When replacing the factory turbo in your 2007.5-2022 6.7L Cummins truck, sometimes it is necessary to replace the turbine shaft speed sensor. We have seen in some cases this sensor is not included with new turbos or individuals break or damage this sensor when attempting to remove it. This sensor from Fleece is a direct replacement for all Holset turbos found on trucks from 2007.5-2022. This sensor will include the o-ring seal that is necessary for a proper fit.
