The Industrial Injection 422405 PhatShaft 66 Turbo Kit is built to perform and will dramatically increase performance and reliability in your 2001-2004 GM 6.6L Duramax LB7. The PhatShaft turbo kit utilizes the legendary Industrial Injection Silver Series Turbo. The Silver 66 is perfect for street performance trucks that tow light loads.
