So I was looking at the Quaife website and noticed that they listed the lsd for the 500slc 107 chassis. I went on epc and found the carriers are the same for the slc and the big diff for the w124, eg 400e, 500e, e320, etc. I emailed Quaife and they sent me the diagrams for all their units and I measured a 500e diff. It seems as though it will fit. This would be for the 2.65- 3.06 gears. Same as the standard 500e carrier. I was going to find out how I can get this confirmed without dropping 1500 to not have it work but thought I would share.

My phantom grip unit actually locks up more than the quaife for a 1/3 of the price. Phantom grip is a kleeman style lsd block which is really all a mercedes needs. Much higher hp cars like 500hp open diff sr20 240's run phantomgrip blocks with no issues. The diff, as well as the rest of the car, is solid and wont be breaking anytime soon so I chose to improve upon the existing gears.

Also another member on this board or mbworld.org makes the kleemann style lsd block for I think $500.

I guess if the quaife gives you more peace of mind it would be good, but even the service cost of that diff would just be equal to replacing the phantom grip unit in the car.

so they made one for you?
i wonder if they can just send me the parts they used for yours and i can just fit them myself, as shipping my diff to america and back would be rediculusly expensive,

Oh yea our diffs are the same arent they? I'll give them a call and see if they will search their cad files.

yea thanks,
yes i beleive we have the same diff and suspension set up in our two cars

A Mercedes guy working on a 190E-16 created his own "phantom grip" block for less than half the price - eBay seller "evo2turbo". He doesn't have any available right now, they might be sold out. Check out this auction. I attached the photos below, for when the auction disappears from eBay's servers.

These will probably only fit on the 185mm diffs, not the 210mm. And, you have to eliminate the locking clips for the axle flanges... there will be nothing holding the axle flanges in place. When used on an open diff, there is really nothing except the face of the side gears providing friction to connect left & right... not really the best idea. The spring-block ("phantom grip") setup is better as an aid to a proper clutch-type LSD, where it's adding spring pressure to a clutch pack, similar to the factory ASD system.


Whipplem104, another option is the factory 210mm LSD, which will fit in your 210mm housing, for 2.65-3.06 gears. It's about $900 wholesale from the stealership, ready to bolt in. A bit cheaper than the Quaife, with none of the worries about if it will fit. I assume you've already seen my spreadsheet? I know a couple people who have already done this, and I'll be building a 2.65 LSD for my E500 this winter... already have the parts, just need to put it together.

Yes I know about both of these options. The factory lsd would be an option but I figure for the price being so close to the Quaife, why not use the Quaife unit if it fits. All the measurements say it should.

Check the part number on the R107 Quaife unit. If it is a different part number than any of their other Mercedes diffs, it just may work. If it's the same part number as their newer diffs (W210, C208, etc)... don't get your hopes up. Please let us know how it turns out, though. It would be nice to get final confirmation on the Quaife unit - if it works, they could update their website to include the 210mm W124 and R129 applications.

The 107 diff is the one I am looking at. Quaife sent me all the dimensions on their units. I measured the diff on a 500e. My measuring equipment is not quite right for this but it seem s to be identical. Also I checked the epc. The updated carrier for the 107 is the same as the 500e carrier and many others.
What I have gathered is that mercedes made different carriers for different gear ratios in the same housing instead of shiming the ring gear. This is why the gear ratios are limited. Most of the units listed by Quaife are very close to each other other than bearing size and were the ring gear is located from side to side.
I was thinking of sending a carrier to Quaife to confirm the fit. I may just take one to a machine shop and have it measured accurately.

Could you share the part number of the Quaife differential for the R107? I don't see it in their application list. And I can't find any reference to a Quaife R107 diff on Google, either...

It is the qf5v or something. It says 500slc, which is the 450slc 5.0.
There is a 4th diff that they sent me and they do not know what it goes to.
Other than the 500slc one, all of them have the casting number off the carrier that is not the actual part number, such as 220 353 -----. I also have found this type of number on both the 129 differential carriers.
I am astounded that Quaife makes products that it has no idea what the application is. Their response has been that someone sends them a carrier and they make a unit. They do not know what it goes to.

Yeah, I saw that 500SLC on their UK website, but not the US site. They had horribly little information. I thought the R107 had taller gears, like the 2.47's used in all the 116 and 126 applications?

You're right, though, MB used different carriers for different gearsets, rather than shimming the gears. I think clearances are so tight in there, that a universal setup may not have worked. (?) The 2.47 LSD units are fairly common in junkyards now, but not many people are interested in tall gears like that. I know I'm not!

It should be interesting, though... I'd ship the W124 210mm open diff to Quaife and let them figure out if they have something which is a bolt-in. The lifetime warranty is nice, and the price really isn't that bad ($1500?), compared with the fancy $3-$4k Japanese units I've seen. On a budget, the factory clutch LSD ain't bad, and on really tight budget the Phantom-Grip would at least be worth a try if you could get it for more like $200 instead of $500.
