What diffs in Commander?

What diffs are in the new Commander? I heard the 8.25 in back but what's up front? I know it's IFS.

Only info I was able to find:
Standard:
3.07 axle ratio
Axles, 200mm front; 213mm rear

Offroad group has 3.55.

If it is the 8.25 thats the same as the Liberty...Would make sense.

Just saw some conflicting info:
3.07:1 - 3.7-L engine;
3.73:1 - 4.7-L engine

www.xkjeeps.com needs to get their facts straight.

Rear axle: 8.3 in. (213 mm) Sounds like the 8.25.

The rear looks like an 8.25 Hmmm...I wonder if AEV will offer a pair of D60s in the near future.



What is wrong with this picture? I need to see the rear end of one on the lot...

The tranny behind the V-6 makes them use 3.07 gears because the overdrive isn't a .65 like most overdrives are.

Exactly and first gear is something like 4:1 which is very low for an auto-tranny.

However, 8.25 axle with a hemi v-8 towing 7500lbs would make me a little concerned.

I highly doubt it's actually an 8.25, at least I hope not, otherwise we may see more problems with it then the D35 TJ's, ZJ's, and XJ's.

Ok so how is this axel compared with Dana 35/44. Looks like newer GC and the commander have the same type of axel.

Hmm... Dana 44 strength, but C-Clipped.

That basically sums up the 8.25. It looks like it could be one, but that diff cover is really making it hard to tell.

The Front is a Dana 44 IFS. Someone (that knows what they're talking about) correct me if I'm wrong here. I think I'm right though...

I read on cars.com that the rear is a "live Dana 44."
