Carl, the Super30 kit has hardened/chromoly, 30 spline axles with
larger u-joints. Given these specs, do you think I'll still be pushing
my luck with 35's? Maybe I should limit tire size to 33's? I will be
using 4.10's both front and rear. Anything lower will result in to
high an rpm at 60+ mph with my existing 32's -- which still have 75 +/-
pct tread left. Right now gearing is 3.55 with the 32's. 4.0 with
130K miles and auto seems to pull ok -- so, I'm thinking that 33's with
the 4.10's should probably be ok. If you feel that the Super30 might
still be a little week with 35's, do you think it will hold up with
33's? What do you/others think? Thanks for your thoughts/input.

Bill, I know you love D35's. I'll give you a killer deal on mine when
it's swapped out for the D44. Interested??!

I wouldn't wish a Dana 35 on my worst enemy.
Braking is a lot more fun with 35"s, too.

The D30 with the upgrade kit should be ok if you take it easy.

I really think you would be happier with the 4.88's over the 4.10's. I had
4.10's on my 89 4cyl YJ with 33's and it was OK, but I wouldn't have tried
to turn 35's with them. 4.56 is the reccomended gear for 33's.

I would rather buy a new set of tires too early and have the better gear
choice than a bad gear choice to save some money on tires. You can likely
sell your old 32's on craigslist to help finance your 35's.

Something else to think about is bigger tires break more parts.

The main idea is to avoid 'incrementalism', that is, upgrading the same part
twice. IE, getting 4.10's from your 3.55's, then getting 4.88's when you
upgrade again. My theory is build the Jeep around the tire size. Pick your
tires and decide what it's going to take to turn them, and keep turning
them.

So, my final reccomendation? Install 4.88's, and the 35's early. Sell your
32's. Take it easy on your D30, but after you break it a few times, replace
it with a D44. Carry spare U-joints for both drivelines and your front
axles.
