I believe you can get thicker ring gears now and elminate the spacers...

I found that Mr Gasket indeeds offers such a spacer. They come in several thicknesses. Now I am on the hunt for how you determine what thickness to go with. They Start at 0.200 and go up. Anyone ever been down this road before???

Jonesy...I'm telling ya, skip the spacer idea, you'd be better served trying to piss up a rope. Richmond offers a thicker ring gear set to go with a 4 series gear in a 3 or 2 series carrier...look on the Jegs website, they're there. Or, call up Randy's Ring & Pinion, they'll get you fixed up...

Thanks, I'll go that route first. I am going to do this myself and also install the master rebuild kit at the same time. I have read all I can on doing the tear down and install. Kind of fuzzy on some of the inspect stuff prior to re-assembly but I think it will make more sense once I tear the rearend down. Jonesy

I am pretty sure that 2-series carriers are confined to use 2-series gears. You can buy thicker gears to run 4.10+ ratios on a 3-series carrier, but there was nothing available to run a 3.07+ ratio on a 2-series carrier when I checked a couple of years ago. Coincidentally, I am looking for a 2-series posi carrier if you end up selling it. Good luck, Tony
