BMW 188mm LSD Cap Upgrade by Diff Lab (E30 E34 E36)
Replace the broken cap on your 188mm LSD with this CrMoV alloy steel unit which comes with 8x uprated cap bolts. The 168mm and 188mm LSDs suffer failure of the cast cap which cracks around the bolts. This causes the bolts to fall out. The cap becomes loose, which ruins the bearing journal on the left side, which ruins the bearing journal on the left side cover. The parts needed to repair a diff with this problem can really add up. This is the strongest replacement cap available. It comes with a set of high tensile bolts which will not come out like the originals do, and don't suffer the head stripping problem of the original bolts. The new bolts can be torqued tighter than the originals onto the CrMoV cap. These are tried and tested, and built to last.
