What does 'STDX' size mean for these bearings?

The 'STDX' designation indicates that these are undersize bearings. They are designed to be used when the crankshaft journals have been machined down by a specific amount, typically 0.001 inch. It's important to verify your crankshaft journal size before ordering.

What is the PMaxBlack material used in these bearings?

PMaxBlack is King Engine Bearings' proprietary material designed for superior load capacity. This means the bearings can withstand higher pressures and stresses within the engine, contributing to their durability and reliability.

Do these bearings come with installation hardware?

This product is a main bearing set and typically includes only the main bearings themselves. It does not usually come with installation hardware like main cap bolts or oil. Refer to the manufacturer's instructions or consult a mechanic for a complete list of required parts for your engine rebuild.

About this part

Product Details

If you're rebuilding the engine in your Audi or Volkswagen, a solid set of main bearings is crucial. This main bearing set from King Engine Bearings is built for a range of popular models, including the Audi A3, A4, TT, and Volkswagen Beetle, CC, and Jetta. These bearings are a key component in your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly.

King Engine Bearings specializes in this exact part, and they've been doing it since 1960. This particular set features their PMaxBlack material, which is designed for superior load capacity, meaning it can handle the stresses of engine operation reliably. They also incorporate Radialock technology, which helps achieve optimal crush height for a snug fit during installation. The tri-metal copper-based material offers a good balance of strength and conformability, essential for proper oil film formation and wear resistance.

This set is specifically sized STDX, which is an undersize bearing. Always ensure this is the correct size for your crankshaft journals when rebuilding your engine.
