What is the pMAX black coating?

The pMAX black coating is a specialized racing layer applied by King Engine Bearings. It's designed to reduce friction and improve wear resistance, making it suitable for high-performance and racing engine applications.

Why are these bearings 0.5mm undersize?

The 0.5mm undersize indicates these bearings are intended for use when the engine's crankshaft journals have been machined down by 0.020 inches (0.5mm). This is a common practice during engine rebuilding to ensure a proper fit on a worn or resurfaced crankshaft.

What else might I need for installation?

Proper installation requires careful cleaning of the crankshaft and block, assembly lube, and a torque wrench to tighten the main bearing caps to the manufacturer's specifications. Always consult the service manual for your specific RB25DET engine.

About this part

Product Details

If you're rebuilding the bottom end of your Nissan RB25DET engine, especially for performance applications, the main bearings are a critical component. These King Engine Bearings are specifically designed for the RB25DET 24V engine and come in a 0.5mm undersize, which is important if your crankshaft journals have been machined.

King uses their pMAX black coating on these performance bearings, which is a specialized racing layer that helps reduce friction and wear, especially under high-load conditions. This coating is well-known in racing circles for its durability and ability to handle the stresses of a performance engine. The set includes the main bearings needed to replace the factory ones, ensuring a solid foundation for your engine build.

When installing these bearings, it's crucial to ensure your crankshaft journals are clean and within the specified tolerance for the 0.5mm undersize. Always refer to the manufacturer's installation instructions for proper torque specifications and any specific assembly procedures.
