I was wondering did you verify the DSS axles fit. Are they custom for your app. I talked to them and could not get any info from them to see what was the same. I want to do a driveshaft and diff and axles in the future. I was going to start comparing parts to the lx cars. I was looking at the getrag rear ends and man they are cheap. They are like 1400 with limited slip and axles already for the lx cars. Pick your gear ratio.

Agreed, you should measure the axles, and check the wheel hub side spline count as they may be different.
Also, the getrag 226mm Diff's will not work. They have completely different mounting setup and you would need custom driveshaft.

For Mthis
1st 43
2nd 67
3rd 99
4th 139
5th 190
6th 232
7th 261
That is a rediculous gearing top speed haha

I can only measure it when I have it in hand lol. I hate waiting and it seems like the quickest way for me to get data is by myself (also most expensive way haha). The spline count is definitely different than my car, that is the main reason I am doing the swap. I have broken the hub splined end off my axles at least 5 times. After I get everything then we will know if it will also fit an E55. No more rumors

I want a driveshaft anyways. I could just do a driveshaft and axles but for one off custom stuff I could buy a new diff and start from there. Then it is only the wheel hub splines that I have to worry about. Length does not matter. That is per order. But machining new splines and adapters etc the price more than doubles for the axles and driveshafts. Making the differential fit in my car is not that hard. At most a custom rear cover with mount locations. Fairly straight forward piece of plate aluminum drilled to the rear cover pattern and relieved for the ring gear.

Thanks! 
I don't get the parts until the end of next week but I hope this all works out. I will be out of the country the following weekend but when I get back its full steam ahead on this project
I will have to look up the gearing in the C63 since its different than the 722.6 I will text you the numbers. What is your rev limit as that is important factor

My understanding was that the length was not the issue but machining new splines. Or in the case of the driveshaft it was the adapter ring that bolts to the flanges for their driveshaft to bolt up to. We can easily swap the transmission flange to a chrysler one. I would just go with the Mercedes 215 gear box also but for the cost and then adding a quaife and then gears the getrag looks like a good deal. Especially starting with custom parts. I am interested in any solution if it does not cost more than a 3-4 thousand. I know if I launched my car hard stuff would break. It is much weaker than what all you v8 cars are running.

Btw have you checked DSS price on custom axles? And they dont guarantee it wont break. The price may shock you

My differential is a little narrower than yours. and my axles are longer. I do not have traction control but the cars like mine that do have shorter axles that are the same length as yours. I have a half shaft out of a clk like yours and it would work on the wheel flange. I can actually swap the whole wheel carrier to in to my car. Basically same parts with the addition of the speed sensors. I looked into swapping in your diff or one out of a c32 for the better ratios, same housing. I measured everything and I think it would bolt in. I actually bolted up a differential once without the axles. I also bolted in a 215mm housing to see. Yes the axles are different lengths on the w211 chassis for sure.
I am making low 400 whp and about the same torque. I am hoping to get closer to 500 whp with some stuff I am working on with a little more boost and e85 this year. I might spray it to in the future. If I do something with my driveline I just do not want to do it again.
I talked to DSS about the prices and yes they are shocking for full custom but they told me that if I used an existing pattern that the prices were pretty much the same as the bolt on stuff for the LX cars. I do a lot of work with chrysler stuff doing hemi swaps with the 722.6 and standalone control. I have a few customers now running the DSS driveshafts for their applications on a one off basis for length but the standard adapters. Unfortunately the work I do is more sales and tcu setup so I have not had the parts in my hands to compare.
I am anxious to see what you find.

Well the verdict is in. the dss srt axles which come with hubs will not work on our cars since the hub end is different. The srt m215 has different mounting points and use a 210 E55 cover and should actually bolt right into a 210 E55 but not a 211. The rear cover from a 211 E55 will swap over though. But the casing still has different mounting points. My clk has different rear cover mounting points than both the e and srt buy that doesn't mean I'm giving up. Should hopefully have custom axles, hubs, diff flanges, and either rear cover or custom mounts within a month or so for my car. Then its time for a eurocharged tcu tune and to head to the track and lift tire lol

The two diff's used in 55K cars are the Mettinger M210( 02,03) cars and M215( 03+). The number indicating the ring gear diameter. A variant of M215 is used in the SRT-8 ( slightly different casing for mounting tabs, but internally identical). The M210 is used in RT LX cars.
The M215 has a 29 spline axle side( 30 on the diff side) and not sure on the wheel hub side. The axles look very similar in length to SRT-8 Axles
The ring gear options for the diff include,
2.62,2.82, 3.06( stock MB and Chrysler ratios)
3.23, 3.55 ( Richmond R&P sets)
All of the above are compatible in the M215mm pumpkin housing
DriveShaft Shop make axles and hubs for 1000hp plus that I imagine are pretty close to compatible, but woul just need sombody to measure
In order for any of these to work you need to program the EGS52 TCM for the correct control ratio.( jerry can do this)
I will be installing my 3.06 sometime soon and will try to do a full documentation of the process.

Will these also work on a R129 M119 500SL (1997) 2.56 stock

Stock auto 5.0's back in the day would get a .8-1.1 sec improvement in ET's with gear change alone and sticky tires. Get ready for some serious improvement in acceleration.
I used to have a daily driver supercharged auto with 4.10's, higher stall convertor and it was a blast on the street. Traction will be your challenge.

So they do make a gear set for a R129 M119 / 1997 SL500? If so, do you have to tune the trans as well and who can I contact to get this done/ buy the parts from?
Man, a full sec, i would love to ram that up the *** of another forum know it all's ***!!!

I'd love to do the 2.82 swap but did I read somewhere correctly that our TCU needs to be programmed afterwards? That is the bit that sucks for me having to mess around with contacting tuners especially in this country (UK)...

I believe you could just ship your TCU to Eurocharged and they would program it and then send it back to you.

or anywhere for that matter, all 96+ SL must have the ECU removed to be tuned, they dont have a chip like the older ones from what I have read, so I would do, plus they will knock off the 155 mph speed limiter, but do they make a 2.82 for the R129? if they do, do they make an even higher one "numerically" of course? I think a 3.27 from a 2.56 would give some nice torque multiplication or even 3.55, I mean **** I hit 155mph in 4th gear and still have rpm to spare, it would be nice to be able to use all of 5th gear, Imagine the speeds you could get to w/ that gearing, like 175 at least, our cars drag coeifficient is one of the lowest ever made, that includes modern 2012 stuff like Ferraris and Vettes.

Truth be told, I'd prefer to change the gearing, than add more boost. I love short gearing but dislike crazy fast top end speed, so this would be perfect for me.
