TJ rubicon Dana 44 gear sets are all thick but they have slightly larger ring bolts than the older Dana 44 carrier had. So you could buy a TJ rubicon Dana 44 gear set and just drill out the holes a little on a series 3 standard Dana 44 carrier to be able to fit them on it. I see TJ rubicon D44 4.10 gears go on ebay for $10. The 4.10 was standard from the factory in the TJ rubicon Dana 44 rear axles. Note that a JK rubicon Dana 44 axle is a different animal and parts for that are not compatible with all the older Dana 44 axles.
I was going to put a TruTrac in it so the carrier will be replaced. I think it has 3.54 gears in it now. I was going to leave the stock axles in it since I am only running 33s and the biggest engine I plan to put in is a 4.0L HO. Those should hold up okay under that load right?
