GMC Sierra 2500HD Turbocharger - aFe - BladeRunner GT Series - Gold - `04-`10 is a direct-replacement turbocharger engineered for 2004.5–2010 GM 6.6L Duramax (LLY/LBZ/LMM) Silverado/Sierra 2500HD and 3500HD trucks. It provides an OE-compatible fit with upgraded compressor and turbine hardware designed for improved responsiveness over the stock unit.

The BladeRunner GT Series turbocharger features a gold-anodized 6/12 bladed billet aluminum compressor wheel that is lighter and stronger than the stock cast wheel to help provide quicker spool-up and increased airflow. Key internal dimensions are 65 mm compressor inducer and 98 mm compressor exducer (trim 44), with a 72 mm turbine inducer and 66 mm turbine exducer (trim 84). This turbo is a direct bolt-on replacement that matches OE geometry for reliable connections, requires no additional fueling, and is offered as a stock upgrade with no core charge. The unit is covered by a 2-year warranty and is intended for owners seeking a durable, performance-focused replacement without complicated supporting modifications.
