What is the main purpose of thrust washers?

Thrust washers are crucial components in an engine that control the end play of the crankshaft. They prevent the crankshaft from moving too far forward or backward within the engine block, which is essential for proper engine operation and longevity.

What does 'bi-metal aluminum material' mean for these bearings?

A bi-metal construction typically involves a steel backing for strength and an aluminum alloy overlay for bearing surface properties. This combination offers a good balance of durability and performance for the specific load conditions these washers are designed for.

Are these washers suitable for high-performance or racing engines?

These specific thrust washers are noted as ideal for low to medium-load engines. For high-performance or racing applications, it's always best to consult the manufacturer's specific recommendations for your engine build.
