Product Details


This factory finned differential cover bolts directly to the E30 diff housing. This is a must for track cars with limited slip differentials. The clutch packs in these diffs generate a lot of heat, the more heat you can dissipate the better. The fins on this cover will do just that. This is an inexpensive upgrade that may save you a lot of money down the road. Plus it looks cool.

Kit includes cover, gasket and all necessary hardware.:

  • 1 x 33112228335 - Differential Cover
  • 1 x 33111210405 - Differential Gasket
  • 2 x 07119914114 - Bolt
  • 4 x 07119921522 - Bolt
  • 2 x 07119921541 - Bolt
