What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds when the crankshaft has been resurfaced due to wear or damage.

What is the King Engine Bearings XP series?

Product Details

This is a set of main bearings from King Engine Bearings, specifically designed for Audi CEPA and CEPB engines. These bearings are sized at +0.25mm, meaning they are intended for use when the crankshaft journals have been machined down by 0.25mm during an engine rebuild. Main bearings are crucial for supporting the crankshaft within the engine block, ensuring it spins smoothly and with minimal friction.

King Engine Bearings are known for their well-built construction. This particular set features their XP series technology, which is designed to handle higher loads and temperatures often found in performance or heavily used engines. The material composition and design help to reduce wear and maintain oil film integrity, which is essential for the longevity of your engine's bottom end. When rebuilding an engine, using bearings that are the correct size and built to last is key to a successful outcome.

If you're rebuilding an Audi CEPA or CEPB engine and have had the crankshaft journals machined to a +0.25mm undersize, this set from King Engine Bearings is a solid option. It's important to ensure your crankshaft journals have been properly measured and machined to this specific size before installing these bearings.
