hi guys I have wrangler X with 3.21 gears and now i want to put 4.88 gears and a detroit locker in rear (dana 44) and a E-locker in front (dana 30).

my question is for the rear o i need a 3.73 and lowers or 3.92 and up
and the same question for the front : 3.54 and lower or 3.73 and up


thank

 

I've been looking for lockers myself. I have a Sahara. D30 in front & D44 in rear. The only lockers that I saw that would work were the Aussie for the D30 or the ARB air lockers. I was looking for the detroit, but they don't make them for the JKs' yet. All I was looking for was an Automatic/Limited slip locker. If you find anything let me know. Also you would be looking for the gear ratio that you are putting in, not what you had in. So you would be looking for 3.92 & up for the rear and 3.73 & up for the front.

if you look at this site you can see that they have use a 3.73 and down auburn in the rear because the jeep jk use thick gears and they says that we can use any locker

so i just want to be sure of this before older my stock

 

The Detroit should work with both axles. As shown 3.73 and down for the 44 and 3.73 and up for the 30. The 30 carrier is the same as othe 30 carriers.
