What is the primary function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while minimizing friction and maintaining proper alignment, which is essential for engine operation.

What does 'tri-metal construction' mean for these bearings?

Tri-metal construction refers to a bearing design that uses three distinct layers: a steel backing for strength, a lead-indium overlay for conformity to the crankshaft, and a copper-lead or aluminum-tin alloy layer for durability and reduced friction.

Do these bearings come with new crankshaft bolts?

This listing is for the main bearing set only. Crankshaft bolts are typically sold separately, and it's recommended to use new, high-strength bolts when rebuilding an engine.
