I'm rebuilding my chry 8.25 id like to go with a detroit rear but idk if that's the thing I should run. I'm into just all around wheeling environment anything I put in front of my jeep. And I'm going to be running 33's should I go with a 4.10 or a 4.56? It will more than likely be driven to the trail also. Just would like other peoples perspective

 

Your 1991 Chrysler 8.25 has 27 spline axles. If I were you I would go to Randy's ring and pinion and get 29 spline shafts and 4.10 gears. For a locker I would go with a Power Trax No-Slip. That would give you a rear axle that would hold up to anything you will likely do with a Cherokee. Just my .02

 

I should have been a little more detailed I bought the rearend from a guy he said it was out of a 95 and has the 29 spline shafts.

 

Yea I've looked into the powertrax just not enough. Ill probably run 4.10 but a lot of people say to go with a 4.56 and I kinda think that's a tad much for 33

 

late year 96 and up are 29 spline. Everything before then is 27 spline.

 

If it is a 95 and has 29 spline they have been replaced, because like Frankz states the stock spline count for a 95 is 27.

 

I'm hopin it is if not I'm not worried my intentions were just getting the housing to get it built. I have a d35 and I know that pos ain't worth a dime. But I will look at the powertrax thanks for the info

 

Randy's has 29 spline 1541H axles for $70.62 for the 8.25, or JY the stock 29s, they will make the 8.25 strong enough to handle your 35s. ( sorry I guess it is for 33s )

 

for 33s just get 4.88s. you'll love the extra power you'll have left over with the lower gearing, and you'll be all ready to go 35s when the time comes.

 

I've thought about the gearing aspect but I'm doing some minor to medium engine mods so I should have enough power to run through what I do. And 33s are probably the highest id go on a xj.

 

thats what everyone says

 

Hahaha yea I know ill probably go higher at some point but that's my plan for the moment

 

just do it right the first time and throw them 4.88s in there! yes you'll lose a little bit of highway mileage but you didnt buy an XJ to get decent mileage now did you?

 

That is a point. Id like to get better than my truck city is 10 its so crappy lol...but no I'm makin it to roll it to roll it back over and keep rolling

 

As far as I can tell my 8.25 has the stock gears(what ever they may be, I have no idea how to check). My jeep is a DD and I'd like to keep my MPG decent (for a cherokee). I have 32" tires and would like a little more power for mud, any suggestions?
