Torsen carrier compatibility

[PetroleumJunkie412]

Saw the FX4L2 diff was on crazy sale on torsen's website:

Torsen® Traction

torsen.com

So... I have the weirdo 8.8 in my 2011, and if memory serves, it is the big tube with the 28 spline axle shafts.

What would it take to make this fit, or am I better off just "buying up" to the correct one to fit 28 spline axle shafts?

Is it as simple as finding L2 axle shafts and swapping them into my diff?

Nvm, read @pjtoledo s write up in the tech section... did t remember that one being there.

Either way, looks like I'm stuck with 28 spline shafts unless I get fancy with machining

Update 2: called torsen, spoke with Tim.

Theyre checking if there's a way to convert the FX4 carrier to 28 spline. Small chance there is. Since it's the gears themselves that hold the axle shafts, there is a chance they can just be swapped.

I'll update if/when I hear back.

maybe you can shorten Explorer shafts. not sure what to do about the ABS gears though.
there might be enough extra spline that cutting off a half inch won't matter.

don't forget the pin is only 3/4"

crazy thought, if the bearing surface is wide enough on Explorer shafts maybe put them in as-is and spacer the brakes out.

need any pics or dimensions?

Maybe on the pics... I'm hoping torsen comes back with an easier answer though. If it's as simple as a gear swap on the fx4 diff, then I'm golden.

If so, I'll let the rest of you know if it's possible after I've ordered mine

for your viewing pleasure, Torsen teardown.
there are 2 different Torsen designs, this is the simple one. and they don't work the same if you lift a wheel.

Simpler than I thought...

Since this is for a pavement and gravel road build, I'm not too worried about lifting a tire, just want more bite than a clutch pack offers.
