What does '0.040 inch undersize' mean for these bearings?

This means the bearings are manufactured to be slightly smaller than standard size. They are intended for use with a crankshaft that has been machined down by 0.040 inches to account for wear or damage.

Do these bearings come with new hardware?

This set includes the connecting rod bearings only. New connecting rod bolts are typically recommended and sold separately.

What is the typical lifespan of connecting rod bearings?

Lifespan varies greatly depending on driving habits, oil maintenance, and engine condition. Regular oil changes and avoiding hard acceleration on a cold engine can help extend their life.
