I was wrong too dana 300 were only used 3 years, from 80-83. I saw one in clist for $200, so they are out there.

Wonder how much the adapters are to mate with the aw4 $200 isn't bad

Here is more info, if u got a 90 up xj u have a 23 spline tranny, shouldnt need the splibe adapter. All u need is a clocking ring and 7/8 thick adapter, to bolt right up. Or u can just bolt it in, but what has been said is the tcase hanges too low, have to shave from belly pan or something. I also think that its flipped, but idk.

Or you could spend a fraction of the money, keep your 231 and buy a SYE.

ctjkelley

I like this idea. I like the 300 but to many mods for what my plans are. Which brand of SYE is good? And are you bout done with that bumper? Lol

231 are good tcases and are wheeled alot!!! But if u are thinkin of regearin, with a dana 300 u gain 1.32 gear ratio. So in 4 lo if u have say 3.55 gears with yer tcase u have now u are runnin 2.67:1. When u go to 4:1 its like yer runnin 4.88 gears. Another benefit is 3.55 gears unless they are luggin alot gets good mpg especially compared to 4.88 gears. So u keep yer mpg gears in yer diff, but gain the super low in 4lo. Also u get an unbreakable tcase, tjat can handle chevy big block power. But yet a hack n tap is 99 bucks and either way u gotta buy a dshaft. But u see no benefit in 2 or 4 hi because its a 1:1 ratio like the np 231, so regearing is the only way u get power back on road.

I have 4.10 gears a 8.8 in the back a d30 up front. My drive shaft is like 29 1/2" compared to my stock which is around 32" if I'm not mistaken

Spideracdc

Dang right!! I think how u do end ratios is, times the tranny gear u are in, more than likely first, which for an aw4 is pretty low like 3.2:1 or so maybe lower, times that by your tcase ratio in 4lo which is 2.67:1, then times by yer gears 4.10:1. Makin yer overall ratio. Now take all that and pit in 4 instead of 2.67. When u double a tcase u times say 2.67 np231 by dana 300 4:1, makes yer tcase ratio, 10.5:1 which then would be yer tcase 4 lo ratio. Ridiculous crawlin then, saw a guy with one in a yoda at the rubicon, goin up straight up rocks, got outta the yoda in first and it crawled itself, he just steered and it was a 5 speed.

There.

My old toyota had a final crawl ratio of 216:1

ctjkelley

Wow that's impressive. I may try and find one to just keep around

Spideracdc

Yip that man knows best ^^^^^^ Mr. Marlin Crawler Himself right there. Too bad he disnt sell it to me and now Im stuck with a 2.02:1 ratio tcase but gear driven, not chain, or even worse a combo of chain and clutch driven like the 242.

Xj88

Watch it! lol.
I rock a 242 now

Spideracdc

There not that bad, well in 4 lo u have a stronger tcase than 231, which is a plus, and the full time 4wd, tho, idc about it, is a plus too, i just dont like a clutch bein in a tcase, but the aw4 wrks great with all its internal clutches. But u know y i dont like em.
