Take your GM to the next level with our Performance Turbo kits, including options from our exclusive Screamer line designed for serious towing and racing. With enhancements for better flow, power, and efficiency, these turbochargers are the ultimate upgrade for drivers seeking to maximize their vehicle's performance and response on and off the road.

The BD Diesel
Engineering Advantage

Seamless Variable Geometry Integration

Engineered to drop directly into your truck's factory control system, our GM turbos are fully compatible with your stock vane position sensor and actuator setup. By reducing rotational inertia with a lightweight, precision-engineered compressor wheel, the factory actuator can sweep the vane system more efficiently. This maximizes low-end throttle response and preserves your critical factory exhaust braking functionality without requiring physical modifications to the OEM vane geometry.

High-Flow Turbine & Compressor Engineering

Our GM lineup—including the Screamer series—utilizes custom-profiled wheels designed to reduce backpressure. By optimizing airflow, we lower Exhaust Gas Temperatures (EGTs) and improve throttle response, providing the performance and reliability that stock castings can't match.

VSR High-Speed Precision Balancing

Every GM turbocharger is balanced on a Vibration Sort Rig (VSR) at speeds exceeding 100,000 RPM. This process eliminates the microscopic imbalances that cause premature bearing wear, ensuring your Duramax maintains factory-level harmonics even under high-boost conditions.

Turbo Selection Guide

  1. Match Your Engine RPO Code

    Duramax generations (LB7, LLY, LBZ, LMM, LML, L5P) have distinct turbo footprints. Verify your RPO code to ensure a perfect, "no-mod" drop-in fit for your specific GM year range.

  2. Determine Your Power Requirements

    Decide between a Stock Replacement for OEM reliability or a Screamer upgrade to increase airflow and lower EGTs—essential for Duramax trucks used for heavy towing or performance street use.

  3. The VGT Advantage: Why We Retain Factory Architecture

    We engineer our premium drop-in upgrades strictly around the factory Variable Geometry (VGT) architecture for the 6.0L and 6.7L platforms. While some aftermarket options convert to fixed-geometry setups, retaining the VGT system is the only way to preserve lightning-fast low-end throttle response, prevent sluggish turbo lag, and keep your critical factory exhaust braking fully functional.

  4. Plan for Supporting Modifications

    Consider the "Duramax Ecosystem." High-flow turbos often perform best when paired with a BD High-Flow Intake Manifold (to remove the "horn" restriction) and matched fueling upgrades or performance tuning.

  5. Verify High-Grade Hardware

    Confirm your kit includes Class 8.8+ hardware and multi-layer steel (MLS) gaskets. As you noted with our manifold kits, using high-grade fasteners is essential for a leak-free seal against high thermal expansion.

How Do I Choose Between A Stock Turbo And A Performance Turbo?

Choose a Stock Turbocharger if you want factory-spec functionality with a drop-in replacement. Choose a Performance Turbo Kit if you want stronger airflow, response, and power potential, including Screamer options built for towing and racing use.

What Chevy/GM Applications Are Covered?

Stock Turbochargers: 6.6L L5P/LML 2011-2024, 6.6L LLY/LBZ/LMM/LB7 2001-2010, 6.5L GM-8/GM-5 1996-2000. Performance Turbo Kits: L5P 2017-2024, LML 2011-2016, LLY/LBZ/LMM 2004.5-2010, LB7 2001-2004.

What Is A Screamer Turbo?

The Screamer is a stock-appearing, drop-in performance turbo designed to increase airflow without compromising low end response.

Will A Screamer Turbo Still Drive Well On The Street?

Yes. Screamer turbos are designed to improve airflow while maintaining strong low end response, so drivability stays consistent.

Do I Need Custom Tuning With A Screamer Turbo?

Screamer turbos are designed to work with box tuners, and custom tuning can unlock further gains depending on your build.

I Tow Heavy. What Should I Prioritize When Choosing A Turbo?

Prioritize response, manageable EGTs under load, and the correct application match. If you need more airflow than stock, choose a performance kit designed for serious towing use.
