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 to clean up minor imperfections or wear on the crankshaft.

What is the XP-series material?

The XP-series material is a high-performance overlay developed by King Engine Bearings. It's bonded to a steel-backed bearing and offers improved durability and wear resistance, making it a popular choice for performance applications.

Do these bearings come with installation instructions?

While installation instructions are not typically included with bearing sets, it is highly recommended to refer to the vehicle manufacturer's service manual or a professional mechanic for proper installation procedures and torque specifications.

About this part

Product Details

Built with King's XP-series material, these main bearings are a solid choice for your Ford Zetec engine rebuild. The XP material is a high-performance overlay that's bonded to a steel-backed bearing, offering improved durability and wear resistance compared to standard bearings. This set is specifically sized at +0.25mm, meaning it's intended for use when the crankshaft journals have been machined down by 0.25mm to clean them up or correct minor damage.

When you're rebuilding an engine, especially one like the Ford Zetec found in many 1.6, 1.8, and 2.0 liter applications, getting the bearing clearances just right is critical for oil pressure and engine longevity. These bearings are designed to fit right into your engine, providing the correct oil clearance when used with a properly machined crankshaft. King Engine Bearings is a well-known name in performance and racing circles, and their XP series is a popular option for those looking for a step up in bearing performance without going to a full custom setup.
