RCV shafts and other upgrades (44)

[90xj_zach]

I'm running a 77 HP 44 out of a 77 F150. I am about to purchase after market shafts as spares (which will obviously be my full time shafts soon enough).

I have no problem spending the money on RCV shafts, but do they offer the 19 spline stub shaft option? I have brand new Warn premiums that will obviously not work with the 30 spline stub shaft I have seen them offer.

Anyway, any other shafts people have luck with? I have a buddy that wheels the crap out of his set up with Yukon super joints and never broke one yet, those are pricey too.

Thanks fellas.

I'm pretty sure RCV can custom make anything you want. Just ask how much extra it'd be to get the 44 shafts in 19 spline. Then see if its worth it staying with your current hubs or getting ones for the 30 spline.

or Standard config shafts (U-joint):

Why would you want to do that? I mean your all ready spending 1400$, why not just get a 200$ set of 30 spline hubs and sell the 19s.

Regarding the RCVs, I could be wrong but I don't see where it states that it has the 19 spline stub shaft, and the picture seems to show a 30 spline one (although that doesn't mean much).

I have never seen anyone breaking the stub shaft, if it fails somewhere, it is at the ears because a u joint went, not the splines.

a buddy has been through a number of 19 spline hubs, with chromos. hes now running RCVs in his D44.

the gain isnt (solely) in the strength of the stub. its more of an upgrade to the hub to match the strength of the RCV.

They are 30 spline inner and outer.

You want the locking hub upgrade.

Nope, this is the one he wants.

LOL. I just saw a 30 spline stub shaft break this weekend. It was the old warn hub conversion shaft for a dana 30. This was on the 4643 ultra4 car. Apparently it was a 12 years old shaft.

I've also heard of RCV's failing on JK 44's. This is probably due to the weight of the JK, but under the right circumstances anything can break.

What am I missing here? What exactly is that? Is that to convert my 19 spline lock outs to 30 spline, or is that something you guys are recommending I do after purchasing warn 30 spline lock outs?

 

[Serious Offroad]

You need it to replace the 19 spline in your existing hub.

 

[90xj_zach]

Thanks for the reply! So basically instead of buying the new hubs for about $200, I simply buy those for my existing Warn premiums. Sounds great. I assume it isn't terrible to install those? I'm mechanically inclined, but have obviously not done this job yet. When I put in the lock outs, they come intact already.

 

[Serious Offroad]

Very easy.

If you're going to run an axle with manual hubs you should learn how to tear the hubs down and rebuild 'em.

I've broken more 19 spline stubs inside the spindle or at the splines than at the u joint for what its worth. A couple stockers and a few alloys.

Yea, I think I've decided to go 30 spline. What did you end up doing after breaking multiple short shafts?

kept throwing more shafts in it.

Last set I had in there were nitro's they lasted almost 3 years then I sold them. Mosers, stock, and yukons all broke on me within the first wheeling run, or after several months.

 

[90xj_zach]

I see. What luck did you have with U joints over the years? That initially was my biggest concern with the dana 44.

With CTM's you rarely to never break a u-joint, typically break the shaft at the ears or in the spindle.
