What does the +0.50mm size mean for these bearings?

The +0.50mm designation indicates that these bearings are designed for crankshaft main journals that have been machined down by 0.50mm. This is a common practice during engine rebuilding to clean up worn or damaged journals.

What is the tri-metal material used in these bearings?

The tri-metal construction combines three layers of different materials to offer a balance of strength, conformability, and embeddability. This helps protect the crankshaft journal and handle the stresses within the engine.

Are these bearings suitable for a stock rebuild?

These bearings are a solid option for a stock rebuild, especially if the crankshaft journals have been machined to the +0.50mm size. The advanced overlay and tri-metal construction offer improved durability over standard bearings.
