Genuine Holset, 60mm inducer, Upgrade Compressor Housing & Wheel combo for 1991.5-1994 Dodge / Cummins 5.9L diesel Turbochargers.
This Housing & Wheel combo is the largest available, genuine Holset housing & wheel set to fit the stock turbo! It gives a massive increase to the compressor flow capacity and adds a map width enhancement slot to reduce compressor surge on 91.5-1994 air-to-air intercooled trucks. It increases the compressor wheel inducer size from 54mm on 1991.5-1993 1st gen. trucks, and 56mm on 1994, 2nd gen. trucks to a 60mm inducer.
This housing & wheel combo is a direct fit on these year trucks, if they have the O.E. part number turbocharger. (attaches to the center housing with a v-band, not snap ring connection)
