The LSD mod I came up with was to remove the pre load springs and add extra clutch plates.

Loose when your off the throttle and quick to lock when you load it up.

I have a Torsen in the back. Basicly, when I need to go I just pre load the brakes a little and the internal friction of both diffs goes up very quickly.

In the snow, it does drive a little different. In 4WD on snowy roads it feels a little squirrely above 45 mph. Then again its a SWB on tall tires in the snow!!!

In the deep stuff if you want to go around a corner you need to use the throttle. Drive it easy and it just pushes the front end.

Goose the throttle cut the wheel and you're good.

It works for me.... I dont know if anyone else tried the no preload extra clutch front diff or not. That was my answer to the LSD units being tougher in the snow. Way better than open.... Off road, pre-load is a better call. Most times I'm on the road so thats what I went for. Regardless, its still better than open and very fun to drive in the snow.
