What does the 'SI010' in the part number mean?

The 'SI' typically refers to King's high-performance overlay material, known for its durability. The '010' indicates that these bearings are 0.010 inches undersize, meant for crankshafts that have been ground down to this specific dimension during an engine rebuild.

Are these bearings suitable for a stock rebuild?

Yes, these bearings are designed for Chrysler 426 and 440 V8 engines. The 0.010 undersize is specifically for engines where the crankshaft journals have been machined to match this size during a rebuild process.

What is the primary function of main bearings?

Main bearings sit between the crankshaft and the engine block, supporting the crankshaft's rotation. They are crucial for maintaining proper crankshaft alignment and handling the immense forces generated during combustion.
