01-04 Duramax LB7 Stealth 64G2 Turbocharger

01-04 Duramax LB7 Stealth 64G2 Turbocharger




640HP, Drop-In, LB7 Stealth 64G2 

The only stock appearing, liquid cooled, 360-degree thrust drop-in style LB7 turbo on the market today!

The larger turbine assembly allows for lower drive pressure, creating a better balance between boost and drive (exhaust backpressure). This improved balance under heavy load means more efficiency and power at a given boost number, resulting in lower EGTs under heavy load. Overall peak power is also improved, where the LB7 Stealth 64 would normally support 600-610 HP, the LB7 Stealth 64G2 now pushes the envelope to 640HP. You’re not going to find all of these features anywhere else in the aftermarket in a truly stock appearing, bolt-in IHI turbocharger.

LB7 Stealth 64G2 technology takes our LB7 Stealth 64 and improves every element of it – including the sound.

The LB7 Stealth 64G2 is designed to take the stock long block LB7 as far as possible with stock connecting rods – that’s up to 640 rear wheel horsepower.

To set a strong forward trajectory on our turbo program we’ve aggressively brought as much of the development and build processes in house.  Our machinists and builders are enthusiasts who are empowered to look for and actively pursue improvements in design, to hone the product quality at every point in the process.

On the LB7 Stealth 64G2 that means improved tolerances and attention to compressor wheel design. It means sectioning several exhaust housings to ensure consistency in exhaust housing scroll and exducer profile improvements.

Every charger is inspected and QC’d before it ships and backed by our Duramaxtuner warranty.

The LB7 Stealth 64 has been on the market since 2013. The LB7 Stealth 64G2 represents everything we’ve learned – coupled with our in-house manufacturing and quality control – to bring the Stealth 64 to the next level.
