What does '.026 undersize' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.026 inches. This is common when rebuilding an engine to correct wear or ensure a perfect roundness on the crank journals.

What is the pmax Black material?

The pmax Black is King Engine Bearings' tri-metal bearing material. It's known for offering improved strength and durability, making it suitable for performance builds or engines that experience higher loads.

Do I need to buy anything else to install these bearings?

When installing connecting rod bearings, it's essential to have engine assembly lubricant. You'll also need to ensure your crankshaft journals are clean and within the specified tolerance for these .026 undersize bearings. Always refer to your vehicle's service manual for detailed installation procedures.

About this part

Product Details

If you're rebuilding the bottom end of your 2002-2008 Mini Cooper with the W10B16A engine, getting the connecting rod bearings right is crucial. These are the King Engine Bearings XP Series, designed for performance applications. They are a .026 inch undersize set, meaning they're intended for crankshafts that have been machined down by that amount to true them up or account for wear.

The XP Series from King uses their pmax Black tri-metal material. This is a well-built bearing compound that offers improved strength and durability compared to standard bearings, making it a solid option for engines that see harder use or are being rebuilt to a higher standard. This set includes all four connecting rod bearings needed for your engine.
