What does the '+0.50mm' mean for these bearings?

The '+0.50mm' indicates that these bearings are 0.50mm undersize. This is typically used when the engine's crankshaft has been machined (ground) down by 0.50mm to ensure a proper fit and oil clearance during an engine rebuild.

What engine codes does this bearing set fit?

This main bearing set is designed for Audi engines with the following codes: AAN, AAR, AAT, RT, HY, and NG.

What is a bimetal bearing?

A bimetal bearing, like this one with an aluminum base, is constructed from two different materials. This design helps manage heat and wear effectively, providing reliable support for the crankshaft.

About this part

Product Details

King Engine Bearings is well-known for making solid engine bearings. If you're rebuilding the bottom end of your 1979-1981 Audi 5000, this main bearing set is a good choice. These bearings are designed to fit the AAN, AAR, AAT, RT, HY, and NG engine codes found in those cars.

This set includes main bearings that are 0.50mm undersize, which is important if you've had your crankshaft ground down to match this size during an engine rebuild. They are constructed with a bimetal design, using an aluminum base for good performance. This means they are built to handle the stresses of keeping your crankshaft properly supported.
