Unlock sharper response and improved airflow for your 2024+ GM 6.6L platform with the Bully Dog Performance Quick Spool Turbo. Engineered as a direct OEM replacement, this light-duty turbo upgrade is designed to enhance drivability while maintaining factory-level reliability and fitment.

Built around a 63mm billet compressor wheel, this turbo delivers improved efficiency and stronger airflow characteristics over stock designs. The billet wheel construction increases durability under load while helping support more responsive boost delivery across the RPM range.

The black powder-coated compressor housing adds corrosion resistance and a clean, performance-focused finish, while OEM-quality internal components ensure long-term reliability under daily driving or towing conditions. Designed for direct OEM fitment, installation is straightforward with no major modifications required.

One of the key improvements is reduced turbo lag, resulting in noticeably quicker throttle response and improved low-end drivability. Whether you’re towing, hauling, or daily driving, the upgraded spool characteristics help the engine feel more immediate and controlled. Enhanced airflow further supports overall efficiency and performance consistency.
