What does the 1.0mm size mean for these bearings?

The '1.0mm' in the part number indicates that these bearings are 1.0mm larger than standard size. This is used when the crankshaft journals have been machined down (ground undersize) during an engine rebuild to ensure proper oil clearance and a fresh mating surface.

What is the bimetal aluminum base construction?

This bearing features a bimetal construction with an aluminum alloy as the base material. This design is chosen for its good load-carrying capacity and wear resistance, making it suitable for the high-stress environment of an engine's connecting rod journals.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. Typically, engine bearing sets include all the necessary bearings for a specific component, such as all the rod bearings for a complete engine.

About this part

Product Details

Built with a bimetal aluminum base, these connecting rod bearings from King Engine Bearings are designed for a range of Audi and Volkswagen engines. Specifically, they are sized 1.0mm over, which is important when rebuilding or repairing an engine where the crankshaft journals have been machined to this size. This set is intended for models like the Audi 4000, Volkswagen Golf, and Volkswagen Jetta, among many others, offering a solid option for engine work.

The bimetal construction, using an aluminum alloy base, helps these bearings handle the loads and heat generated in an engine. This material choice is common for connecting rod bearings because it offers good wear resistance and conformability to the crankshaft journal. When you're putting an engine back together, especially if it's seen significant mileage or is undergoing a performance build, having well-made bearings like these is crucial for proper oil clearance and long-term reliability.
