Alloy chromoly axle shafts

Took my wheels off to attempt to take the spacers off and I came across this. Couldn't get the spacers off so what you see is all I've seen. Could it be possible that the PO put in chromoly axles? If so how do I verify that's what they are. And what are the benefits of a chromoly axle shaft?

They are a different hardness than the stock steel shafts, and are ductile in a different way. They are much harder to snap in half or to break the ears that hold the universal joint.

Alloy USA shafts are made in India, I think. Not the best, but still a huge upgrade from stock.

Please note that it could just be that single outer stub axle. You have four shafts on the front axle, the long inner on the passenger side, the short inner on the driver side, and the two stubs that connect to the wheels via a universal joint. The Alloy USA shafts are anodized black, the stock steel ones are bare, gray-silver steel - or perhaps brown with rust, heh, heh, heh...

You have to remove them partially to see what you actually have.

Lucky you! I just paid nearly $600 for a set of these!

Here is the home page with the ad blurb to explain it to you. Remember, these guys are selling you something, but it happens to be a genuinely good product in this case.

That picture is of the rear axle shaft, no telling what shafts are in the front axle. It's also much harder to tell if the front shafts have been upgraded since there is no sticker on them like there is on the rear shafts.

The simple answer is alloy axle shafts are stronger and much harder to break.

Thanks guys! I've got all kinds of questions about this set up and you guys are comin through as always with the awesome info and insight!

Next question:
Are the Rough Country 2.2 (long travel?) shocks good? There is only a couple to three inches on the bottom which is why I think they may be long travel shocks. Or possibly too big for the 4" lift that's on it. Not sure. I'll post a picture tomorrow when there is light.

The 2.2s are actually the softer of the two main ones. The 2.0s are more sporty and firm. The 2.2 shocks are more plush, if you can call anything about a jeep suspension "plush", heh, heh, heh...

Actually, I might have that backwards. But if I do, no doubt someone will come in and correct me. ;-)

There's nothing "plush" about these shocks! Haha

I was just curious as to what people's opinions are about them. I'm a fan of the zone shocks but this is the first time I've ran with rough country.

Disregard all. I just found a thread talking about them. I'm gonna change them eventually.

I do however have a follow on question. If I have the long arm 4" lift from RC. With the 4" shocks from zone be a hindrance to the functionality of a long arm lift? It's my dd so I don't do any crazy off-road. Just a trail here and there.
