We now carry aftermarket replacement carrier caps for 188mm BMW differentials!
It's common to see broken bolt tabs on the 188mm differential carrier caps. This is due primarily to the weak carrier cap bolts utilized from the factory - when the bolts fail, the excessive pressure creates a chain reaction causing fractures on the tabs.
These caps are a direct replacement with increased strength by utilizing chromium molybdenum vanadium (CrMoV) steel. Included, at no charge, are a set of upgraded cap bolts.
Select high offset for gear ratios 3.15 and greater. Select low offset for gear ratios 3.07 or lower.
