2004.5-2005 Duramax 10 Blade Turbine Wheel w/ Extreme 360 Rebuild Kit (300586)

Transform the sound and performance of your LLY with the ultimate turbine upgrade. This balanced drop-in 10-blade wheel replaces the restrictive factory 13-blade unit, allowing your Duramax to breathe easier at high RPMs while producing the aggressive, high-pitched whistle usually reserved for the early Powerstroke turbos. It’s a must-have for DIY builders looking to decrease backpressure and improve overall thermal efficiency. This package features the Extreme 360 Rebuild Kit option, providing a comprehensive overhaul for those who demand maximum durability from their Duramax. By combining the high-flow 10-blade turbine with a heavy-duty 360-degree thrust bearing from KC Turbos, this kit delivers superior oiling and longevity compared to the factory design, making it the definitive choice for high-performance builds or heavy-towing applications.
