This TCI TH400 heavy-duty forward drum assembly is built with a larger diameter billet input shaft made from Vaccu-Melt 300 steel for very high tensile strength. The design increases lubrication flow and strength with a resized shaft diameter that spreads stress along the length of the shaft, from the high gear splines to the oil ring.
