Anyone Broken an RCV ?

About to upgrade my axles and I am debating between ten chromoly or RCV . I have a hp30 and currently am running 36" Iroks. Wondering if anyone has broken an RCV shaft? If so what broke, how did it break and what size tires where you running?

There is a thread over on jeep forum about this in the TJ tech.

RCVs are remarkably strong.
However running 36s on a D30 is nearing the maximum size.

From what I have read the RCV will likely be fine on 36's but the ring and pinion even on a HP is where the failure point will move to.

This I know, I would run 35's but the Iroks don't come in that size. They do great in our trails around here!

That's what I have read as well, just looking for someone with first hand experience. I am pretty easy when I wheel, but the 36's will demolish u joints if your looking for traction and it gets it lol.

I have the first set of RCV's ever made(back when they were a LONGFIELD exclusive) On a D44 and 36 Iroks. NO problems with them at all and would use them on any rig I built.

RCVs are strong but so are aftermarket hardened alloy axle shafts that are half the cost. I run some pretty tough trails that have broken my TJ's factory shafts but once they were replaced with hardened alloy shafts, no more breakages.

I run RCV axle shafts on my dana 30 and I'm running 37" Goodyear MTRs and I haven't broken them yet. I wheel my TJ pretty hard here in Colorado ahd haven't had an issue at all. Not to mention the warranty that comes with them. If you ever break one it's no questions asked replacement. It's worth it in my opinion.

They dont ride as smooth and there stronger than all of the bigger name aftermarket shafts that I tested, I got to break a few sets on the LONGFIELD axle breaking machine.
