With the powertrax lockers, all that matters is what axle you have (you should have the chrysler 8.25 unless it's been changed) since all it replaces is the spider gears.

 

well.. another question, what is our rear ends Gear 8.25" , or what..

 

nvm, you may have just answered that.. lol, thats what i mean as in you guys reply fast

 

I feel stupid.. but what would be the spline needed?

 

Year does matter, 97+ are 29 spline, 96- are 27 spline.

 

ok thanks!, while your in here.. wondering about ur exahust, aero turbine, first off sounds unreall.. but can most parts stores get this?.. and are you runnin single, or dual? headers or not?

 

+1.

Here is a good site for rear axle info on the 8.25"

And here is several pages on all axles:

I'm running single 3" with a 3" cat, no headers yet but I did just get a pair from the junkyard. Some autoparts stores can get ATs but your best bet is online.

 

Oh yea! AND I LOVE IT!

 

I just got done putting and Eaton Detroit locker in my '93. It takes a little getting used to after a LSD, but overall really happy with the results. I would not do it myself again it took me a couple of hours getting the backlash right. Man its been almost a month since I have done it still running strong.
