*Due to continued product improvement, the product illustrated on the photo may vary slightly from the actual product.
*Important note 1: before installation of RacingDiffs LSD conversion set, please inspect inner surface of small spider gears. It is important that it isn’t damaged from previous usage. Needs to be smooth, otherwise it will cause premature wear of new central pin and possible break down. If it isn’t completely smooth, please take gears to machine shop to process the surface.
*Also please note that all BMW models after year 2008 have welded ring gear to carrier unit. Installation of any kind of aftermarket LSD unit requires ring gear to be machined off which includes RacingDiffs Progressive LSD conversion set.
