What is the PMaxBlack technology?

PMaxBlack is a proprietary technology from King Engine Bearings designed to increase the load capacity of the bearings. This helps them withstand higher stresses, which is beneficial for performance engines.

What does 'STD' size mean for these bearings?

STD stands for Standard size. This means the bearings are meant to be installed on a crankshaft that has not been machined undersize or oversize. They are the factory-sized bearings.

What is the benefit of a tri-metal copper-based material?

Tri-metal bearings, often copper-based, offer a good balance of strength, conformability, and heat dissipation. This makes them a popular choice for performance engine builds where higher temperatures and loads are expected.

About this part

Product Details

If you're rebuilding the bottom end of a GM LS-series engine, like those found in many Chevrolet Camaros, Corvettes, or Silverado trucks, a solid set of main bearings is crucial. This main bearing set from King Engine Bearings is built with a tri-metal copper-based material, which is a common and well-regarded choice for performance applications due to its strength and thermal properties.

King has been specializing in bearings since 1960, and this set includes their PMaxBlack technology, designed to handle higher loads. It also features Radialock, which helps maintain optimal crush height during installation, ensuring the bearing seats properly. These bearings are a standard size (STD), meaning they are intended for crankshafts that are still within their original factory specifications.

This set is designed to fit a wide range of GM vehicles equipped with LS-based engines, from performance cars like the Corvette and Camaro to trucks and SUVs like the Silverado and Escalade. Always refer to the full fitment list to confirm compatibility with your specific application.
