What does the 0.020 size designation mean for these bearings?

The '020' in the part number indicates that these bearings are 0.020 inches undersize. This means they are intended for use when the engine's crankshaft journals have been machined down by 0.020 inches during a rebuild to correct wear or damage.

Are these bearings suitable for a stock rebuild or a performance build?

These bearings feature a bi-metal aluminum construction with a lead-free composite, making them well-suited for high-performance applications. They are designed to handle increased stress and heat often found in modified engines.

What is the benefit of a lead-free composite bearing?

The lead-free composite offers an environmentally safer alternative to traditional bearings that contain lead. This construction is also engineered for high performance, ensuring durability and reliability in demanding engine conditions.
