I have a 96 xj. I think I have an 8.25 rear end. I tried to find some pictures on the internet of the two possible rear ends and I think mine is an 8.25. Is there a sure way of telling? Vin codes? If I have the 8.25 how do I tell if I have a trac lock factory limited slip? Would having one affect being able to install a lock right in the rear end. Thanks for any information anyone can provide. I am ready to order a lock right but I want to get the correct one. Thanks again.

not sure about lockers, but on your Diff cover there should be a small metal tag under one of the bolts that hold the diff cover on, on there will have the info about the diff and gear ratios, limited slip ect...

i'll try to find a good page on checking for lsd i believe that you can check by getting one wheel off the ground, but it should be done carefully. I'll try to find a link on that one.

If you have an 8.25 the Chrysler star symbol is cast into the bottom of the center section. If you do not have the tag under the cover bolts you can take your VIN # to the dealership and they should be able to run it through their computer and tell you if there's one in there.

I would like to thank everyone for the help. I have looked at the pages with pictures and I have come to the conclusion I have the 8.25. Now all I need to figure out is which locker or posi to get. Thanks again.

There is really only one out there for the 8.25. That is the "powertrax no-slip traction system". It is an auto locker that functions as a limited slip initially but goes to full lock when there is a predetermined difference between the rear wheel speeds. I have made alot of inquiries of shop owners who install and wheel the powertrax as well as individual xj owners. I have heard of two failures and the folks have said that powertrax sent them a new unit with no questions asked. Of the others out there runnin the unit, all have nothing but good things to say about it. I am ordering one for my '98 xj and will have it and new gears installed sometime in February of this coming year. If you haven't gotten one by then I will let you know what I think about it shortly thereafter.
Detroit is supposed to be offering sometime later next year their ELECTRAC on demand locker for the 8.25 but they have not said specifically when.
