What is the primary function of crankshaft main bearings?

Crankshaft main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on, ensuring proper oil clearance and reducing wear.

What does 'lead-free composite' mean for these bearings?

The lead-free composite material is an environmentally safer alternative to traditional bearing materials that contained lead. It's designed to perform well in low to medium-load engine conditions.

Does this bearing set come with everything needed for installation?

This set includes the crankshaft main bearings. It's recommended to refer to your vehicle's service manual for any additional components or specialized tools that may be required for installation.
