sorry doc no it isn't,, doing some machine work and some welding to fit the 346 and or the 373 into our case. jim

 

I am up to date...just got off the phone with Rudy. When you figure it out....I'm in....lol

 

Ooo 2.82:1

 

You know where I can find a 2.82:1 ? That would be a lot better than the stock 3.25 with a granny low six speed.

 

Some mb in mid 90's had a 2.82, would b perfect for our 6 spd over the 3.27

 

it not just finding the gear set ,,it's finding a gear set that will fit into our differential housing and there are none that is why i am machining and welding ,, maybe if i make a spacer weld it in i i could maybe get a 2.82 to fit and work with all our factory equipment ,,, after i finish the ones i am now working with,
jim

 

The early 2000's w220 rearend from pics looks almost just like ours, they have a 2.65 and 2.82

 

We have checked about 75 differentials and have found a few that fit, ALMOST and to make that fit we have to machine off 50 to 150 thousands from the center section or add a machined spacer then move the pinon gear to match, there are none that is a bolt in so far and yes we checked the w220's and a lot more.
At J S Benz high performance shop for Mercedes,, i have access to a lot of parts and different years of Mercedes, along with Rudy we are working on it.
with a little modification we could put a sub frame from a Mercedes into our crossfire but then we have to change the hubs,, and calibers , but it would work ,, this could get us a factory posi at almost no cost. if we find the right one that bolts up into the crossfire bolt pattern I don't post much about this because it may not work . just on this subject i have received 6 pm's for info, when i get it to fit either the gear set or the sub frame i will post it. jim

 

And we all thank you for the work.
How about these 2 rearends, one is from XFire, can you guess what other is from?

Do you have access to differential from a 06 charger, 2.7, 3.5 and 5.7 to compare side by side?

 

yes on the charger the internal parts will not inter change and the charger housing nose mount it different. if I remember ,,,it was a year ago that i did the charger stuff,, you can put the Challenger rear in , but have to change the mounting bolt placement ,,hubs brakes and axles. i am trying to make so there is little to no extra work for the swap.

if you have found something that we missed please let me know we are all in the learn mode. jim

 

When I was looking at the differnt charger rearends, the rearend from the 06 with the 2.7 or 3.5 looked identical, the 10 and newer is differnt but in 06 they made 3 differnt sizes of rearends in 06.
Like the one I posted pics earlier one is upside down, but the casing between the 06 3.5 (I think it is the 3.5 not the 2.7) compared to the XFIRE looks 100% identical cover, mounting and how shafts mounts, just different oil drain and fill holes. probably have different spline axles, trying to research. But the 06 charger has 4 or 5 different ratios including 3.90, 3.64 and a 2.82.
There are several different.
Take a quick look 06 charger 3.5l and tell me if that looks like the one u already looked at and ruled out.

 

can't br sure as that was last year.. but i can say we only looked at two housing from the chargers,, not even sure what year they were just know they were older year they could have been 06 if you have one check and see if it does fit into a crossfire maybe you found something great and maybe the wave trac will fit in it. let me know asap what you find out. thanks jim

 

I seen one in a salvage yard last fall that made me originally think about it, if would have to buy one off eBay or buy one in salvage yard if I can find another one

 

What year Challengers? Couldn't you just use the Challenger or Charger diff and have some custom axles made with inners for the challenger or charger diff and outters to fit the crossfire?
If its just one mounting hole that seems easily fixable.

 

yes you could ,but what i am ytrying to do is find the parts that would interchange into a crossfire. then mary, or joe or whoever wanted a different ratio could just order the parts,, put it together and go down the road,, as far as having axles made that is not as simple as you think... years ago it was easy, today you have speed sensors built in and your abs os if i can find what firs wouldn't it be better than everyone for themselves to get what ever they can JIM

 

So what year challenger and charger are we talking?

 

the 2010 2011 2012 with the gateleg and 391 posi. it is not a fit right in , the cost is going to be around $2000.00 the diff alone is $1000.00

 

Thanks for the info! Our wavetrac isn't cutting it, we need a different option. Switching out the diff is our only option. Budget isn't a huge concern. I'll share anything we learn, but at least I have a good starting point.
