What does the +0.75mm size mean for these bearings?

The +0.75mm designation indicates that these bearings are undersized by 0.75mm. This means they are intended for use with a crankshaft that has been professionally machined down by 0.75mm to ensure proper clearance and fit.

What is the pmax Black material?

The pmax Black material is King Engine Bearings' racing line tri-metal bearing. It's engineered for improved fatigue strength and better performance under higher loads and oil pressures, making it suitable for performance and racing applications.

Do these bearings come with installation hardware?

This product is a set of main bearings only. Installation hardware, such as main cap bolts or seals, are typically sold separately and should be sourced according to your engine's specific requirements.

About this part

Product Details

When you're rebuilding the bottom end of a Nissan VG30DE or VG30DETT engine, especially for performance applications, the main bearings are critical. This set from King Engine Bearings is the XP series, which uses their pmax Black tri-metal material. This racing line is designed for engines that see higher loads and RPMs than stock.

These are a +0.75mm undersize bearing set, meaning they're meant to be used with a crankshaft that has been machined down by 0.75mm. The pmax Black material is known for its improved fatigue strength and ability to handle higher oil pressures, making it a solid choice for builds that push the limits. King is a well-known name in engine bearings, and this set is built to perform when you need it most.

This set fits a wide range of Nissan and Infiniti vehicles equipped with the VG30DE or VG30DETT engine, including models like the 300ZX, Maxima, and Infiniti J30. Always ensure your crankshaft has been properly machined to the correct undersize before installation.
