Specs At A Glance

Good To Know

Q: Will this sensor work on a 2017 Polaris GEM E6? A: This sensor is specified for 2014-2016 models; later years may use a different part number, so confirm by VIN before purchasing.

Q: Can a faulty speed sensor cause the vehicle to shut down? A: Yes, the controller may limit speed or enter limp mode if the sensor signal is lost or erratic to prevent unsafe operation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
