2017-2023 Duramax High Flow Turbo Pedestal Kit (WCF100185)

A cast 316 stainless turbo pedestal for the 2017-2023 L5P Duramax and 2019-2023 L5D medium-duty trucks. The factory pedestal has thin walls that crack, warp and in bad cases melt, especially behind an upgraded turbo with tuning. This one is thicker everywhere it matters, port matched, and flows 12.7% more than stock.

Designed, cast and machined in the USA. The up pipe flange faces are thickened to stop the warping that lets OEM pedestals leak, and the openings at the up pipes and turbo inlet are enlarged and matched to the gaskets. Four ARP turbo-to-pedestal bolts are included.
