You can't use the pinion from a set of 3:54 with a 4:10 ring gear, if that is what you mean.
That is WHY they are sold in sets with the pinion and ring.

I ask this in all sincerity because the thought just came to me. I just went from 2.72s (2.73s?) to 4.10s so this is just for my personal knowledge. And this place is where I get to pick the best info.
Yes, they are a matched set from the factory. They actually lap them together like you do valves to valve seats for better wear and less noise. There is more to it than that, but that is the Cliff's Notes version...

I like that Power-loc system, makes sense. I want to know about the Hydro-Loc system like was used in the front of some of the Grand Cherokees. They were open until one wheel spun about 5 times compared to the other wheel, and a hydraulic pump would compress clutch disks and limit wheel spin. I think they'd be the best bet, but I cannot remember what is under the Grands.

Thanks Lumpy/327. You answered more than I thought of. But as Cutlass said that like dizzy&cam....they "wear" or are made to fit together in a particular manner. Measured square area w/machinists' dye I guess?
So a ring gear should be changed along w/the pinion...or have them lapped to fit together in a certain manner.i
And Lumpy it never occurred to me to create a "custom" gear set. BTW Lump, your gearset SEEMS to work out to a 3.82 . But I'm assuming the different tooth count (and tooth angle?) would only make it out of the garage before Grenading
The only "FINISHED CJ" is the stripped one in a junkyard w/a bent frame.
