What does the 0.011 undersize mean for these bearings?

The 0.011 undersize designation means these bearings are intended for use when the crankshaft journals have been machined down by 0.011 inches. This is a common practice during engine rebuilding to ensure a fresh, perfectly sized surface for the new bearings.

What is the PMaxBlack material?

PMaxBlack is a proprietary material developed by King Engine Bearings. It's known for its ability to handle higher loads compared to standard bearing materials, making it suitable for performance and heavy-duty applications.

What is the benefit of the Radialock feature?

The Radialock feature is designed to help maintain the correct crush height of the bearing. Proper crush height is crucial for ensuring the bearing stays securely in place within the engine block and maintains adequate oil film thickness.

About this part

Product Details

The PMaxBlack material used in these King Engine Bearings main bearings offers superior load capacity, a critical factor when you're rebuilding or refreshing a performance LS engine. These bearings are specifically sized at 0.011 inches undersize, intended for applications where the crankshaft journals have been machined to match. King has been a specialist in engine bearings since 1960, focusing on supplying well-built components.

These main bearings utilize a tri-metal copper-based material, which is a popular choice for performance applications due to its excellent embeddability and strength. The Radialock feature helps ensure optimal crush height, which is essential for proper bearing seating and oil retention within the engine block. This combination of materials and design helps these bearings handle the demands of engines like the Chevy LS1, LS6, and LS3.

This set is designed to fit a wide range of GM Vortec and LS-series Gen III and IV engines, including popular models like the Chevrolet Camaro, Corvette, and Silverado 1500. When rebuilding your engine, using bearings with the right material properties and precise sizing is key to ensuring longevity and performance.
