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

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.

Color: Upgrade-apricot, Size: 16 Inch
Am not disappointed buying this bag it’s spacious all different type of pockets the zippers are so unique the thickness is everything to talk about . I used this for my work bag that I carry 5 days of the week with my uniform,shoes,water bottle,phone,tablet etc and it’s still leaves a lot more space the firmness and sturdiness is 100% ..So comfortable the padding on the back and the shoulder keeps you relaxed. This is value for your money , my coworker are so inlove with my backpack

Very functional and spacious!
Color: Upgrade-apricot, Size: 16 Inch
I wasn’t expecting to love this backpack as much as I do, but wow —it’s everything I wanted and more. The apricot color is soft and pretty without being too “girly,” and the fabric has a nice matte texture that feels durable yet lightweight. It doesn’t have a plasticky smell at all, just a clean, new bag scent right out of the packaging. The compartments are super well thought out. I can fit my 16-inch laptop, chargers, skincare pouch, and even a change of clothes without the bag looking bulky. The back padding is surprisingly comfy, especially during long airport days, and the straps don’t dig into my shoulders. It sits well on my carry-on handle, making it the perfect travel companion. If you’re into functionality and aesthetics, this is it.
