What does the 0.025mm size mean for these rod bearings?

The 0.025mm designation means these bearings are undersized by that amount. This is typically used when a crankshaft has been machined (ground) undersize to clean up wear or to achieve a specific clearance. You'll need to ensure your crankshaft journals are prepared to this exact size for proper fit and oil clearance.

What is PMaxBlack technology?

PMaxBlack is a technology developed by King Engine Bearings that enhances the load-carrying capacity of their bearings. It's designed to help the bearings withstand higher stresses, which is beneficial for performance or heavily used engines.

What is the benefit of a tri-metal copper-based material?

Tri-metal bearings, like these copper-based ones from King, offer a good balance of strength, conformability, and embeddability. The copper-lead-tin composition is known for its durability and ability to handle the high pressures found in performance engine applications.

About this part

Product Details

If you're rebuilding the bottom end of your Nissan RB25DET or RB26DETT engine, getting the right rod bearings is crucial for long-term health and performance. King Engine Bearings has been focused on making top-notch bearings since 1960, and this set is built with their specialized knowledge.

These bearings use a tri-metal copper-based material, which is known for its strength and ability to handle significant loads. They also feature King's PMaxBlack technology, designed to give you superior load capacity, meaning they can take more stress without failing. The Radialock design helps ensure optimal crush height, which is important for proper seating and performance within the connecting rod and crankshaft assembly.

This set is specifically sized at 0.025mm undersize, so make sure your crankshaft journals are prepped to this specification for a direct fit. King's focus on specialization means you're getting a well-built component designed for the demands of performance engines.
