What is the XP high-performance overlay?

The XP overlay is a unique, multi-layer material developed by King Engine Bearings. It incorporates a special high-lead tin-bronze alloy, designed to better handle higher loads and temperatures compared to standard bearings.

What does the 0.026 size mean?

The '.026' in the part number indicates that this is a 0.026 inch undersize bearing set. This means it's intended for use with a crankshaft that has been machined down by 0.026 inches.

What is the benefit of tight tolerances in main bearings?

Tight tolerances are important for maintaining consistent oil clearance around the crankshaft. This ensures proper lubrication and support, which is critical for the longevity and performance of the engine's bottom end.

About this part

Product Details

This King Engine Bearings main bearing set features an XP high-performance overlay, a unique material designed to handle higher loads and temperatures. These bearings are specifically made for Audi engines like the CDAA, CDHA, CHHA, CHHB, CJXA, and CJXB, ensuring they fit correctly in your build. When you're rebuilding the bottom end of one of these engines, getting the main bearings right is crucial for oil pressure and crankshaft support.

The XP overlay is a multi-layer material that includes a special high-lead tin-bronze alloy. This construction helps to reduce friction and wear, especially under demanding conditions. King designs these bearings with tight tolerances, which is important for maintaining consistent oil clearance. Proper oil clearance is key to ensuring the crankshaft has the right amount of lubrication and support to prevent premature wear.

This set is sized at 0.026 inches undersize, which is important to note if you are machining your crankshaft. Always refer to the manufacturer's installation instructions for specific details regarding installation and critical clearances.
