This is a completely new replacement turbo actuator that fits the 2007-2024 6.7 Dodge Cummins and medium duty applications. This is not a reman or a rebuild of an existing unit. With the Variable Geometry Technology (VGT) turbocharger in the '07.5-'21 Ram Turbo Diesel trucks, everything changed when it came to servicing it. To work on it you needed training, expensive tools and you couldn't test the actuator, so as a DIY-er truck owner you were left with replacing the turbo which is expensive. If you have a code that starts with P226 you likely have stuck vanes, and this will not fix the issue. We recommend replacing the entire assembly if you have those codes.City Diesel worked to fix this. Step one was to develop an actuator tester that anyone could use. Shortly after they released it, more affordable rebuilt turbochargers started showing up. However, there was still a problem because the actuator has to be calibrated to the turbocharger and you were not able to simply replace an actuator. This means you either have to pay a fee to get the actuator calibrated at a shop that has the correct equipment (average price $200) or buy the entire turbocharger even if the actuator was the ..
