KC Turbos has had a lot of requests to bring the magic from their KC 6.0L Powerstroke turbos over to the Duramax world. They have answered those requests with the 100% Drop-In KC Stage 3 68mm/74mm Turbocharger that has been fitted with a 10-blade turbine wheel to help decrease EGT's while increasing your top-end performance. The upgraded .72ar race compressor cover with a drilled hole surge ring will maximize airflow. It also utilizes features such as new high-flow vanes, an upgraded 360 thrust bearing, and a new VGT solenoid. This turbo will clean up your fuel and give you the power and performance that you have been longing for out of your Duramax!

The Stage 3 68mm/74mm turbo is a no modification required, drop-in turbo for your 6.6L Duramax. If you are wanting to be able to daily drive your truck during the week and race in competitions on the weekend, then this turbo is meant for you. This turbocharger is better suited for making power rather than towing heavy loads.
