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

The +0.25mm sizing indicates that these bearings are slightly larger than standard size. They are designed to be used when the crankshaft journals have been machined down by 0.25mm to ensure a proper fit and oil clearance.

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

Tri-metal bearings offer a strong copper-lead alloy layer for load-carrying capacity, backed by a steel shell for rigidity. The enhanced babbit overlay provides a softer, conformable surface that helps with oil retention and reduces friction.

Are these bearings suitable for high-performance or racing engines?

These bearings are specifically noted as ideal for medium-load engines. For high-performance or racing applications that experience extreme loads and RPMs, it's recommended to consult King Engine Bearings' performance lines.

About this part

Product Details

If you're rebuilding the bottom end of your Mini Cooper with the W10B16A engine, getting the right connecting rod bearings is crucial. These bearings sit between the connecting rod and the crankshaft, allowing them to spin smoothly while handling the immense forces generated during combustion. King Engine Bearings has been focused on making top-notch bearings since 1960, and this set is built for engines that see moderate loads.

This set uses 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. This extra layer helps improve the bearing's ability to handle the pressures and friction it encounters, especially in engines that aren't constantly pushed to their absolute limits. Remember, these bearings are sized +0.25mm, so they're intended for use with a crankshaft that has been machined to match that size.
