LB7 Stealth Turbo
2001-2004, Duramax Turbo Upgrade
The LB7 Stealth Mach 1 and Mach 2 turbochargers are upgraded, drop-in, replacement turbos for the 2001-2004, LB7 Duramax turbo. They are designed to bolt in and require nothing other than removing the factory turbo and dropping this one in it’s place. These turbos feature a custom profile, billet compressor wheels perfectly mapped to a modified compressor cover and an upgraded high-flow turbine inside the stock IHI appearing housing.
Why do people upgrade their turbo?
- Increased Peak Power and Torque
- Improved Towing Performance
- EGT Control
- Repair/Replacement of failed Stock Turbo
We currently offer 2 options for the LB7 Stealth Series turbo. You can select either a Mach 1 or Mach 2 variants. Mach 1 and Mach 2 refers to the size of the compressor wheel used in the final assembly of your turbocharger. Mach 1 turbo's receive a 64mm compressor wheel while Mach 2 variants receive a 67mm compressor wheel. While it is tempting to jump on and purchase the larger compressor wheel just because it is bigger, we suggest doing some research first. Here are a few articles and videos so you can become a well informed shopper.
