F/S 2.47 W126 Rear
 

I have a 2.47 rear end from a 420SEL that I was going to put on my 300SD. I never got around to it and now that I am driving the 300SDL I do not need it.

I paid $120 for it.

Anybody interested?

It is in a crate, but is heavy and will cost probably $50-$70 to ship.

Is it a LSD?

Do these actually fit right into a 300SD? Or is anything else needed, like spacers? I read that the input shaft needs to be swapped, thats not big deal, but is anything else involved?

What year was the 420? Later model diff's have a different style mounting setup....and won't work with a 300SD....

Some pictures would be good....I might be interested. I will be doing a considerable amount of freeway driving this summer and lower rev's would be so nice....

2.47 into a 3.07?
 

Yes! I too would like to know more about this swap...does the 2.47 fit into the same spot as the 3.07? or are there "tricks" required? I sure like the idea of cruiseability improvement (noise/mpg too!) If someone can clear it up for me that would be great! thanks for the sharing as I am new to these fine rigs! ya vol!

2.47 into a 300sd?
 

I just found a 2.47 rear diff in a 87 or 88 380se and was wondering if these would fit in an 83 sd? thanks for any info! ya vol!

The diff will not fit the '83.

2.47 rear diff won't fit 83' 300sd
 

thanks for info....how about older v8 w126 cars? (like 420sel,450sel etc?) thanks again! Mike

I don't believe the 420 or the 450 was offered in the years between '81 and '85. You'd be looking for a 380 or a 500. Either of those gassers would have the diff.

380SE was not made past '85 in US, it was 84-85 only. Being that, you probably found a 300SE which was available starting in 1988.

Couldn't have been the 300SE because it had a much shorter diff...........something like 3.46 or so........to keep the revs up on the small engine.

Hrm, good point. No telling what was found then.
