This ACL High Performance rod bearing set is sized for a standard, unmachined connecting rod journal on the Nissan VG30DETT (3.0L-V6) engine, built with extra oil clearance for engines running higher oil volume/pressure or looser bearing clearances (common in turbocharged or high-RPM builds). Per ACL's own fitment data this bearing size is shared across VG30-family applications including the Nissan 300ZX (Turbo and 2+2), Maxima, Pathfinder, Quest, Frontier, Xterra, D21/Pickup, and the Infiniti J30, M30, and QX4. Rod bearings support the connecting rod on the crankshaft journal and are matched with main 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 vehicles does this rod bearing set fit?
Per ACL's fitment data, it's sized for the Nissan VG30-family V6, used in the Nissan 300ZX (Turbo, 2+2), Maxima, Pathfinder, Quest, Frontier, Xterra, D21/Pickup, and the Infiniti J30, M30, and QX4.
Do I need main bearings too?
Yes, this listing is for rod bearings only. Main bearings for the VG30 V6 are sold separately.
Is this a Standard size or an oversize bearing?
This is Standard size — sized for a stock, non-machined rod journal — with extra oil clearance built in.
