Since I am getting my rearend rebuilt, I've decided that upgrading is a must. Do you guys think I should just put a better type of limited slip into my Bronco (such as a Detroit TrueTrac), or should I go with a full locker?

What are the benefits/disadvantages? I do most of my driving on the street, but I like to know that I have some serious off road power when I decide to take it into the dirt and mud!

BTW, the ARB AirLocker system is out of my price range!

 

As far as limited slips go the true trac works very well. My friend just put one in his jeep and he has been very happy with how it performs. And since you do most of your driving on the street I wouldn't recommend a full time locker like the detroit so that basically just leaves some type of automatic locker like an EZ locker or lockright, but then you have to put up with the popping sound it makes when it engages and disengages.

Now IMO I think a locker in the front works better than one in the back because if I can get my front tires past an obstacle my back tires have no problem following (it might be different for mud and dirt though) and if you have manual hubs you don't have to worry about added stress when driving on the street. Thats why I put the lockright in the front and left my rear open until I can afford a selectable locker like the ARB.
just my 2 cents

 

We just put a used detroit locker in my boy's bronco. I put it in a class 8 offroad pre runner for a pre run of an old Mint 400. The work great but produce weird handling when the lock/unlock under high speed desert running. The back end likes to come around. So I put a spool in and the locker sat for 15 years and now it works great for my boy's offroading. That says a lot for the quality as it still works great and survived a pre run under some old class 8 horse power. Does make noise when working but no clutches to wear and you get both wheels when you need them.

 

I like the Eaton posi. It performs very similar to a locker but is very streetable. I have had the factory bronco posi then a Auburn and I liked the Eaton the best.

 

I talked to my rear-end guy, and we decided to put in the Eaton Posi-Traction unit, since I do drive quite a bit on the road. From what he says, the Trac-Loc is a lot weaker, do to the fact that it uses clutches instead of gears. Anyway, I will post when all the work is done, and let you know how I like the Eaton (and my new 4.11 gears)!
