What is the purpose of main bearings in an engine?

Main bearings sit between the crankshaft and the engine block, supporting the crankshaft as it rotates. They help maintain precise clearances and reduce friction, which is vital for engine health and performance.

What does the 'tri-metal overlay' mean for these bearings?

A tri-metal overlay is a common material used in performance and heavy-duty bearings. It provides a strong yet conformable surface that helps maintain oil film and resist wear under demanding engine conditions.

Do I need to measure my crankshaft journals before installing these bearings?

Yes, it's highly recommended. You should always check your crankshaft journals for wear, straightness, and proper diameter before installing new bearings to ensure they meet the manufacturer's specifications.
