Built To Handle More Boost And Eliminate Weak Points For Good

If you have spent any time pushing your Duramax harder than stock, you already know the factory turbo pedestal is not built for the long haul. This upgraded high flow pedestal from Wehrli is designed to fix that problem at its core with a much stronger and more durable construction. Built from 316 stainless steel and made right here in the USA, it delivers the kind of reliability you want when you are running higher boost or upgraded turbos. The thicker wall design helps prevent the cracking and warping that commonly shows up on factory units, especially under heat and pressure. Additionally, the reinforced flange adds even more strength where it matters most, so you are not dealing with leaks or failures down the road. The included ARP hardware gives you confidence during installation, knowing everything is built to handle serious load. What you get is a simple upgrade that protects your investment and keeps your truck performing the way it should.

Engineered Airflow And Structural Strength That Outperforms Stock Design

This 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. When everything works together, you end up with a component that not only flows better but also stands up to the demands of high performance diesel applications.
