What diff to get for f series diff?

[Mirko]

Have manage to get my hands on a F series housing and gonna build it for my AE86. Was thinking of getting a Eaton Detroit Truetrac Diff for it. Its going to be driven on the street and circuit racing NOT Drift.

Wanted to get peoples thoughts and any experiences with them or any other good diff's for them?

[LittleRedSpirit]

never used one and I think most people havent on here.

[Mirko]

Yeah haven't either but hear good things

[drift kid]

F series is hilux diff right? I'm looking at these options too for my hilux daily but I don't want the harshness of a tru trac, I am going to look into a clutch type LSD like a kaaz or a trd style

[Mirko]

No g is hilux there are 2 f series diffs. One from a targo that u have to cut down and the holy grail out of a Cressida where all you have to do is change mounts that's the one I have

[Mirko]

Also true trac are not harsh at all from what I read. The Kaza 1.5way in my s14 is harsh

[drift kid]

I have been told that the tru trac is harsh in that it is either locked or not, there is no inbetween smoothness as it is a gear type lsd not a gradual slipping of a clutch disc if you know what I mean, and kaaz probably aren't the best to reference off of, they are kinda noisy and rough but my trd lsd in my 86 is insanely smooth and I would love to get something similar to this for my ute

A mate of mine has one in a xy and he loves it. Its very progressive on engagement/disengagement.

i cant comment on the noise of it tho, 406ci stroker makes the diff hard to hear.....

A Truetrac as in a Torsen?

[Big T]

This is totally wrong. The notion of "locking" a torsen is not how it functions. It transfers torque to the wheel with the most grip and hence is working nearly all the time. This means it is smooth in transition.
