I just put a billet wheel on my HE351VE and the motor really loved it but the diff not so much. I am trying to figure out what diff to go with. I would love more gear but want to know how much it will affect mileage. If it did affect mileage I may even go lower numerically. I have a 722.6 though and I know with my current gearing I can go over 100 mph and I am still below 3k. How hard is it really to find Lsd diff?

Hey what size wheel did you go with?
My car isn't fully running with my turbo yet.

I had an hx40 with an aftermarket billet wheel that I just took it out of. I think it was like maybe 150 when I bought it.

I would recommend getting a 2.65-2.82 ratio diff. As far as lsd goes the factory ones are all worn out. And if you get in the 2.65-3.06 ratio you can just get a quaife lsd. And install it in the case. I do not know which diff housing your car has but you may have to swap half axles if you change to the larger diff housing.

As far as I know mine came with a 2.87 or something 2.8. Who sells these diffs that you speak of? I have heard of them but never seen anyone selling them.

The yard sent me a picture of the inside of this carrier and it looks to me like maybe there is clutch disks inside but I am unsure.  I attached the pic at bottom but will figure a way to post it later.

Quaife is out of the UK. They have dealers all over the world. If you have the right housing. The 210mm diff is a qdf5v. I used to have an accnt with the U.S. wholesale dist but I have not done business with them in a long time and they closed it. They retail at around 1500.00 plus install.
The best thing is they do not wear out. The oem one has about 5-10k of street driving and it s toast and then you have an open diff and it needs to be rebuilt. Or about 30-40 min of good hard use.

This is a 126 right? Did they put 185 R&P's in those? I thought they all had big diffs.

The quaife will be a significant upgrade over a perfectly functioning Merc LSD. I wouldn't bother on a w126 though. <hater>

Yeah it is on a 126. On my CL65 I have a $1900 quaife but yeah I dont think I would spend anything like that on it either. What is this 185 R&P?

Well I ordered that 2.46 LSD diff and will give it a shot. I only paid $150 for it. So it a 17% lower ratio. My car with the 5 speed auto is already at 80 at 2k now it will be even lower. The 300SE's have a 3.46 ratio and I may try that at some point. That's 20% shorter. I can get those diffs for $90

Update....the diff I got was not a 126 diff so I went and got a 3.46 ratio diff out of a 300SE and what a good decision! I am loving it and cant believe how much of a change it is.
