The Cutting Edge Stealth STR takes stock turbo replacement to the next level. Meticulously designed and tested to outperform your stock turbocharger in all aspects. It is proven to lower EGTs in nearly all towing scenarios, increase boost for guys with mild tunes, and demonstrates identical to stock spool-up in testing.

You'll love the unique Stealth sound almost as much as the added performance. This turbo is a direct replacement, for your 2011, 2012, 2013, 2014, 2015, or 2016, 6.6L LML Duramax turbocharger and pairs best with our Stage 2 Intake Kits, High Flow Bundles, and Emissions Compliant Performance Tuning.

The unique advantage of having tuning experts work on this turbocharger design can’t be understated. DuramaxTuner’s experience with the particulars of how the LML Duramax platform responds to tuning adjustments and airflow changes was a crucial component in building the perfect turbo upgrade.

This turbo is a great fit if you...

  • Have reliability and performance as your top priorities
  • Want immediate response and great daily drivability
  • Have a Box Tuner or Custom Tuning installed on your truck
  • Want to make somewhere in the range of 600rwhp
  • Tow with your truck often
  • Have a completely stock truck (this turbo does not require tuning)
  • Need a new replacement turbo for your LML Duramax
