I have been looking to make my 2wd cherokee posi (limited slip) whatever how many spline does my rear have? I was told it's a 8.25 which I thought only came in 4x4's but not sure. It's a 1993 model and wonder where I could buy this unit. Thanks

The specs for the 91-96 8.25 axle are: 27 spline, 1.17" diameter shafts, 8.25" ring gear, 3" axle tube

The specs for the 90-01 D35 axle are: 27 spline, 1.18" diameter shafts, 7.58" ring gear, 2.62" axle tube

Now, There might be a tag on the diff cover to help you identify it, but not always. The easiest way to tell is to look at the bottom of the axle housing. Here's pic. The 8.25 is on the left, D35 is on the right. The key giveaway is the square lip on the bottom of the 8.25 axle housing. You can tell the difference at a glance.


As far as where to get an LSD for an 8.25, I've never looked into buying one, so I have no idea. You could try some of the online vendors that sell lockers...I would first try doing a google search on it though.

Check out 4Wheel Parts Warehouse. They have several options of lockers and such for the 8.25".

Another thing I was wondering is if I decide to add a three inch lift, will the posi help it keep good exceleration or should I not worry about it. I hear alot of things about losing power when lifting but I just want it for looks and want to keep my 4.0 power....thanks

no offense, but i think you need to go to google and do some searching on "limited slip", "posi", "spool", "locker", "traction devices" and other words you may have heard. and read as much on 4x4 forums as you can. it sounds like you've heard to many gearheads talking about stuff they have in their vehicles, but you don't know what they do.

now i'm not trying to insult you, but it sounds like you need to learn the basics before thinking about changing things on your jeep.


now about this part:

"posi" is sort of a improper used slang term for chevy limited slip. but regardless, it still is a "traction device". and that's exactly what it does. it handles "traction". that's why you have to do some research and learn some basics on what traction devices do. there are lots of different types out there, and they all do something slightly different and all have their pros and cons for different situations.

traction devices will not affect your acceleration on the street. that has to do with gearing. it's not the lift that hurts your acceleration, it's the bigger tires that people put on once they get a lift. to turn the bigger tires, you have to re-gear your differentials. so go and do some searing on "axle regearing".

My jeep is a daily driver not a 4x4 wheeler. I just like the lifted look and don't want to sacrafice the acceleration or pick up what ever you want to call it. My friend lifted his wrangler and he said somthing about regearing. I know the tires size effects the ride which I failed to mention I wanted a 3'' lift with 32'' tires, no flares....strickly 4 looks. How should I approach the equation if needed to maintain good performance?????????
