E21 Limited Slip Differentials

Aardvarc occasionally stocks the following:

  • Factory E21 LSDs, either in good used condition or fully rebuilt.
  • Custom E21 LSDs, either in good used condition or fully rebuilt. These units are created by converting an open E21 differential to a limited slip using the clutch assembly spool from a 1993-1995 E36 318i. This spool is highly regarded as being superior to the E21 spool. The post-assembly measured break-away or preload torque near 31 ft-lbs, which is about 10% greater preload than a standard E21 LSD.
