With a brand new 6" lift with new springs, shocks, everything, what is the MAXIMUM tire I can slap on it? Is 36's pushing it too hard with minor fender trimming?

Wow. That still goes down the road?
I've been twisting off 30 spline 4340 dana 44 shafts with 35's. I just had to upgrade to 35 spline shafts.

Mdub said:It runs real nice. Exactly the same as stock in fact (went from 3.07s to 4.10s and 27s to 36s - exact ratio). AX15 is much different than the AW4.
Running 36s with 4.10s on an AX15 is like
running 36s with 4.88s on an AW4. (Actually if you use the a calculator you will find it is more like 5.57 gears - but real world driving, it's more like 4.88s)
Check for yourself: http://www.grimmjeeper.com/gears.html
First gear in an AX-15 is 3.83, AW4 is 2.8. This comparison alone is kind of deceiving because the torque converter in an AW4 helps the AW4 a great deal.
Mdub said:Your point (as you know, cuz you made it) about the 27splines breaking with the 36s is EXTREMELY VALID. I've been fortunate to never break a shaft yet, but believe you me, I carry a spare. I run it pretty hard too, not EXTREME, but I finish all the trails I start and I start some pretty good ones. 8.25 is a nice little axle. But if you ask MattyJ, he's broke several, but you Cali dudes are Nuckin Futs! What is your locker in the rear? I run a no slip which is pretty forgiving. And now that we talked about it, I will surely break a shaft next time out.

cal said:That would be valid if you never left second or maybe third gear, but if you drive on the highway .. you're not leaving third gear.
Mdub said:Dude, 4.10s with 36s is EXACTLY the same as 3.07s with 27s (stock config). And as far as rocks go, I've done plenty of 'em. I've never needed more gears. Sometimes I'd like to have more but not at the expense of a top speed on road of 50mph.
