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

The +0.25mm sizing means these bearings are intended for use with a crankshaft that has been machined down by 0.25mm. This is typically done to clean up wear or damage on the crankshaft journals.

What is the XP performance material?

XP is a performance material developed by King Engine Bearings. It's designed to offer increased strength and better load-handling capabilities compared to standard bearing materials, suitable for demanding engine applications.

Do these bearings come with installation instructions?

Refer to the manufacturer's installation instructions for details on proper installation procedures. Proper oil clearance is critical when installing bearings sized for a machined crankshaft.

About this part

Product Details

This set includes the main bearings you need for your Suzuki GSXR1000 engine rebuild. These are specifically sized at +0.25mm, meaning they are meant to be used when the crankshaft journals have been machined down by 0.25mm to clean them up or correct wear. Using the correct bearing size is crucial for proper oil clearance, which directly impacts engine oil pressure and longevity.

King Engine Bearings uses their XP performance material for these bearings. This material is known for its strength and ability to handle higher loads and temperatures, making it a solid choice for performance applications or when you want a well-built component for your engine. The +0.25mm sizing means these are not a direct drop-in for a stock crankshaft; the crankshaft must be machined to this specific undersize for them to fit correctly and provide the intended oil clearance.
