I've been researching gear swaps and LSDs for the past three days and I just pulled the trigger on a scrapyard SL65 unit. I want to confirm that this is the right unit that will bolt into our E55s and that it has the 2.82 gears.

Here's the eBay listing:

it will not fit the w211 E55

Does it at least have the 215mm 2.82 R&P? That's really what I'm after. I am going to get a Wavetrac unit and want to go with the 2.82s at the same time.

is this the one I want:

This is starting to make my brain hurt. I think I'm going to get the wavetrac and just stick with the 2.65s for now.

No R230 diff casing is going to bolt on to a W211

if you just want the gears you can get them from one of the dodge forums people upgrading their 2.82 gears -- they are supposed to fit without issue -- save you a few bucks -- do a search on dodge srt gears

Yes, that's where I started. No luck yet.

I found this in another thread and can not validate if its accurate but the poster said he was running an sl65 diff and it fits -- so I am confused also -- maybe the ear fin/cover needs to be swapped but it should be "easy" to confirm mounting bolts are the same -- ?????


Axle Ratios:
SL55: 2,82
E55 (Sedan and Wagon): 2,65
CLS55: 2,65
CLS63: 2,82
SL63: 3,06
SL65 BS: 3,06
E63 (Sedan and Wagon): 2,82
S55 supercharged: 2,65
CL55 supercharged: 2,65


There are 2 different families of rear axles mouted in E55/SL55/CLS55:
Up to 2004 it is HAG210-family (screwed drive shafts on the left and the right) and later it is HAG215-familiy (plugged drive shafts).


Mounting points of rear axles are the same in R230, W211 and C219.
W203, C209 and R171 have different mounting points and the do not fit in W211.
Same is with W220, C215 and W240.
