What does the .025 size mean for these main bearings?

The .025 size indicates that these bearings are undersized by 0.025 inches compared to a standard main bearing. This is necessary when the crankshaft journals have been machined down (reground) to this specific size during an engine rebuild.

What is the pMax Black material used in these bearings?

The pMax Black material is King Engine Bearings' tri-metal racing line. It's engineered for higher load capacity and improved durability, making it suitable for performance-oriented engine builds that may be subjected to more stress than a stock application.

Do these bearings come with a warranty?

King Engine Bearings generally offers a limited warranty on their products. For specific details regarding the warranty coverage and duration for this MB5286XP.026 set, please refer to the warranty information provided by King Engine Bearings.
