What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the connecting rod journals on your crankshaft have been machined down by 0.25mm. This is a common practice during engine rebuilding to clean up minor wear or imperfections on the journal surface.

What is the advantage of the Tri-M+ babbit overlay?

The Tri-M+ enhanced babbit overlay is a unique feature from King Engine Bearings. It's designed to improve oil retention within the bearing surface and enhance its resistance to wear, contributing to a longer lifespan for the bearing.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are ideal for medium to high-load engines, which includes many stock applications that might see regular use. Their construction with a tri-metal copper-based material and enhanced babbit overlay offers a well-built component for a reliable engine rebuild.

About this part

Product Details

When you're rebuilding the bottom end of your Honda or Acura engine, especially one that sees medium to high loads, getting the connecting rod bearings right is crucial. This set from King Engine Bearings is built with a tri-metal copper-based material, which is a solid foundation for durability. On top of that, it features King's Tri-M+ enhanced babbit overlay, a unique design that helps improve oil retention and wear resistance, giving you more confidence in the longevity of your rebuild.

These bearings are sized at +0.25mm, meaning they're intended for use when the connecting rod journals have been machined down by that amount to clean up wear or damage. King specializes in bearings, and this focus shows in the well-built nature of their products, aiming to provide a reliable component for your engine's critical rotating assembly.
