Good luck Ahmad. Can't wait to see the completion of your project.

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.

 

Thanks!

That is a rediculous gearing top speed haha

No just like you I couldn't get info from DSS. They are not custom for my car. I will be taking measurements and everything for the benefit of everyone else. Getrag is different than the m215. People are going mid/low 9s on a m215 so no need for a Getrag. The big boys are running 8.8 conversion kits
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.

 

Tnx bud

 

Sure you can go that route if you like. I was just saying what I plan on starting with. "custom" axles cost more according to DSS so length does matter.

 

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.

 

This is why I bought things to resolve all these questions. People have been saying this and that for years. I will find out. And axles should be different lengths for different width cars don't you think? My CLK probably has different length axles. You have a 300CE? You might have same axles as me. How much power are you making? If I get measurements everyone will benefit. I don't think E55 axles will be same length as 300CE. Once I get everything I will answer the questions I can. Until then its just speculation like it has been for years. I think the hubs may be the tough part, the rest I think I can handle.

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

 

Keep

That sucks, was hoping you would have found a cheap and innovative solution. Thanks for pioneering the way for all of us.

 

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.

 

3.06 or 3.23 for the m113k with a 26" tall tire would do wonders.

 

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 ***!!!
Thanks,

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.

 

This is true....hmmmm....

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.
