WHAT MAKES A SCREAMER?
Performance You Can Depend On
The Screamer isn't just another turbo—it's the smarter upgrade for the diesel owner who needs more from their truck every single day. We designed it to deliver a perfect balance of responsive power, improved efficiency, and OEM-level reliability. It's the robust, powerful, and dependable heart your truck deserves.
The core benefit of the Screamer is its ability to dramatically increase airflow to your engine. A better-breathing engine is a more efficient engine. This leads to more complete combustion, helping your truck make the most of every drop of fuel while producing consistent power across the RPM range.
The Screamer delivers a healthy and usable increase in horsepower and torque right where you need it. Forget about turbo lag—you'll get the responsive power to merge, pass, and tow with confidence, all without compromising the smooth, predictable drivability you count on day-to-day. (Note: To unlock the turbo's full potential, a performance tune is recommended.)
By moving more air with greater efficiency, the Screamer helps your engine run cooler. Lowering your Exhaust Gas Temperatures (EGTs) is critical for protecting your engine and pistons, especially when towing heavy loads up steep grades. You can pull with confidence knowing your engine is safer.
At the heart of every Screamer is a CNC-machined billet compressor wheel. It's significantly stronger and lighter than the stock cast wheel, allowing for a more aggressive blade design. This means faster spool-up, quicker throttle response, and superior durability under high boost.
We engineered the Screamer to be a hassle-free, bolt-in replacement. It uses your factory mounting points, plumbing, and connections for a clean installation without the need for custom fabrication, cutting, or welding.
Performance means nothing if you can't rely on it. Every Screamer rotating assembly is subjected to a multi-stage, high-speed VSR (Vibration Sorting Rig) balancing process. This eliminates internal vibrations, ensuring a long, quiet, and durable service life that meets or exceeds OEM standards.
