8” IFS Clamshell w/FRS Torsen

Diffs are on their way to be rebuilt, hopefully know all the truths here soon.

 

Subbed because awesome.

 

They were delivered today, believe me I’m eager and trying not to bug him too much.

 

Did some more reading: land cruiser gear won't work because it's high pinion, the clamshell is mid pinion. Looks like drilling out the holes another 1mm is solution.

 

This is definitely the concern with the LC 4.10 gears, but ZUK has a set and is going to try them. If you look at the diff from an LC, it definitely looks more mid-pinion than previous models that were clearly high-pinion. Won't know for sure until he does. I'm still hopeful for a drop-in solution w/o drilling, for everyone's sake

 

And when I say it looks mid-pinion, I'm referring to the picture below, from this build.

However, this image is not so mid-pinion :

 

We’ll know soon! Ken just sent me this pic of the diffs I sent him laid out on the bench!

 

I’m definitely interested in the outcome. My other Toyota trucks I’ve run front and rear truetracs, makes the truck a traction finding beast. I was very disappointed with the lack of such option on the 2nd gen.

 

Interested in how this will turn out. I have a awd v8 4runner and been looking at some options also

 

What I wouldn't give for a V8 AWD taco, but I don't really want (or have the means: time, garage) to do a big swap like that... so I'll piecemeal a V6 version together instead

 

It's a no-go on the TLC 4.10 gears.

 

Subd.. been wanting to convert my taco to awd.. hopefully theres a way

 

Swap the manual transfecase from the 6spd fj and run the fj front diff setup that deletes the add

 

Any idea if ill need the fjc ecu and any wiring as well?

 

There’s no wiring

 

How do you plan on going about testing if it works once installed?

 

I mean, once installed in your truck

 

Well, torsen differentials are mechanical in nature... there isn’t really anything to test. Once Ken tells me he was able to get a good alignment with the FJC 3.91 gears on the FRS carrier it’s pretty straight forward.

My plan is to regear the rear to 3.91 with a TrueTrac and then swap both diffs into my truck. As soon as I can after that, I will get the AWD transfer case and necessary bits ordered to complete the drivetrain.

 

Maybe I’m not entirely following what you’re saying here. I think the only piece left, assuming Ken gets the 3.91 gears I sent him to align well (after drilling out the FRS carrier) is to get the non-ADD diff tube back onto the diff and shove the driver side CV axle into the front diff.

Might be silly of me, but I’m not concerned about this piece. I’m 99.9% sure all of that will fit without issue.
