What is the main purpose of connecting rod bearings?

Connecting rod bearings are precision components that sit between the connecting rod and the crankshaft. Their primary job is to maintain a very thin, controlled layer of oil, allowing the rod to rotate smoothly around the crank journal without direct metal-to-metal contact.

Are these bearings for a specific engine configuration?

Yes, this set is specifically designed for Buick V6 engines with displacements of 181ci, 204ci (1989-1990), 231ci Type A (even fire), 231 Turbo, and 252ci. It's important to confirm your engine's configuration matches these specifications.

What is the significance of the '.660" wide bearing' specification?

The '.660" wide' refers to the width of the bearing surface. This specific width is critical for proper fitment and oil distribution on the crankshaft journal for the engines this bearing set is intended for.
