What does 0.50mm oversized mean for these main bearings?

This means the bearings are slightly larger than standard size by 0.50 millimeters. This is necessary when the crankshaft journals have been machined down (ground undersize) and then polished back up to this specific size during an engine rebuild.

What is the Manganx strengthening process?

Manganx is a strengthening process King Engine Bearings uses on their aluminum bearing materials. It helps to improve the overall durability and load-carrying capacity of the bearing surface.

Are these bearings compatible with all 1.8/2.0 TSI/TFSI engines?

This specific part number, MB5778SM0.5, is designed for a range of Audi and Volkswagen models equipped with the 1.8L and 2.0L TSI/TFSI engines. Always verify fitment for your specific vehicle year and model using the provided fitment data.

About this part

Product Details

If you're rebuilding the bottom end of your Audi or Volkswagen with a 1.8 or 2.0 TSI/TFSI engine, these main bearings from King Engine Bearings are a solid option. They are specifically sized at 0.50mm oversized, which is important if your crankshaft journals have been machined to this size during a rebuild. King has been specializing in bearings since 1960, focusing on making them as durable as possible.

These main bearings use a bi-metal aluminum material that's strengthened with their Manganx process. This construction helps them stand up to the stresses of engine operation. They are also lead-free, making them an environmentally safer choice. King aims to provide well-built bearings that hold up over time, and this set is designed to fit right into the specified Audi and VW applications.
