His comment was that the  D60 while a great axle  the pinion would not be strong enough to handle the huge torque load of the 10:1 reduction from the Atlas.... Anyone in the market for a Kidney?  Ok  just kidding  for the treadlightly approach I have the  current uprated 44s will do.


This is one I had not heard.  I run a Advance Adapter Rubicrawler on my LJ, with twin sticks, This gives me four crawl ratios:

-1:1
-2.72
-4:1
-10.88:1

My axles are dana 44 front and rear.  You definitely need to be careful at 10.88:1, but I've had no issues thus far.  The only real problem is you have to bump it out of gear to stop.  If you push on the brakes while at that ratio they won't stop the vehicle.  The good news is it will idle up a 45 degree incline.

From what Advanced  tells me the deep reduction  gearing  is not ment to take any kind of big HP, just idle or a bit above.  I bet you are running an automatic?  I can see the brakes being nearly useless  in the deep reduction.  The unit I am looking at is a
1:1
2.72:1
3.80:1
10.34:1

Advanced  dosent seem to have an issue with the 44 but would prefer a stronger  ring pinion... Like everything  it is all in how you use it.  Drive smart and the equipment will last a long time.

Love to see you rig in action

Something else with the chaos philosophy that I like is  they  build  in such a way that the engine is the weakest link.  That is to say  if the engine makes 500hp and 500 torques, the  drive line will handle 600/600.  

This sounds like a great way to blow up your engine if you ask me. I'd rather break a $30 u joint then redline the engine and throw a rod if something goes wrong.

But I'm just a simple man in an LJ on 33s with no long arms and no truck night victory.

James,
You missed the point. If the hardware behind the engine is stronger than what the engine can produce chances are you will not break that u joint... hence continue to wheel happy.

But then again  if you operate as stated doesn't matter how it is built...your going to break it.

All I know is, at some point, something is going to break. I'd want the engine to be the last thing that breaks. I understand why they did it that way, I just have a philosophical difference on it.

If you hit a bump and mash the skinny pedal one time (which happens no matter how careful you are), I'd much rather replace an axle shaft or a u joint then the engine.

Definitely an automatic and I'm very conscious of cause and effect.  That said, the skinny pedal is treated respectfully and engine speed is kept to a minimum.

Not yet.  We won't be making EJS anymore either.

So you're swapping the suspension and possibly selling it?  I want that EVO kit....one day I'll get it.
