The Smeding Diesel VGT for 11-16 6.6L Duramax is a drop-in replacement turbocharger for 2011-2016 Duramax diesels.

This unit will come in 3 sizes; a cast 61mm (factory spec) for those who are looking for better reliability but factory performance. Next is the billet 61mm. This unit will be for those who are looking for the next step up. Our billet wheel is lighter than the factory cast, so it will provide a faster spool up and with our design, will produce more air for bigger power! And last is the billet 63mm. This unit is capable of 650-700hp! This billet wheel will provide the fastest spool up possible while still providing great performance gains! 

Whether you're towing, daily driving, or want to have fun. this is the perfect VGT for your Duramax.
