What does the '+.020mm' sizing mean for these bearings?

The '+.020mm' indicates that these bearings are slightly larger than standard size. They are intended for use when the crankshaft journals have been machined down by 0.020 millimeters to ensure a proper fit and oil clearance.

What is PMaxBlack and Radialock technology?

PMaxBlack is King's tri-metal copper-based material that offers superior load capacity, making the bearings more durable under stress. Radialock is a design feature that helps maintain the correct crush height, ensuring the bearing seats properly in the engine block and cap.

Are these bearings a direct replacement for all LS engines?

These bearings are specifically for GM Vortec/LS-Series Gen III/IV engines and are sized +.020mm. While they fit many popular LS vehicles, always verify your engine generation and crankshaft journal size before purchasing to ensure compatibility with your specific build.

Product Details

This is a set of 10 crankshaft main bearings from King Engine Bearings, specifically sized at +.020mm. These bearings are designed for GM Vortec and LS-Series Gen III/IV engines, which are found in a wide range of trucks, SUVs, and performance cars. If you're rebuilding or refreshing the bottom end of one of these popular GM powerplants, a solid set of main bearings is crucial for ensuring the crankshaft spins smoothly and reliably within the engine block.

King Engine Bearings specializes in this exact component, and this set features their PMaxBlack technology, which is a tri-metal copper-based material engineered for superior load capacity. This means the bearings can handle more stress without deforming, which is important for engines that see hard use. They also incorporate Radialock, a design feature that helps maintain optimal crush height during installation, ensuring the bearing stays securely in place and makes good contact with the block and cap.

This set is a well-built option for your GM engine build. It's important to note that these bearings are sized +.020mm, meaning they are meant for crankshaft journals that have been machined down by 0.020 millimeters. Always confirm your crankshaft journal measurements before ordering to ensure you get the correct size for your specific engine build.
