The Bully Dog 56151 is a Stage 1 VGT (Variable Geometry Turbocharger) designed specifically for low-horsepower Cummins big rig engines.

The most critical factor for compatibility is your engine's horsepower rating and the OEM cross-reference number. This turbo is intended for engines in the 400–500 HP range.

Vehicle & Engine Compatibility

This unit is a direct bolt-on replacement for the following Cummins engine series:

• Cummins ISX15 (Years: 2011–2017)

   

• Cummins X15 (Efficiency Series / Low HP models)

   

• Cummins QSX (Industrial/Agriculture variants)

   

OEM Cross-Reference Numbers

If your current turbo matches any of these OEM part numbers, the 56151 is a compatible replacement:

• Primary Reference: 2882111

   

• Additional References: 5502825, 5502825RX, 2881807, 2882004, 2882111RX, 3773562, 3773568, 3773569, 3772586, 3768194, 3767306, 5350506, 5350503.

   

Key Technical Specs

• Pre-Calibrated Actuator: Includes a new electronic actuator that is pre-calibrated, meaning you can "bolt and go" without needing specialized Cummins Insite software for calibration.

   

• Billet Compressor Wheel: 64mm inducer (lighter than stock) for faster spool-up and reduced turbo lag.

   

• No Core Charge: Unlike many OEM replacements, this is usually sold as a 100% new unit with no core return required.

   

Note for High HP Engines: If your truck is rated for over 500 HP (typically 525–625 HP), you likely need the Bully Dog 56150 instead. Installing the 56151 on a high-HP engine may result in restricted top-end performance or "lazy" response.
