What does the 0.25 size mean for these bearings?

The 0.25 size indicates that these bearings are 0.25mm undersize. This means they are intended for use with a crankshaft that has been machined down by 0.25mm, typically to correct for wear or to achieve specific bearing clearances during an engine rebuild.

What is the pmaxkote coating and why is it important for racing?

Pmaxkote is a polymer coating developed by King Engine Bearings for their racing line. It helps to reduce friction and improve oil film retention, which is crucial for protecting bearings under the high loads and temperatures experienced in racing applications.

Are these bearings a direct replacement for stock RB26DETT main bearings?

These are a performance upgrade and are sized 0.25mm undersize. They are not a direct replacement for stock bearings unless your crankshaft has been machined to match this undersize. Always consult your engine build specifications or a qualified mechanic to ensure correct fitment.

About this part

Product Details

This is a set of performance main bearings from King Engine Bearings, specifically designed for the Nissan RB26DETT 24-valve engine. You get the complete set of main bearings needed for a rebuild or overhaul of your RB26DETT's bottom end. These bearings are built with King's pmaxkote racing line, which is a polymer coating that helps reduce friction and wear, especially under high-performance conditions.

The RB26DETT is a legendary engine, and keeping its critical rotating assembly healthy is key to its longevity and performance. These bearings are sized at 0.25mm undersize, meaning they are intended for crankshafts that have been machined down by 0.25mm to correct for wear or to achieve specific clearances. The pmaxkote coating is a notable feature for anyone pushing their RB26DETT hard, as it offers an extra layer of protection and improved oil film retention during demanding use.

When rebuilding a performance engine like the RB26DETT, attention to detail in bearing selection makes a difference. These King bearings are a solid option for those looking for a well-built component with a performance-oriented coating.
