What you get is a simple upgrade that protects your investment and keeps your truck performing the way it should.\u003c\/p\u003e\n\u003ch4\u003eEngineered Airflow And Structural Strength That Outperforms Stock Design\u003c\/h4\u003e\n\u003cp\u003eThis high flow turbo pedestal is carefully engineered to improve both airflow and long term durability across 2017-2023 GM 2500HD and 3500HD trucks with the 6.6L Duramax. The internal passages are enlarged and fully port matched at the up pipes and turbo inlet, allowing for a measured 12.7 percent increase in flow over the OEM design. This improvement helps reduce restriction in the exhaust path, which supports better turbo efficiency and more consistent performance under load. Furthermore, the increased material thickness throughout the casting strengthens the entire structure, addressing the common failure points found in factory pedestals. The use of formed threads adds another layer of durability, creating stronger and cleaner threads that resist wear over time. Precision casting and machining in the USA ensures proper fitment and alignment during installation.
