What does the 0.010in undersize mean for these bearings?

The 0.010 inch undersize specification means these bearings are designed to fit crankshaft journals that have been machined down by 0.010 inches. This is a common practice during engine rebuilding when the original journals have wear or damage.

What is PMaxBlack and Radialock technology?

PMaxBlack is King's technology designed to increase the load capacity of the bearing, making it more durable. Radialock is a feature that helps ensure the correct crush height, which is essential for the bearing to seat properly in the engine block.

What vehicles commonly use these bearings?

These bearings are suitable for many General Motors vehicles equipped with 262, 267, 302, 307, 327, and 350 cubic inch engines. Examples include models like the Chevrolet Camaro, Buick Regal, and Cadillac DeVille from various years.
