41201-80183 is the part number for just the gear set but unlike the 4.3 and 4.55, if you want to run the 4.875 or 5.125 you need to use a different pinion flange as well as a ring gear spacer for the differential. There are some lsd's like ats or cusco rs that are made specifically for the 4.875 and 5.125 that dont require this spacer but if using the oem diff you will need one.
