What does the 0.50mm oversize mean for these bearings?

The 0.50mm oversize indicates that these bearings are slightly larger than standard size. This is useful when the crankshaft journals have been machined down due to wear or damage, allowing the new bearings to properly fit and maintain correct oil clearance.

What is the construction of these main bearings?

These main bearings are made with a bimetal construction, featuring an aluminum base. This type of bearing material is well-suited for the demands of main bearing applications in engines.

Are these bearings a direct replacement for all Audi 5000 models from 1979-1981?

This specific main bearing set is designed for the 1979-1981 Audi 5000 models equipped with the AAN, AAR, AAT, RT, HY, or NG engine codes. Always confirm your engine code to ensure proper fitment.
