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

The STDX size indicates that these bearings are 0.001 inch larger in diameter than a standard-sized bearing. This is often used when crankshaft journals have been machined undersize or to achieve a specific, slightly tighter oil clearance.

What is the XP material used in these bearings?

XP stands for Xtreme Performance, which is King's proprietary tri-metal material. It's known for its enhanced strength and ability to withstand higher loads and temperatures compared to standard bearing materials.

Are these bearings a direct replacement for all Audi engines listed?

These bearings are specified for Audi engines with codes CDAA, CDHA, CHHA, CHHB, CJXA, and CJXB. It is always recommended to verify the specific engine code and bearing type required for your vehicle's exact application.

About this part

Product Details

The STDX size designation on this King Engine Bearings main bearing set means these bearings are 0.001 inch larger than standard. This is a critical detail when rebuilding an Audi engine with the CDAA, CDHA, CHHA, CHHB, CJXA, or CJXB engine code, especially if the crankshaft journals have been machined to a specific undersize or if you're looking for a slightly tighter oil clearance than stock.

King uses their XP (Xtreme Performance) material for these bearings, which is a tri-metal material known for its strength and ability to handle higher loads and temperatures. This makes them a solid option for performance builds or when you need a well-built replacement for a worn-out engine. The precision machining ensures they fit right and help maintain proper oil pressure throughout the engine's rotating assembly.
