2003-2006 Dodge vehicles using this ring & pinion on an OEM carrier require MRG925A ring gear spacer.
As an alternative you can purchase a 2007+ OEM carrier AAM9.25CAS-342 or aftermarket locker which do not need the ring gear spacer.
Nitro gears are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford & Toyota. They are precision machined using computer controlled processes, heat treated, CNC triple-lapped and Rockwell tested for hardness. These extra steps ensure excellent fitment, ideal contact pattern and smooth, quiet operation.
