Give your 2011–2016 GM 6.6L Duramax a new level of performance and reliability with the Bully Dog Quick Spool Turbo. Designed as a direct OEM replacement turbocharger for Chevrolet Silverado HD and GMC Sierra HD trucks equipped with the 6.6L Duramax diesel engine, this upgraded unit restores lost performance while improving airflow, boost response, and overall drivability — on tow rigs, work trucks, and daily drivers alike.
It features a precision-crafted 63mm billet compressor wheel that moves air more efficiently and spools faster than a tired factory unit, translating into quicker throttle response and more responsive performance under load. Manufactured with OEM-quality components and engineered for exact fitment, it installs directly in place of the original turbocharger with no modifications or custom fabrication required.
