d30 4.10 with 33s and other upgrades to lift an mj?

[GirsMJ86]

ok I'm lookin into gettin new axles for my 86. and i was wondering if i need to get a better axle then the 30. and just needed to know if the 30 with 4.10 will work with 33s.

At the very least, upgrade your axleshafts and front driveshaft. The 3.4 might be a good match for 4.10s, but 4.56 or 4.88s would be better. It depends on your budget.

Jeep on!

If you have an auto 4.10's will due, but run an aux trans cooler. If you have a manula I stroblgy suggest 4.56's or the 4.88's.

well my mj is an auto just to throw that in there also.

and what about if i just threw on my 3" lift with 31s? would the set up i have work? or do i still need to upgrade ujoints, axleshafts, front driveshaft, and aux trans cooler, and go higher then 4.11s or not? also i will eventually goin to the bigger lift and tires and the 3.4 but those are not in my budget for right now. so what i need to know is where are some good sites to find everything listed above and also a new d44 carrier to fit the 4.11s and up. because i don't have the yards around me to find parts. also what would some good donor vehicles be for those parts?

What kind of driver are you? I ran 4.10’s with 35”-37” tires on a 30 your 7 years and only broke one shaft due to u-joint failure. That was with an AX-15 tranny. Now lock that same 30 and it won’t hold up long.
