Smeding Diesel VGT for 04.5-10 6.6L Duramax

The Smeding Diesel VGT turbocharger is a drop-in replacement compatible with 2004.5-2010 6.6L Duramax diesel engines. 

This turbocharger is available in three sizes: 

1. **Cast 61mm** (factory spec) - Ideal for those seeking improved reliability while maintaining factory-level performance. 

2. **Billet 61mm** - A great choice for those looking to take their performance up a notch. The billet wheel is lighter than the factory cast version, resulting in faster spool-up and increased airflow for greater power output. 

3. **Billet 63mm** - This unit can support up to 650-700 horsepower! The design of this billet wheel ensures the fastest spool-up possible, along with significant performance gains. 

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