    FS: Large Case 210mm 3.91LSD 3.15LSD and 3.64 Differentials E31 E34 E32




    1) Large Case 3.91 LSD : Great upgrade for E34/E31/E32 8 and 12 cyl. cars, makes your car feel 500LB lighter, acceleration is greatly improved, biggest bang for the buck upgrade you can get...car comes alive!
    3.91 LSD was only offered in the US E-34 M5 up to 7/91,remaining years 92&93 used a 3.73 gear ratio.

    2) Large Case 3.15 LSD Upgrade for E31 850i 6 speed, E31 850ci 5 speed automatic, marginal upgrade for E31 840i 5 speed automatic and E34 540i manual.

    3) Large case 3.64 Open differential, great upgrade for 5 speed automatic E31 840i 840ci and some other BMWs.

    These differentials are a direct swap, all you need to do is swap the output flanges and the back cover, in some cases input flange.

    Prices and quantities available plus shipping:

    1) 3.91 LSD (1) $1700 ea
    2) 3.15 LSD rebuilt, 40% lock up. (1) $1600
    3) 3.15 LSD used, in great condition $1200.
    4) 3.64 open (3) $600 ea
    5) Custom fully professionally rebuilt large case 3.45 LSD and 3.64 LSD differentials upon request. (cost wise approx 1k cheaper than diffsonline or turner charges.)

    All differentials are in good shape without any noises or excessive shaft play.

    I believe the 318is has a small case diff, these are large case 210mm diffs.

    Does the ASC still function after installing an LSD to a 4-speed 850i?

    My apologies for the delayed response, been busy at work. I did receive your price, I will start new phase of upgrades the beginning of the year. If you still have any diffs at that point I will P.M you.

    Thanks!
