GM IFS & Dodge (AAM) 9.25" Reverse High Pinion 5.13 Nitro Ring & Pinion

Tech Note:

Direct fit for 2007 & Newer Dodge 2500 & 3500 with OEM carrier ONLY.

2003-2006 Dodge vehicles using this ring & pinion on an OEM carrier require MRG925A ring gear spacer or the 07 & newer type carrier NC-AAM9.25-COM.

2007 & newer Dodge 2500 & 3500 will still require MRG925A ring gear spacer with aftermarket air locker such as ARBRD197.

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.
