WWJD (currie 9")?

[shmoken875]

Alright I'm looking at buying a Currie 9" housing, it has:
xj perches and high clearance shock mounts already welded on
limiting strap tabs welded on
v-cut housing welded to the tubes
rear truss
high clearance housing
31 spline big bearing currie chromo shafts

NO brakes included
NO center section "3rd member" included
Needs CS studs and possibly new shaft bearings

He wants $500 for it, my only dislike is the fact that the shafts are 5x4.5 (jeep) and in building my front 44, I converted to 5x5.5. I do have spidertrax adapters on my current rear that I guess I could use, but me thinks it would make the axle hella wide. Also I had planed to throw exploder disk brakes on and don't know how an adapter would change all that.

So gimme some advice people, what would you do?

Is it narrowed? If not you should probably just pull one from a junkyard for much less. Then just move the perches, shock mounts and you can even high clearance it really easy. You probably don't need chromo shafts

There is no way you need that much beef for your jeep. The 9" is a very stout axle.

[Arya Ebrahimi]

Seems like a lot of money, and only marginal improvements over the 8.25 with too many compromises.

I'd hold out for an axle closer to exactly what you want.

Edit: On the other hand, I just priced that housing on currie's website and it's $1300 for what you'd be getting. I wonder if you could get new shafts from currie that are 5x5.5 and sell the 5x4.5's for any kind of money. While you're at it you might think of stepping up to 35-spline shafts. Then you won't have anything to worry about

Also, don't forget that 9" thirds aren't cheap. If you bought a 3rd from currie it would be $12-1800 depending on the spool/locker choice(I assumed 4.86 gears but it doesn't make much of a difference). That's not to say you can't find a cheaper third, but I think $1000 is as low as I'd budget for a decent setup.

Just some things to think about

for all that coin, why not a doubler of sorts? is your 8.25 that inadequate? i figure if there is anything left on your jeep your right foot has yet to brake, then its prob not in need of replacement yet.

but my vote is to do nothing, and simply devote all your time and money into helping me work on my junk.....

I've been wanting a big bearing 9" for a while now, this is just one of those bang for the buck deals. See Ary's prices

A guy at work said he could get me one for next to nothing, and I'd gear it myself. The biggest price would be a locker depending on full case or not (I debated a spool, but I'm not ready to make that jump yet)

Dunno, just not sold on a doubler yet, auto seems to eat the difference just fine (till it craps out lol) And although the 8.25 has held up for me I can't bring myself to put all my faith in it, just trying to be pro-active. No worries man you know I'm game to work on that thing.

Thats pretty much what I needed fellas, had the shafts been 5x5.5 it would have been a done deal, even used that set-up shpuld go for near a grand or better. I'll just wait for a deal on another 9.

cody you going home soon?

Have you looked around the local junkyards? You should be able to get a 31sp 9" from a late 70's-80's F-150 for under $300 all day long. '78 and earlier used a 1310 differential yoke, '79 and later used a 1330 yoke. Just be sure to pull a shaft and make sure its 31sp, some people will try to sell you a 28sp.

As for strength, I highly doubt you would ever break anything in a stock 31sp 9" under your rig, no need for all that high zoot currie stuff. I haven't had a bit of trouble out of mine and I really abuse it.

I didn't say you wouldn't need/want a 9". I said you don't need currie. I just sold a 31 spline big bearing complete axle for $150. If you get one (even stock) make sure you get a nodular third. It has a big N cast into the case. The stock (non nodular) thirds have a weak pinion support that is prone to catastrophic failure. You can get a nodular case from certain cars with high HP or from after market manufacturers. Pirate has plenty of info on them. You should be able to build an entire axle for just over $500 that will be more than you'll ever need. (plus you'll already have 5 on 5.5)

thanks for the advice, yea I had read about the nodular center sections while researching, although I was not aware of oem hp thirds. I though I read somewhere that after market hp thirds use 8.8 gears, can you confirm or deny this?

[Arya Ebrahimi]

high HP = high horsepower, not high pinion

[shmoken875]

high HP = high horsepower, not high pinion

guess i still have more research to do lol I didn't even see the word "high"

Currie's high pinion uses 8.8 gears but True hi9 uses 9" gears

FWIW D&M has some thirds on a shelf by the door.

[tsmall07]

Here are the prices I just sold all my 9" stuff for.

Full detroit run briefly: $350
nodular third with new pinion bearing: $300
Complete housing freshly cut from under the truck axle: $150

I can't remember what I sold the 5.13s for

You won't need to pay more than that (or even that much) to have a setup that is more than strong enough for you.
