Pitched Axle (?)

@Bill_Cochrane I don't understand what a pitched axle is, much less it's significance. So I hope someone answers this because I've searched the web and come on discussions of splines, angle of pitch 30 degrees vs 45 degrees, stress, torsion, through hardening vs induction hardening, etc.. Perhaps the best bet would be to call Al-Ko, if that's the correct manufacturer of the T@B axles and ask them. I tried asking nüCamp but didn't push to speak with an engineer type person because I'm guessing I wouldn't understand the language being used and didn't want to waste anyone's time. All I was told was it provided higher ground clearance. But I'm not ashamed to waste forum members' time if anyone is up to the challenge of using simple English for me.

Ok, thanks @pthomas745, I remember that sentence from @hunter99 which sent me down the world wide rabbit hole again  looking at diagrams, rereading it, trying to rearrange the words to make sense. It's ok, I withdraw my question and will take as gospel that a pitched axle is a good thing and will simply appreciate the fact that our Outback has one.  I can't speak for @Bill_Cochrane though, but hope he as enough grasp of auto mechanics to understand this. 

Thanks @jkjenn That clearance actually comes in handy in driveways, especially our own.

Some of the difference, the first one like mention is the angle of the trailing arm witch gives a couple more inch ( do not know how much exactly).  But it also come as a 2200 pounds axle and the cross member tube is also square instead of roundish and I beleive much thicker.

2200 pounds, mean bigger bearing, witch is good, much more durable in the long run.  But also bring a suspension that is much more stiff, creating a lot of bouncing Witch is not that good.

An other point, is the higher ground clearance brings more turbulence under the trailer and behind it, reducing or afecting aerodynamics, witch could afet drag and fuell efficiency.

one thing, I know for a fact that the T@G outback axle is rated at 2200 pounds, I saw my sticker, not sure about the regular T@G and even less knowladgable about the T@B's..

A pitched axle is a thing that made me more likely to purchase Michelle, my 2017 Outback.

Hope this helps.

Higher ground clearance, @Bill_Cochrane  Sounded like a good idea since we foresaw doing at least a little off roading.  (Turned out to be handy on the way to Chaco Canyon NHP.)

. . . explanation would benefit both the members and future buyers about the advantages of having a pitched axle.
. . . Thinking of a clock really does not help me and I have no idea where a trailing arm would be

Believe, today new built 320, 360, 400 are only available with the Boondock 'Package' which includes the greater ground clearance "pitched" axle.

This table explains the older standard and vs. 'pitched' Boondock difference.


Boondock (Outback) "pitched" has ~ 5.2 more inches than the original standard (lower enter step) model.
