Thankss,, but unfortunately i can’t do that with my TCU/EGS51....

pics of the massive axles!!! bolts are being replaced with ARP stainless bolts

Nice!!! Can't wait to install mine

Its been forever man..... i feel like im related to you now!! lol

Definitely very interested in this kit. Whats the secret handshake behind purchasing one of these kits.

stockC43

Me too. Is it possible to use stock 209 55 axles and hubs with this diff swap in a 202-208? Are they any larger if they fit? I don't plan on doing bumper stands but I will be 200-250 hp more than a stock c43

2PRECISE

in terms of what it fits.... i dont know.... the axles are much larger then stock. as for selling a kit with stock axles.... have to discuss it with DSS, but if i remember correctly spline count was to small and didnt bother.

stockC43

That's what I figured. Figured it was worth checking though to save a few $ if it was stronger than a stock 202-208. Well, time to save for dss axles, a 209 diff and a LSD. I told myself I wouldn't put that much money into my 202.

2PRECISE

yes... this kit is bullet proof, unfortuneately the parts are expensive.

reason being, u need to buy lots of parts from dealership to install this kit.

2PRECISE

lol no secret handshake... the kit consists of parts needed from dealership and it expensive. The mounting bushings which i make are the cheap part...lol

stockC43

That actually benefits me, I work at a dealer. . What parts do you need to make this swap work? I need to use the 3.07 ratio as that is what the c43 uses stock (or 3.06, can't remember) so I need a 209 diff but what else? Custom mounts, 209 diff flanges, pinion flange? What does the dss kit come with to adapt it?

cm60k

Yes sure, C43 uses "3.07" ratio,, with this swap,

Do you need to change the the diff. ratio....??

ZAYED,,

2PRECISE

The whole point of this conversion is to upgrade to the 215mm diff and put a bigger gear, at the same time bigger axles and driveshaft.

im running a 3.55.... waiting on a bigger gear...3.73 or 3.90 would be better.

cm60k

Do you mean smaller ratio "3.73 or 3.90", if so, i think they are soo small, the REV. will be soo high, means; high fuel consumption>> max limiter

around 230km,, more wheel spin(traction), im i right....??

ZAYED,,

stockC43

If you have a 99 car or earlier (gated shifter) it is much harder to do a gear ratio change. That is why "I" need to use a 3.07 gear. My c43 is a 98. Anything else would put it into limp mode. One way or another my car needs a LSD diff and through the r&d of blackbenz and others, have found the axles at the wheel hubs are weak. I was thinking of going to a ford 8.8 with dss axles but if this 215mm is a near bolt in with mostly oem parts and roughly equal cost I would rather have a oem look. However a ford 8.8 is available with a aluminum housing if your counting every lb, and every diff imaginable.

Change the diff. ratio, that’s the point, sorry to change a little bit of this topic, the big question,

how to reprogram our (TCU/EGS51)."P, R, N, D, 4, 3, 2, 1", to match any desired ratio...?, can we considering a PCS one of solution....??

That's a benefit but the point is to have a rear axle that can handle all the power you can throw at it. More clk's have busted axles than c43's due to more clk's being raced and are more common to have more hp from mods. Add slicks to that and stuff starts to break. C43's have a even smaller differential than clk55's so you need to worry about the diff braking that much more. I'm aiming to get as close to 500 rwhp as I can. A stock c43 is 225-250 rwhp or so.

As far as reprogramming the egs1, you can't as far as I know. I've "herd" you can use one from another car with the correct differential ratio but I've never tried it( ex e430 etc.) I've not herd of anyone successfully piggybacking the stock tcu yet either. I could be wrong though

Just saw your sig "c55" is your car a factory C55? If so you have the stronger clk55 diff. As well as a awesome super rare car

Good Input,,

I agree with you about the small diff., but for Example; even E/CLK430 got almost the same 4.3L & power as C43,, but they Equipped with a larger Diff. with 2.82, i think AMG believe that the small 3.07 is enough to handle the power with less weight, but im not sure about that,,

I think even if putting an TCU from another car it will not married with the ECU data file, it may work if replace the ECU with ME2.8, or reprogramming the Exist ECU & put a new data file in it, that can reads the TCU signal to reprogram it with a new diff. ratio.....

3.07, 2.82 etc. is not how strong the differential is. It is just how much torque multiplication it has. 3.07 accelerates quicker from a stop since the engine doesent need to work as hard. That's why the baby v8 4.3 has it and the more powerful 5.5 doesent. The 5.5 has more than enough torque (for "normal" people ) and can get by with the 2.82. 2.82= less highway rpm= better fuel econmy.

Read this thread, it better explains the different differential ring gear sizes. And you see what happens when it's too small.

Agreed,

I discussed with that thread & put some ques., with no luck...,,

i changed the ratio from 2.82 to 3.27, in my previous 500E, & used it about "3" years with-out any issues,

as well with my friends SL500, from 2.65 to 3.06, also with-out any problems,,

as you know; those models doesn’t need any kind of programming,, just rescale the km speed reading,

although 500E & SL500 got almost the same power as C43....

ZAYED,,

Thanks,,

My C55 is not original factory, i swapped the Engine from "W210 E55", i kept the factory C43 3.07 diff.,

My friend got an original C55, you are correct, his C55 Equipped with bigger diff. from "W210 E55/W208 CLK55",

which is 2.82, when i raced him, i took the advance from 0 to 170, then he cached me & go....

To my surprise/dismay, i took my tcu out of my 01 Clk55 with tip shifter and it has an egs51 in it! I'm not sure if s egs52 will just plug in and work but i can't find any for sake with correct ratio anyway. I've heard kleemann can tune for different gear ratio. Also i tested to see if dss axles will bolt to my stock diff and they did. I didn't go as far as to install with stock diff so length may be different. They sure are beefy and heavy.
The diff bushings are being a pain so I'm either going to have to find the special tool or cut then out. I tried making my own tool but couldn't find a washer big enough.

I can advise hoping from a 2.65 to a 3.27 is fun at the light but ruins highway driving unless you want to ruin your engine. The 3.27 would work good with a favorable 7 speed trans.
2presice - I saw a custom shim fab but what chassis carrier are you using 210 and what richmond gear type? Axle and side gear manufacturer? Outer hub respline or change.
I would love to see a link page for resources.
Give us some update PPPPleasEE

Cheers 48won, gator

2PRECISE

I have a 3.55 gear from richmond with a heavy duty quaife. i fit in a 215 diff cause it has more gear choices and larger spline count
