FAQ
What does "0.025mm Oversized" mean?
It means the bearing is machined 0.025mm over standard thickness, for use with a connecting rod journal that has been reground 0.025mm undersize.
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.
How do I know if I need the 0.025mm oversize instead of Standard?
Your engine builder or machine shop will specify the size based on how much material was removed when the crankshaft was reground. Standard size is for a stock, unmachined crank.
