I recommend that a rear end specialist do the conversion, but it is not too difficult and a competent shade tree mechanic can complete the conversion. Just take out the open spool, remove the ring gear, install the ring gear on this LS spool, reassemble, and you have yourself a limited slip. No special setup required, but make sure everything is clean before installing the rear cover. Fits 3.15 and shorter gears from the'80s and'90s, including E36 325i/S 3.15:1 ratio open diffs.
May not fit 3.07 and taller gears from "eta"type differentials. BMW stopped installing LSDs in non-M cars in the late'90s, so here is your chance to obtain what seems to be a very rare item.Thanks for checking this out. Powered by SixBit's eCommerce Solution.
