TCS Billet Output Shaft 4×4 47/48re

Standard sized 23 spline 4×4 47re and 48re billet output shaft produced by TCS from 9310V alloy. This fits 4×4 (Dodge Cummins Automatic 1996 thru 2007) and is a recommended upgrade for trucks exceeding 650 HP or regularly drag race, sled pull, compete in dyno competitions, burnouts, etc. For trucks exceeding 1000 HP, there is a fat 29 spline upgraded version that requires transfer case input shaft changes and modifications.
