Probably because it's (iirc) rated for 450 foot pounds torque when our engine only produces 235.
Nevermind, I was backwards haha.

I believe you have it backwards. You're talking horsepower. The 4.0 puts out about 235 horsepower, but only 190 pound feet of torque.
Unless you're running a stroker or something.
Beef up your brakes first, then beef up your 30 a little(put in fresh 760s and tack weld the caps or buy some chromos), diff cover, some bracing and trussing maybe, , then re gear, then sell 31s and buy 33s. Plan to regear as soon as you can afford gears...
I have the gears and for the 30 and 8.25. I'll find a new carrier. I found a good source for trusses. What do I need to do on the brakes? Just increase the size?
:dunce:

1. Black magic brakes(he uses centric premium rotors and pads
He owns his own formula and has custom pads made. They are hands down the best thing on the market, and its somewhat insulting to call them Centric.
His pads alone is the best upgrade you will put onto an XJ, except maybe for a stroker.
I am still recommending 33s and not 35s and carry spare front shafts . On 33s your brakes should be ok.
You have 3 options for the front brakes the way I see it if you feel you must got to 35s:
1. Wj swap - can range between 500-1000$ depending on how you source parts
1. Black magic brakes(he uses centric premium rotors and pads
2.go on rock auto and swap in centric premium calipers/rotors/pads
WJ is the best but the most expensive and time consuming. Black magic is a fantastic option too.
As for the rear, just make sure you have good shoes and the drums don't have any ridges, and make sure the wheel cylinders are in good working order.
If you don't already have a dual diaphragm booster and master setup, do that.I don't recall what year your rig is.
Any tire over 35" on a dana 30 and you will need many things and I would not do that unless you are ready for the WJ swap or you might hate your brakes.
What do you guys think about an axle sleeve for the Dana 30? I am looking at one at Iron Rock Off Road.

jeez i don't disagree, but do any of you guys have a 5sp? I don't use brakes that often.
im sure its in the thread somewhere to convert to rear discs......
