What does '0.020 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.020 inches smaller in diameter than a standard size bearing. This is necessary when the crankshaft journals have been ground down (undersized) during an engine rebuild or repair process.

What is the XP Series from King Engine Bearings?

The XP Series represents King's high-performance line, utilizing a specialized tri-metal material with an advanced overlay. This design is intended to offer greater strength, improved wear resistance, and better performance under higher loads and temperatures compared to standard bearings.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit, it is always recommended to consult your vehicle's specific service manual for detailed installation procedures and torque specifications to ensure proper engine assembly.
