This Is The Turbo You Bolt On And Go

If you're looking for more power without overcomplicating your build, the Stealth STR Turbo is exactly what your 2020–2023 L5P Duramax needs. It’s the perfect step up from stock for daily drivers, tow rigs, and anyone using a box tuner or no tuning at all. Right out of the box, this turbo delivers fast spool-up, solid boost, and crisp throttle response, all while keeping factory drivability intact. There’s no need to dive into custom tuning or supporting mods unless you want to, this turbo was designed to work with what you already have. Whether you're pulling a trailer, climbing a grade, or just want your truck to feel more alive, the STR delivers smooth, usable power throughout the RPM range. It also eliminates surge, which means no jerky throttle when you're lugging or towing under load. Best of all, it’s a brand new unit with zero core charge, built from OEM-quality components that are made to last. This is a straightforward upgrade that brings real performance without the guesswork.

This Turbo Uses Smart Design To Get Big Results

The Stealth STR may look stock on the outside, but it’s engineered with upgraded internals that take performance far beyond factory levels. At the heart of this turbo is an 11-blade billet compressor wheel that pushes 70 lbs per minute of air, a noticeable jump from the stock turbo’s 60 lbs per minute. That extra airflow translates to lower EGTs, improved towing power, and more top-end boost while still being safe for emissions-equipped trucks. It holds up under heavy load thanks to lightweight, high-strength materials and a wide efficiency range that minimizes heat and stress during operation. The STR is designed by experienced tuners who understand the balance between responsiveness and reliability, making it ideal for trucks that see daily use and heavy hauling. Surge has been completely eliminated, even when lugging in high gear or towing uphill. It works with factory emissions and standard tuning setups, including plug-and-play box tuners. With no core charge and brand new electronics, it's ready to install and built to perform.
