What does the +0.25mm size mean for my engine?

The +0.25mm sizing indicates that these bearings are 0.010 inches larger in diameter than standard size. This is typically used when the crankshaft journals have been machined down (ground) to a larger size to compensate for wear or to achieve a specific clearance with performance modifications.

What is PMaxBlack material?

PMaxBlack is a proprietary material developed by King Engine Bearings. It is designed to offer enhanced load-carrying capabilities, making it suitable for high-performance engines that generate more stress on the bearings.

Are these bearings suitable for a stock RB26DETT engine?

While designed for performance, the PMaxBlack material and construction can benefit even a stock RB26DETT. However, the +0.25mm sizing is critical; these bearings should only be used if your crankshaft journals have been machined to match this size.

About this part

Product Details

King Engine Bearings is a specialist in engine bearings, and this performance main bearing set is made for the Nissan RB26DETT engine. These bearings are sized at +0.25mm, meaning they are 0.010 inches larger than standard size, which is important if you're rebuilding or modifying your engine and need to account for crankshaft journal wear or modifications. This set is designed to handle the demands of a performance RB26DETT build.

The key technology here is King's PMaxBlack material, which offers superior load capacity. This is crucial for high-performance engines that experience increased stress. They also use Radialock, a feature that helps achieve optimal crush height, ensuring the bearings seat properly in the block for consistent oil clearance. The tri-metal copper-based material provides a solid foundation for durability and performance under demanding conditions.
