View Full Version : Just install my new 4.10 Diff

Well, BMW Mississauga just installed my 4.10:1 differential. Going from a 3.73 to a 4.10 is a great upgrade and I suggest it to any E30 325 owner. Excellent value.

Since my older diff was wining a bit I decided to replace it. Now I notice significantly better acceleration, especially in 3rd, 4th and 5th.

The car is now even more of a joy to drive :)

Where did you get the diff from and how much? What about the labour cost?

a 4.10 diff is a standard 320i diff i thougt. But the 3.73 isnt that a big diff compared with the 4.10?

On my Hartge engine i have recently installed the big 3.73 because the small 4.10 is going into pieces when you drive long enough with it.

I got the diff from Phil. You'd have to search around classifieds to find one used.

The dealer book labour charge is supposed to be 3.5 hours.

is it limited slip, i am in the process of rebuilding my car. was going to rebuild the diff with 4.1 gears and found out it already has an m3 diff w/4.1 and a locker/spool. wtf, i wondered why it would chirp a little around turns and it the rain it really sucks to drive, but the driftting.....yeah! replacing it with 60% lock-up lsd.
