What does the 'STDX' size mean for these bearings?

The 'STDX' designation indicates that these bearings are 0.001 inch undersize compared to standard main bearings. This sizing is used when the crankshaft journals have been machined down to a specific undersize to correct wear or for a performance build.

What is the advantage of King's high-performance overlay material?

King's special overlay material is well-built for durability and can better withstand the high loads and stresses placed on the crankshaft during engine operation. This helps to extend the life of the bearings and the engine.

Do these bearings come with installation instructions?

While specific installation instructions are not included with the bearings themselves, it is critical to refer to the manufacturer's official service manual for your Audi CEPA or CEPB engine. Proper cleaning of journals and block surfaces, along with correct torque specifications, are essential for a successful installation.

About this part

Product Details

When you're rebuilding the bottom end of your Audi with a CEPA or CEPB engine, getting the crankshaft main bearings right is crucial. These King Engine Bearings are specifically made to support the crankshaft, ensuring it spins smoothly and stays properly aligned within the engine block. Getting this part of the rebuild done correctly means the difference between a quiet, long-lasting engine and one that develops issues down the road.

These are the STDX size bearings, which means they are 0.001 inch undersize. This is important if your crankshaft journals have been ground down slightly during a previous rebuild or to correct wear. King uses a special high-performance overlay material that's known for its durability and ability to handle the stresses of engine operation. They also incorporate a unique flashing process that helps to improve oil flow and reduce friction, which is key for keeping your engine cool and preventing premature wear.

For a successful engine build, it's important to ensure your crankshaft journals are clean and within the specified tolerances for the STDX size before installing these bearings. Proper installation is key to their performance and longevity.
