What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to correct wear or out-of-round conditions and achieve proper bearing clearance.

What is the construction of these main bearings?

These main bearings feature a bimetal construction, which means they have an aluminum base. This design is chosen for its ability to handle the operational loads and temperatures within the engine.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required for a complete engine rebuild application for the specified Audi, VW, and Porsche engines.

About this part

Product Details

If you're rebuilding the bottom end of your Audi, VW, or Porsche engine, getting the main bearings right is crucial for smooth operation and longevity. This main bearing set from King Engine Bearings is specifically made for engines like the ABV, AES, and AUE, and it's sized at +0.25mm to help you achieve proper clearances during an engine rebuild.

These bearings are constructed with a bimetal design, meaning they have an aluminum base. This construction helps them handle the loads and temperatures found in these engines. Because they are a +0.25mm size, they are intended for use when the crankshaft journals have been machined down by that amount to correct wear or out-of-round conditions. This set is designed to fit a wide range of vehicles, including models like the Volkswagen Golf, Audi A3, and Porsche Cayenne.
