Posi-Trac??????????

[SuperDuty1]

I would like to upgrade my differential to a limit-slip. I have read thru some of the different ones. I don't want an Air locker or E-locker. I want somthing that will work on its own. I was curious about the Power Traxx. The differential will have to have good road manners, I don't want it trying to bind up when making sharp turns. Does anyone have any suggestion?

IMO the Detroit Tru-Trac is the best limited slip on the market. Most LS use clutches to enage the axles, the tru trac uses gears. I know of nobone who has broken one.

Does anyone else have any experience with the detroit tru locker or any other brand?

my buddy put one in his work truck when the stock carrier broke. He does basment work. They haul around a lot of stuff in the bed of the truck and pull heavy trailer.(bob cat,mini-X's and such) He loved the tru-trac in the rear axle. He said you could not tell it was there untill you got on the gas hard and it would light up both of tires everytime.

I had one in the front of my off-road jeep that I got used and I use it for about 3 year. The case broke b/c it was ment for a C-clip axle and did not have as many gears in it as it would for something that is not a C-clip alxe(like the 10 bolt I am runing) I know if I was to buy something for my truck I would buy a tru-trac. Also you do not need any spec. stuff to put in for clutches since there are none.

I appreciate your info. I did some research on the tru trac. It might just be me, but I really don't see this design working very well for constant daily on & offroad.

As opposed to a unit that runs on clutches?. Concider that an automatic transmission runs on clutches, a standard does not. A standard uses a clutch to engage, and what part do you replace most on a standard trans.... Its the same theory. The clutches used in virtually every other limited slip differerential wear out. Plus most require a friction modifier to work properly. The Tru-Trac does not.

Where is a good place to purchase one and do they make one for the front diff.

Are you doing the install yourself? If so I'd go to www.fourwheelparts.com. If you are having the work done for you, hit a local 4x4 shop with a good rep.

Other places to check:
