I thought GM trucks went metric 2011-ish.

GM did, but its a different metric. So now you have
Ford 8x170
GM 2011+ 8x180 or 8x210 (duallys)
Dodge/Ram 8x6.5 (8x165.1)
Its really stupid because 8x6.5 is more than capable of carrying the torque, and 170 is so marginally different from 165.1 that it wasn't worth changing. At least going from 165.1 to 210 gives you enough room for a bigger bearing or something.

I'll keep my eye on this thread. I have seen 6Ds listed for $300-$600 on car-parts.com or whatnot and had me on the fence about scooping some up but I am not in that territory of mods yet. I try to keep up with the thread on pirate about 05+ SD 60s and saw that these axles will take shafts from the f450s and f550s 
1550 joints BTW

I thought only the super 60 (10" ring gear) from the f450/f550s can use those 1550 ujoints? And the inner Cs and Knuckles are much larger than the regular 05-up SD 60? I know the unit bearings are different

Fawk no! Keep hoarding the small u-joint 78-79 dana 60s
This is what I am finding on pirate:
(replacement axle shafts, ford oem)
2005-13 Ford F250 Super Duty Truck excluding Wide Track Axle Ford OEM FC3Z-3220-A, FC3Z-3220-B
2005-13 Ford F350 Super Duty Truck excluding Wide Track Axle Ford OEM FC3Z-3220-A, FC3Z-3220-B
2005-13 Ford F450 Truck excluding Wide Track Axle Ford OEM FC3Z-3220-A, FC3Z-3220-B
2005-13 Ford F550 Truck excluding Wide Track Axle Ford OEM FC3Z-3220-A, FC3Z-3220-B
Sounds like there may also have to be some juggling of the brakes/lockout but one guy has ordered that 1550 shafts and will compare them to his 05+SD 60 shafts when he gets a chance

I honestly think they're 'the wave of the future'. Cheaper, stronger, newer. We're working on swap kits for 60-70's trucks. There are a few out there for 80-96 fords that are in the $2500-4000 range. 'Toughest' thing about it seems to be the RA's.

I agree but not until all the kingpin and early BJ axles are used up.The only problem I see is that when they are the only choice psd cases will be boat anchors.Ive passed on several in the 3-400 range in the past.Might need to start rethinking that.

17s are the new 15s anyway. Your options for tires with 17s are endless!

from what I have seen, all the 05+ axles have the larger knuckles.
The best thing about them, is to run super beef stubs:

I think I would go with the newer also. I wouldn't mind linking the front. It would be a while. I will pick some up if I come across the right deal. If nothing else, to sit on them till I'm ready.

Let me say that those shafts aren't cheap. But if you want ultimate beef, those stubs with rockwell rcv bells and 40/47 spline shafts will bring it.

Ya I don't need that beefy but it looks like they are stronger stock then a king pin axle

Ball joints are fine. I've seen king pins break. Besides the ball joints are designed for several ton trucks hauling loads. A 3500 lb jeep isn't gonna kill them fast

I agree. But hate to break it to ppl that think they have a 3500lb 1 ton jeep, they're likely off by a half ton.

My xj is around 4000 (I think haven't had it on a scale in a while) I'd like to have a rig that is mostly tube hope to have around the same weight as my Jeep now, minus wheels tires and axles I realize that will be probably 1000-1500 lbs
