    This ACL High Performance main bearing set is sized for a standard, unmachined crankshaft main journal on the Honda D16A6, H22A4 (97-01), and F23A (98+) engine family, built with extra oil clearance for engines running higher oil volume/pressure or looser bearing clearances (common in turbocharged or high-RPM builds). Main bearings support the crankshaft in the engine block and are matched with rod bearings to control bottom-end clearances.

    FAQ

    What does "Extra Oil Clearance" mean?

    Extra oil clearance bearings run a slightly looser clearance than standard, which some high-RPM, high-oil-volume, or turbocharged/nitrous applications prefer for additional oil flow and thermal margin. Use standard clearance unless your engine builder specifies extra clearance.

    What engines does this main bearing set fit?

    It's sized for the Honda D16A6, H22A4 (97-01), and F23A (98+) engine family.

    Do I need rod bearings too?

    Yes, this listing is for main bearings only. Rod bearings for this engine family are sold separately.

    Is this a Standard size or an oversize bearing?

    This is Standard size — sized for a stock, non-machined main journal — with extra oil clearance built in.
