I think mike's application falls out of the suggested guidelines for indestructible.

Good point.

But I won't say anything.

plenty of guys on 44's that dont brake those.  And with way more HP. 
 I would think the pinion at the yoke would have broke first.   Or maybe the 1350 joint at the axle end.
I think he got a defective one.

Burn it.

I'd tend to agree. And also agreed on what the weak points SHOULD be, much further up the chain from the axles shafts.

Same I was sure it had to be the spider gear welds. Upgrade to 300m doesn't sound like a bad idea though. Might try and get a spool with that upgrade?

i was surprised i was able to use 2 telescoping magnates and with some jiggling the chunk of spline slid out of the carrier though the tube.  Carrier does not appear to be f'd just the seal.  I didn't pull the diff cause no point in 2x work.  it got a spindle and hub thrown back on and stuck in the trailer. 


Ill look at spool costs.  id say the weak link is still the stock rusty front 84 GMC drive shaft with one semi dry original 1350 ujoint that was in said drive shaft when i picked it up out of the scrap pile lol.  it is 5.38 times less ass there and really only 300hp on a cold day.  A ring gear running backwards or the shafts still have to be the weak link.


300M and maybe a spool will be the fix.  needed a fluid change and a diff cover bolt guard is near in the future

for what i have done with KRTs in the rocks, i dont think it was defective.  anger and HP could not break them at least 2X

237 for a yukon 4.56 and up isnt terible.  would get rid of the spacer i have now.

email into RCV.

their live chat is not so live.


probably have a 4130 shaft warrantied- either sell the set or keep as spare.  Then just get another full 300M set because no sense in having 3 spare weak shafts.

any more air videos of 572 haha.  thats a fun rock jump hill


i like the one josh got of 4 wheel roosts though two gears launch

[etk300ex]

that ledge looks so small on video

[M4wdFab]

its only like 4'

Called RCV- they said it broke the way they break. 

287$ option to upgrade the shaft to 300M, or free warranty of the 4130 shaft.


the upgraded 300M kit has 300M CV's so ill just warranty the shaft, and get another full set of 300M RCVs. 



he was very supprised to hear 300hp and 44" tires broke a shaft.  same response copper fab gave me when i was the only guy to break one of there sway bars so far.  Cant wait to break a solid knuckle next!
