What does the +0.5 size mean for these bearings?

The +0.5 size indicates that these bearings are intended for use on a crankshaft that has been machined down by 0.5mm. This is a common practice during engine rebuilding to restore proper bearing clearances when the original crankshaft journals have been worn or ground undersize.

What is the pmax black coating?

The pmax black coating is a feature of King's racing line bearings. It's designed to reduce friction and improve oil flow characteristics, which helps protect the bearings under high-stress operating conditions.

Are these bearings suitable for a stock engine rebuild?

These are performance rod bearings with a specific racing line coating and are sized +0.5mm. While they can be used in a performance-oriented rebuild, they are not typically considered standard replacement bearings for a completely stock engine unless the crankshaft has been machined to the +0.5mm size.

About this part

Product Details

What you get in this box is a set of performance rod bearings from King Engine Bearings, specifically sized at +0.5mm. These are the pmax black racing line bearings, designed for engines like the Nissan VG30DETT 24-valve. They fit a wide range of Nissan, Infiniti, and Mercury vehicles, including popular models like the 1990-1992 Infiniti M30, 1984-1996 Nissan 300ZX, and 1993-2002 Nissan Quest.

These bearings are built with a tri-metal construction, featuring King's pmax black coating. This advanced coating is intended to reduce friction and improve oil flow, which is crucial for maintaining bearing health under demanding conditions. The +0.5mm sizing means these are meant for crankshafts that have been machined down by 0.5mm, often done during an engine rebuild to restore proper clearances.
