Building the line of Stealth Turbos meant designing a turbo that's safe to tow with, fun to drive every day and a class leading competitor. If you think street-able, clean, stealthy power is cool, then this is the turbo for you.

Duramax Tuner's custom-built Mach 2 (67mm) compressor wheel is specifically designed to maximize peak power while maintaining a wide, useable powerband. To fit the monster compressor wheel, they developed a unique, OEM appearing, anti-surge ring, which nestles in the factory compressor cover. Matching the class-leading compressor performance meant updating the center section which is fitted with a 360-degree thrust bearing to increase reliability under heavy load transitions. The wastegate was even updated to make sure you have the most amount of power and the quickest spool-up.

With the compressor side and center section put together, a turbine wheel and exhaust housing upgrades had to be made. The LB7 Stealth Mach 2 (67) features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive pressure and allows for serious power production even at high RPM where the IHI typically falters. This monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure, which not only helps make more power but also manages EGT's (Exhaust Gas Temperature) under heavy load.

TURBO SPECIFICATIONS:
  • Compressor Wheel Inducer: 67mm
  • Compressor Inducer Bore: 68mm
  • Compressor Wheel Blade Count: 11 Blade
  • Turbine Wheel Exducer: 71mm
  • Turbine Wheel Inducer: 77mm

IMPORTANT NOTE: This turbo will not replace the turbo on a CA emissions truck that was equipped with EGR. Only for fitment on Federal emissions trucks that were not equipped with EGR.

Triggers rocasea
It isn't as greasy feeling as I thought it might be, and it smells good and feels nice and creamy. I have slight rocasea, and the product made my skin turn red and burn a little. I'm not sure whether I should continue using it. It might be great for people without rocasea.

Smooth skin!
This product is so smooth and the scent is very faint of honey! My skin feels softer now and it doesn’t leave my eczema/psoriasis feeling more itchy after applying. It has a cooling effect.

Middle of the jar was emptied
When I swiped my finger across the top layer to scoop out enough to put on my face, I notice a deep void in the middle of the jar. The middle of the jar was missing the whipped tallow.
