Outer Limits 4x4 Board

Has anybody setup with 4.11's and maintained the Rotoflex couplings?

Just wondering if it bolts up as usual with the bigger pinion nut, or if machining is required, or if it cant be done.

I've been running uni-uni shafts on the rear, but don't pound the truck like I used to and was hoping to go back to the rotoflex to reduce the NVH on the road.

TIA for any help

Never touched D2, but assuming they're the same as D1, that'd be a no, as the pinion is different, it has the spigot for the cuopling potruding, which aftermarket, 4.11's wouldn't

Keep it as it is, when our Mogs arrive you'll be playing hard

The D2 diff is pretty much the same as the D1/RRC etc diff. Thats a bugger.

Gonzo, I'm trying to finish this atm to keep up with the mogs. Wires and plumming left to do.

Hi there are a number of aftermarket 4.11 r&p, (not to be confused with 4.1) as noted some have the larger (Salisbury size) nut others including ours use the stock nut which can be used with rotoflex spigot.

Excellent, thanks for this Dave!

The one that I have in (Dana manufacture from what I'm told) seems to have the big Salisbury nut then, though I bought a spare 4.11 from you in the event that I broke a CW/P. This pic is the spare that I've got, and to just confirm that this one will take the rotoflex joint onto it?

Interestingly, it is still a different end to the OE Disco2 pinion.

Slunnie...

The rotoflex WONT survive a 4" lift...

2" kills them quick enough... 4" will obliterate it.

Gday TeamRaider,

The great thing about the Disco2 is that as you increase lift there is minimal, if any change in the pinion to tailshaft angle as the geometry always has the pinion pointing at the transfer case. This is unlike the more traditional Rovers where the pinion angle remains flat or drops, which increases the angle through the rotoflex causing failures.

I recall doing a survery etc a while ago with D2Au, and it seemed that for Disco2's the big thing that kills rotoflex's is big traction tyres and my guess is also shock loading.

my heart fell out my A#R# team Raider when you said that I was quickly trying think of an excuse to tell the missus to why I need a new shaft

having said that one will come later or sooner if Slunnies is up for sale
