Open Discussion - Front solid axle conversion

Question: Say you do SAS with a D44, done up right and run 35s, what gears would you put in and how would you regear the rear axle?!? Also assuming someone as myself has QDII which would render itself useless, how would you get the computer to act right when wheeling?

[Matt]

Id put a D44 in the rear as well.

Us QDII guys would be in trouble. A 2010 hemi QTII would be ideal..

From what Ive seen a good D44 built right, which it should be is around 1500-2k??? so times that by 2?? Is there anyway to keep the rear axle? Or swap out the 12 bolt for a 10 bolt and lock it. but then still no gears..?? Then what about Tcase?? And computer? Seems like 10K+ easily..

[Matt]

Find a wrecked 2wd xk with a d44 rear and use that. Infinitely more gearing/carrier options.

Tcase and trans are fine. Computer is fine (for qti and qtii)

Yes it will be a very expensive build.... youre not gonna SAS a commander for cheap. Done smart, I think it would be under 10k though.

Consider superlift+rcv axles+gears = $6ish... and thats theoretical since we can't regear... so its not completely unreasonable.

When I added up the cost to build MY XK up with a super lift and all the extras I came to 5K and it still was IFS. This is one of the reasons I went out an bought a 2000 Grand Cherokee with a SFA. When I beat the crap out of this and am ready for a change I will sell the WJ and start the buildup on the XK. But in the mean time I am going to start looking for the axles. A D44 front and back would allow you to lock and gear how every you wanted. An additional item on my wish list is a long arm suspension (after a gas tank relocation). This would take the XK to a completely different level.

[Matt]

Hmmmmm, would probably have to disable the stability control due to steering angle differences (like putting a wk rack in an xk lol)

[06JeepXKHEMI]

So you'd be able to use the tcase we have and transmission, and swap out a QTII or QTI computer? Im just trying to justify, besides the obvious gain in flexing the front and coolness factor, of this swap compared to modified SL w/RCVs.. I have to imagine gears will come sooner than later, but running 33s proves to be alright..

[Matt]

Dont bet on having a lot of gear options. Our axles had a limited run and I doubt will see any significant aftermarket support.

SAS will give us gearing options, the necessary amount of lift to properly run 35s and the ability to take these vehicles to the next level offroad. A modified superlift on 35s isnt going to do much more than a modified superlift on 33-34s. In both cases our front suspension travel sucks.

Not to mention the cost of replacing our crappy steering racks all the time lol.

I think QDII guys would need to swap in a QTII computer. Not sure how we'd solve the stability control issue but id imagine the first person to do this could get AEV on board to help. .. their module with the proper setting will do it

[Matt]

With all that said ill probably never SAS my xk..... theres just not enough wheeling around me to make use of it. I can have a modified superlift installed in a weekend and be done with it.

If I lived out West, it'd be in my crosshairs.

So essentially, wouldnt a 2wd XK be ideal?? I see your point on the advantages now, I guess if you bout axles and built them over time and addressed SC and computer issues the swap wouldnt be as bad.. Assuming a 8" lift and long arms would be the set up..?
