Ok, I am really considering putting D60's in my JK. But I have a few questions, that I can't find answers for with search.

1. Are the axles full width, or are they shorter for the JK?

2. If they are shorter, would I be able to cut the tubes and reweld the ends?

 

I believe that they add a bit to the width, but they are definately not full width. You could likely order a custom width, but the price might be ever scarier than what it usaully is.

 

They are almost always wider... seeing as they are almost always from 3/4-1 ton pickups Thus they are FULL WIDTH

And if you want stock width, you can cut them down and order custom shafts

 

I believe that he is talking about ordering a custom set for the JK. They are built to bolt in and are not from a truck. It is possible to use junkyard axles, but there are a lot of electrical problem going that route. If that is the case, they are not going to be as wide a the front of a dually

 

Full width........ How wide is full width?
The term full width is used a lot now days, but what does it really mean!!!
When building a CJ, full width meant 63"-67" wide, the width of a stock full size truck axle. The stock CJ track is 56" wide if you have a "wide track" CJ, so going to a 63"-67" axle is a huge difference.

Now lets fast forward a few years, 2007..... the JK was born. Stock width for a JK is 65.5" wide, so............ does that make the JK a "full width" vehicle? If not how wide would "full width" be considered on a JK?

^ damn... those axles is sexy

 

Thanks for those info. You're really going hardcore when you put those on your JK!!

 

Maybe a dumb question, what makes the fronts so much more than the rears?

I understand there are extra parts there, but $3000 worth?

 

Inner and outer Knuckles, ball joints, completely different shafts 2 more at that, spindles, brakes, locking hubs, u-joints, bearings, steering arms, studs......yeah its 3k worth. Its not that these things are designed in regular autoCAD, Im sure they are using a $10k+ program similar of Solidworks that stresses these parts to find weak links. When you get in the engineering aspect of things, there's a little bit of coin in there for R&D also. These are a whole different animal. Rears don't take nearly the same amount of design other than the housing itself.
