I'm pretty sure the axle width is the same between the XJ, TJ and KJ. If you were thinking of getting a set of those JK Rubicon axles that Mopar performance sells to do an axle swap, they are at least 5 inches wider than a standard TJ axle. Plus the bolt pattern is different. TJ Rubicon axles should fit just fine though, that's what JJ was going to use originally for his build.
I believe the mounts on the JK axles are different also compared to TJ or XJ axles so new mounts would need to be welded on also.Gears and lockers are super big bucks for the JK axles though.
The couple of articles I have read basically said the only mounts that needed to be moved were the spring perches. They said the control arm mounts were about half to one inch offset and that adjustable arms with enough flex in the joint could make up the difference. And they come with 4.10 gears and the electric lockers installed already.
To bad most adjustable arms do not have the reqiured flex(which would actually limit articualtion if they happen to have enough) so all the mounts would need to be moved.You will also need lower gears then 4.10's unless you are staying with 31" tires but doing a SFA swap why stay with 31" tires?
Just went to JP magazine and read the article on the JK axles. I'm thinking they may be a real good candidate for the SAS on the liberty.
Pros:
about $1600 for the front and $1350 for the rear - $3000 for a brand new set of D44's right out of the box
built with the standard rubicon e-lockers, all you need is to wire em up.
They come with the brake components
JP says some of the components are heftier than the TJ's 44, higher spline count etc.
Wider than the TJ's 44 by 1-2"
Cons:
Limited availability of different gear sets, right now you can only buy with 4:10, but 4:88 and 5:13 are available after market. That will add to the cost to have the new gears setup, probably about $300-$500.
Someone designing a SAS kit would probably be wise to use this as a starting point for the kit.
Marty, I'd be glad to be the test vehicle
