Coyote_94YJ A Dana 44 from a Rubicon has the same width and bolt pattern as your Dana 30.

cowboy724 Thanks for the info. I've thought about upgrading the transmission to an NV4500, but it's kind of bulky looking. Didn't know if I'd have any issues getting it to fit in. I plan to go SOA with a 1" body lift. So maybe there will be enough room. As I said before, I want to retain a 5 speed transmission.

Also was hoping to upgrade the front axle as well, but not sure what to go with. Are there any front axles out there with the same width and bolt pattern as the Ford 8.8's out of the explorers? Bolt pattern being the same isn't so much a necessity, but convenient when rotating tires.

I disagree. The AX15 should stand up the the demands of a 350, but that's just my opinion. But he does make a good point. The AX15 is a medium duty transmission. If you're going to go for a 350, why not go all out and find a GM transmission? In my opinion, you'll have more luck with the longevity of a GM transmission. The AX 15, is one of the better transmissions found in Wranglers but still....GM transmissions can take an x-large can of whoop ass that the 350 will put out.

Have you started considering the rest of your drive train? The transmission isn't the only thing you're going to have to replace..

schnutzy if your going to grab that AX15, make sure you grab the T case as well. the output shaft on the AX15 will not match up to the Tcase behind your AX5

Chevy 350 vs. AX15

I'm looking for parts to upgrade my 2.5L 95 YJ. Found a TJ in a junk yard with a good AX15. Will the AX15 hold up to some rough trail riding behind a 350? If I go with a built 350 that has a little more horspower than a stock 350, will it still hold up? I'm going with a Ford 8.8 rear and think the AX15 might be the weakest link here. I want to retain a manual transmission.
