What is the purpose of the pMaxBlack coating on these bearings?

The pMaxBlack coating is designed to assist with the initial oil film formation when the engine starts. It can also offer improved durability for the bearing surface under operating loads.

Why is the housing bore 0.003 inches larger than standard?

This larger housing bore size is often necessary when rebuilding an engine, especially if the crankshaft has been machined or if you need to achieve specific oil clearances. It ensures a precise fit for the bearing within the connecting rod.

Are these bearings sold individually or as a set?

These are sold as a set, meaning you receive all the necessary connecting rod bearings for your Subaru FB20 engine in one package.

About this part

Product Details

When you're rebuilding the bottom end of your Subaru FB20 engine, getting the connecting rod bearings right is crucial for long-term health. These bearings from King Engine Bearings are specifically made to handle the demands of a rebuilt or performance engine, ensuring proper oil clearance and smooth operation.

The pMaxBlack coating on these bearings is a notable feature. It's designed to help with initial oil film formation during startup and can offer improved durability under load. They are also built with a housing bore that's 0.003 inches larger than standard, which is important for ensuring the correct clearance when you're working with machined or modified crankshafts. This attention to detail in manufacturing helps ensure a solid fit and reliable performance.

For a successful engine build, always refer to your Subaru service manual for the correct torque specifications and installation procedures for your connecting rod bearings.
