What does the '1.0' size designation mean for these bearings?

The '1.0' in MB5179AM1.0 indicates that these are main bearings that are 1.0mm undersize. This means they are intended for use with a crankshaft that has been machined down by 1.0mm as part of an engine rebuild process.

What is the construction of these main bearings?

These main bearings feature a bimetal construction. They have an aluminum base, which is a common and effective material for engine bearings due to its good compatibility with crankshafts and load-carrying capabilities.

Are these bearings a direct replacement for all vehicles listed?

These bearings are designed as a direct fit for the specified engine codes and vehicle models. However, always confirm your specific engine code and vehicle year to ensure proper fitment for your application, especially if you are not performing a crankshaft regrind.

About this part

Product Details

When you're rebuilding the bottom end of your engine, getting the main bearings right is crucial for smooth operation and longevity. This main bearing set from King Engine Bearings is built for specific Opel engines like the C20XE, X18XE, and X22XE, and it's also designed to fit a range of other vehicles, including some Buick Skyhawks, Chevrolet Malibus, and Pontiac Sunbirds.

These bearings use a bimetal construction with an aluminum base, which is a well-known material for its good load-carrying capacity and compatibility with crankshafts. This particular set is sized 1.0mm undersize, meaning it's intended for crankshafts that have been machined down by that amount during an engine rebuild. King Engine Bearings is a popular name in engine components, and this set is a solid option for anyone looking to replace worn bearings or install new ones during an engine overhaul.
