Is this a V-6 or a V-8? I assume it is also a automatic? There
is not much of a change from 3.55 to 3.92, is it really that
important? I would suggest driving a identical truck to yours, with
the 3.92's to see if it would be worth the trouble.
I have the 3.92/five speed and I'll admit, it will smoke the
tires without even trying.

It is very expensive. Most of the cost is due to setting up
the new gear sets. (Read Labor)

That's kinda high, but it will cost you more than a few
hundred. The gear sets alone will run a few hundred.
I might also suggest if you do decide to do it, now would be
the time to add traction control devices in the axles. I have the
Trak-Loc in the rear, and I love it. I would like to add a limited
slip in the front, but the front axle is a new aluminum casing and I
haven't heard of anything for it yet. I was apprehensive about the new
aluminum axle, but now seeing that it is a non-load bearing design, it
is no biggie.
