Looking to convert to 4.10 LSD

[b_something]

I am looking to convert to a 4.10 LSD rear differential. Which vehicles are proper donors of this unit? I have read that automatic cars are likely to have the 4.10. What about E36 cars? Will those rear ends bolt up? Forgive the lack of knowledge, I am a Honda/Acura convert.

Automatic e30 325is and some verts (I think) had 4.10 diffs. The e30 318is also had a 4.10 with LSD as an option, but they are small case diffs. They will fit, but aren't built for as much power. E36 diffs will not fit (except 318ti's, which are also small case.)

Just as a side note, I have a medium case 4.10LSD in my car right now that I will be pulling before too long. PM me if you're interested.

I am interested. Why are you pulling the 4.10?

Found an s50 and zf trans for cheap and the ratios are different. 4.10 is way too short for 1:1 fifth

The E30 M3 also has the 4.10 LSD.

The E30 M3 also has the 4.10 LSD.

Thanks for the info. I am in the market for one.
