Ok thanks for the help. Ill get in contact with my tunee then!

 

I thought the diffs came blank and you had to transfer your own ring gear, keeping the ratio the same. Am I missing something here?

 

No, you are correct. Poster above is just confirming mis-information.
I guess it is possible and convenient to change ring gear ratios if/when you install an LSD, but gear ratios are completely unrelated to the LSD internals itself.

Let's make it clear for everybody going forward:

• LSD aftermarket (and factory options) consist of spider-gear replacing devices
• The input side of an LSD is a ring-gear mounting surface where the factory ratio ring-gear is mounted
• The output side of an LSD are two female spline drive cavities where factory axles slide into
• The device itself generally represents a conical shape tapering away from the ring gear

 

Yeah after reading some diys i came to the same conclusion. It was quitw apparent when i saw them swappin the gear ring over and the part # and ratio was engraved on the gear hehe

 

Thanks for helping me so far,with a lsd install looming next week ive got another question!

Ive been reading through old threads, people speculate that upping the ratio to 282/306 is counter productive in modified, higher hp m113ks. From what i understand changing ratios is considered the 'poor mans supercharger' and as such itll just introduce traction problems and i assune lower final drive for higher gears/speed? With 500 odd whp on dynojet would this be a recommended upgrade?

 

I had the option to do it - I didn't.

YMMV

 

 

Lol its 60mph here but i got a radar..

i think ill just ask the diff shop who im planning to install if they can easily/cheaply source the gear. If its a hassle ill just stick with stock.

 

 

Where'd you source those, what was the price per unit?

 

Clutch type eh,what do those go for?

 

Drexler is the OE/M manufacturer for P03X AMG cars.

 

If I get more of those again I’ll let you know. Yep they are OEM P30 Performance Package LSD.

 

do we have a price on these?

 

 

Dear all,

this may sound like a stupid question, and I hope to know the answer, but would like to make really sure! I am new to the W211 platform, so please excuse if this has already been discussed.
Yes, I did search other threads!

How do I make sure whether my E55 has a HAG 215?

MY car is early 2004, still has 280 blower, was delivered in Dec 2013, but when I lie under the car and check the drive shafts, I cannot see any bolts. So as this is an early 2004 MY, it should have the old style bolted axle shafts, right? But I see no bolts. Is is safe to assume I have the HAG215 and new style splined axles?
Is there no difference to the diff housing / casting?
I ask this, because I already have a Wavetrac LSD and would like to understand what other parts I need for the installation of the LSD.
Is there a good reference thread about this somewhere?
Best regards,

Tadek

 

Didn’t you ask this recently in Facebook?

 

I am normally not active on facebook. So, no. But if there is an answer to this question there, I‘d appreciate if you pointed me to it.

 

Someone with the exact same car, same reason and same story just asked that question a few days ago. I don’t look it up as you can’t find anything on this stupid platform but I can help you with your project. Send me a PM later or tomorrow to remind me.

 

So to put an LSD in the E55 you also to recode the ECU?

 

No, unless you are also changing gear ratio.

 

Yes, your car has a HAG 215

 

Awesome! That is what I thought. Just got concerned when someone said early 2004 cars had HAG210.

Thanks!

Is there a good / preferred source for new bearings etc. as an alternative to Daimler / MB?

 

Thanks Joe.

 

LSDs have usually 2.82 or even 3.06 gear ratio.

I can help him with that too if he wants.
