Which Quaife Differential Part Number?

[Cass23VSU4]

Which Quaife differential is the correct one for 5.7L 210mm housing?

During my product searches I've found three:

- P5153693 $2600 = The double priced MOPAR part.
- #48.309.190 $1795 = Shares part number with the AMG W210 E55.
- #QDF7V $1395 = Lesser of the three evils price wise.

I had plans on making this purchase this week or early next week, but the multiple part numbers have thrown me off. Also of all the part numbers listed above, it seems the MOPAR part number is the only one that seems to come with an install kit.

So with all that being said, those who have purchased, installed or abosolutely know, what part number is the right one? And which one is the best bang for the buck?

Thanks in advance.

I would call HHP.....they have them on sale for less than $1k for the 210mm rear.

^^Definitely talk to HHP, especially if you're also thinking about changed gears. HHP uses Ultrax in Calif. as a custom diff installer. My Quaife was done by Ultrax and it's been flawless.

Thanks for the HHP tip, I'll contact them and see what they have to say.

Autotech has their inventory sale going on as well and the #48.309.190 they list for the 5.7L is $797.15, so I don't want to pass it up.

Is that the right part number for the 210mm diff and a real price?? Are the prices for aftermarket performance parts finally coming way down??

UPDATE:

The three part numbers listed above are in reference to the same Quaife ATB Differential for the 300C/Mangum/Charger 5.7L 210mm. The difference in part number is in relation to the different US distributor's product cataloging system.

The only difference is in the MOPAR #P5153693, which supposedly is a full kit and comes with carrier bearings, axle seals, preload shims, ring gear bolts and complete instructions. Fotunately, this question was answered by a local Mercedes repair shop.
