What does the .020X sizing mean for these bearings?

The .020X designation indicates that these main bearings are undersized by 0.020 inches. They are intended for use with a crankshaft that has been machined down by this amount to ensure a proper fit and oil clearance during an engine rebuild.

What type of Chevrolet engines are these bearings designed for?

This specific bearing set is designed for Chevrolet Gen IV, Gen V, and Gen VI V8 engines. These are common in many performance and heavy-duty applications from the manufacturer.

What is the benefit of the P-shaped groove design?

The P-shaped groove is a design feature that helps to increase the flow of oil to the main bearings. This improved lubrication is critical for reducing friction and wear, especially under demanding engine conditions.

About this part

Product Details

These King Engine Bearings main bearing set features a .020 inch undersize, meaning they are designed to be used with crankshafts that have been machined down by that amount during an engine rebuild. This specific set is built for Chevrolet Gen IV, V, and VI V8 engines, commonly found in many performance and heavy-duty applications. King uses a high-performance overlay with a 10-15% higher fatigue strength than standard materials, which helps these bearings stand up to the demands of a rebuilt or performance engine.

The unique P-shaped groove design on these bearings increases oil flow to the main bearings, helping to keep them properly lubricated under load. This improved oiling is crucial for preventing premature wear and ensuring the longevity of your engine's rotating assembly. They are well-built to handle the stresses of operation, making them a reliable choice for your engine project.
