations with user-input tire size.
