Don't confuse extra clearance with oversize. In this context oversize means the shells are thicker to compensate for repaired crankshafts that have had their journals ground down.

I've installed 7 or 8 sets of ACL bearings in engines so far because of BE's inconsistent supply. No issues.
Deansbimmer, did you use the HX as well or only STD so far? BE's measurement suggesting already ACL's STD shell has increased clearance makes made me think twice about the HX.

Thanks
