I was saving up for JK axles...but this is much less expensive. Is it worth it to drop chromoly in a D30?

The 30 spline axles will also require you to get a 30 spline locker. That's great and everything -- and probably not a problem if you were looking into getting a locker anyways. But if a shaft does break (it still uses the 760x u-joints that aren't indestructible) you have nothing to replace it with (assuming you don't buy two sets) since the best warranty does nothing for you on the trail. At least if you stay with 27 spline, you can still slap in a stock shaft to get you home.

If you do manage to break a chromo shaft, it will likely be one or more of the ears due to u-joint failure. The next most likely (or perhaps the most likely) thing to break will be something internal (R&P, crosspin, and/or carrier).

The reason I mention this is that even if you do upgrade to the 30 spline, it's likely that additional strength won't really help you much because even 27 spline chromo shafts would be "stronger" than your u-joints and internals -- so those will probably give out before the shafts regardless of spline count.

Yes, it is worth it, IMO, to upgrade a D30 to chromos as opposed to going with a Dana 44, but it comes down to a matter of preference. If you break u-joints on a 30, you are going to break them on a 44. You can beat on a properly built D30 with chromos pretty hard (at least on the east coast) before anything gives out (I know from experience) -- but don't expect to wheel KOH-style with it. Yes, a 44 is stronger than a 30, but whether it's strong enough to justify swapping out a D30 depends on your situation and preference.

If these were for a ZJ, I'd suggest dropping the extra coin on the RCVs, but the non-standard width and need for tone rings probably puts custom WJ axles from RCV well above the cost of these shafts.

True. But those come with the Spicer ones. You are going to shell out good money for a set of aftermarket u-joints -- such as CTMs. The big issue though is that not all of the aftermarket u-joints are streetable without shelling out for lockout hubs. The CTMs use brass bushings instead of needle bearings which aren't very happy on the street with unit bearings. The Longfields might be streetable since they are supposedly a heat-treated, beefed up Spicer joint, but I don't know.

Just something to keep in mind.

EDIT: I hope you think I'm not deterring you from buying the WJ chromo axles. I'm sure they are as good as any u-jointed chromo axle. Of course, seeing as WJ 30 options are pretty limited when it comes to shafts, I'd be just as excited as you. Just trying to throw some ideas out there so that you don't buy something that leads you to spending even more money if you don't need to.

No No !! Not at all'' I'am very excited, and Thanks very much for your Imput'' your ideal about the 27 spline shafts , was very good, Good Ideal''' I do thank these shafts are a little spendy, and for the only Chromo shafts, on the market for the WJ D 30's, But I know some one that makes front drive shafts for everything'' {But the WJ,} So I thank he's going to be very interested in thses shafts, and maybe I can get the same for a little cheaper ? well ''we'll see'' and Thanks Sir Fuego''

I just got the Chromoly/U-joint shafts from IRO recently..I found out the shafts they use are infact d44 chromoly shafts. So whether you stay with 27 spline or go 30 spline, they will still be the same diameter of a d44 with the benefit of being chromoly and having U-joints.

There does not seem to be any warranty at all on the IRO shafts. About a year ago, I had an extended conversation on this with IRO and the manufacturer they use. If this is important to the purchase decision, ask a lot of questions.

The RCV shafts can be made for a WJ (I spoke with this manufacturer too) for $100 per shaft customization fee. That means about $1100 for a set.

All that said, I still may get the IRO shafts. I just wish they could get the volume up to where they could be sold for maybe $600 per set.

Is'nt the D44 front drive shafts for, lets say the TJ shorter, and the JKs D44's are longer ?? Then how are you going to get those shafts in a D30 for the WJ ?? did any one forget to mention, that no one has any spec's on the WJ D30 shafts, and the Dana Gods of D30s dont want any one,to have the spec's , so with that beening said, Dana has'nt released them, so why are these out there ?? and there sure that they will fit the D30s - How''''' I want to see some Pics !
