As the title states. Anyone break one? I'm contemplating getting a set of cro-mo rears but I cant recall seeing/hearing about someone busting one. Lots of bends, but no brakes.

I was on the trails with Chris (FastTrack) and he snapped a rear shaft attempting a hill climb and twisted the other rear shaft as well.

Fairly common. I have seen it several times on the trail.

What sucks about the rear Rubi axle is that the shafts are not equal lengths, so you have to carry 2 spares if you want to be prepared. X and Sport owners only need to carry 1 shaft to get them home from a trail-fail.

so your saying rubi shafts are different from all the other jeeps despite them both having 44s?

what he is saying is the left and right shafts in the rubi axle are different lengths....they are also different then older 44's...you cannot use another 44 shaft in a jk rubi axle, if thats what you are thinking

Right on, that's what I was looking for to put me over the edge. I've got a 550 mile round trip and 4 days on the Rubicon in July and the only thing that worries me is breaking a rear shaft. Looks like I'll get a set of cro-mo's.

If I remember right, the Rubi shafts are 32 spline and non-Rubi shafts are 30 spline.

We broke the passenger side rear, a Superior EV52 that is, so chro mos are still no guarantee.

And the lengths should be the same it is the spline count that varies.
Not true at all. Due to the proprietary Rubi locker, the shafts are unequal lengths. The X or Sport models do not suffer this stupid design. Makes carrying trail spares a PITA.

I bent/broke a few Superior chomo shafts before getting D60s. Nothing is unbreakable.
