About This Remanufactured Turbocharger — GM Duramax 6.6L (2017–2019) The 2017–2019 GM Duramax 6.6L L5P is the most sophisticated Duramax engine ever produced, delivering 445 horsepower and 910 lb-ft of torque from the factory. It uses a single Garrett variable geometry turbocharger with an electronic actuator — a significant departure from the previous fixed-geometry Duramax turbos. Part number 12723305 identifies the correct exchange unit for this application. When the L5P turbocharger develops bearing wear or vane actuation issues, the truck goes into reduced power mode and the check engine light illuminates with boost-related codes. This remanufactured unit is rebuilt at PT Turbo in San Bernardino, California, to factory specification with all wear components replaced and the CHRA balanced before shipping. Remanufacturing Includes Complete teardown, cleaning, and inspection New journal bearings, thrust bearing, and seals throughout VGT nozzle ring and vane assembly inspection High-speed CHRA balancing Electronic actuator testing and calibration check Important Fitment Note This part number is specific to the 2017–2019 L5P Duramax. It does not fit the LML (2011–2016) or LBZ/LMM generations, which use different turbocharger designs. Confirm your model year and existing part number before ordering. If you are uncertain, PT Turbo can verify fitment. We have been rebuilding Duramax turbochargers across all generations since the platform launched and ship nationwide from San Bernardino, CA.
