Wehrli 17-23 L5P 6.6L Duramax/19-23 L5D 6.6L Duramax High Flow Turbo Pedestal Kit

The WCFab High Flow Turbo Pedestal Kit for 2017-2023 Chevrolet Silverado or GMC 2500/3500 HD and 2019-2023 L5D equipped Medium Duty trucks equipped with the 6.6L Duramax Diesel offers increased wall thickness and part structure to eliminate cracking and warping commonly found in OEM pedestals. Over the past several years, we have seen more failures of the OEM pedestal. The greatest weak point is the thin wall, especially on trucks with upgraded turbos and high-performance tuning. This turbo pedestal is designed, tested, cast, and machined in the USA! Truly port matched to the gaskets and hardware. Avoid a cracked, warped, or even melted pedestal by upgrading to WCFab's thicker stainless steel pedestal. NOTE: Does not fit 2024+ models. 2024+ version coming soon!
