What is the purpose of thrust washers?

Thrust washers are installed around the crankshaft to limit its forward and backward movement, known as end play. Proper end play is crucial for maintaining engine timing and preventing contact between the crankshaft and other engine components.

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

This particular thrust washer set is described as ideal for low to medium-load engines. For high-performance or racing applications, it's generally recommended to consult with a specialist or look for heavy-duty specific bearing sets.

Product Details

What you get in this kit are the thrust washers for your engine's crankshaft. These small but critical parts help control the crankshaft's end play, which is how much it can move forward and backward in the engine block. Keeping that movement in check is important for proper engine timing and to prevent damage to other components.

King Engine Bearings specializes in these kinds of parts, and this set uses a lead-free composite material over a bi-metal aluminum base. This construction is well-suited for engines that don't see extremely heavy loads, like many of the smaller displacement engines found in vehicles such as the Mazda Miata, Ford Escort, or Kia Rio. They are designed to manage the forces acting on the crankshaft while being environmentally safe.
