What is the primary function of main bearings?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining proper oil clearance.

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

Tri-metal bearings use three distinct layers: a steel backing for strength, a porous bronze or aluminum alloy intermediate layer for bonding, and a lead-indium or lead-tin overlay for the bearing surface. This construction offers excellent fatigue strength and embeddability.

Are these bearings a direct replacement for the original equipment?

While designed for precise fit, it is always recommended to consult your vehicle's service manual or the manufacturer's fitment guide to ensure compatibility with your specific engine application.
