I put a Peloquin in the tranny of my Syncro, which
does not have a locking diff.  I can certainly tell
the improvement of traction in snow or sand.  I'd
love to have one in the tranny of my '81 air-cooled.
That plus Hakkas would be a huge improvement over
the open diff and all-weather tires.

My '01 Jeep Cherokee has a limited slip diff and
I am amazed at how it performs in 2wd, even with
almost no weight in the back end.  Again with tires
with a good tread for snow.
