What does the STDX sizing mean for these bearings?

The STDX sizing indicates that these main bearings are 0.000040 inches undersize. This allows for fine-tuning of the oil clearance during an engine rebuild, ensuring optimal lubrication and performance.

What is the advantage of the XP Series tri-metal design?

King's XP Series bearings utilize a tri-metal construction with a high-performance overlay. This design offers increased strength and durability, along with better oil film retention and reduced friction compared to standard bearings.

Are these bearings suitable for performance applications?

Yes, the XP Series bearings are designed with improved strength and durability, featuring a thicker overlay and hardened steel backing to handle higher loads and reduce wear, making them suitable for performance-oriented engines.
