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

The +0.25mm designation indicates that these bearings are undersized by 0.25mm. They are intended for use on crankshaft journals that have been machined down by 0.25mm to correct wear or achieve specific engine clearances.

What is the pmax Black lining?

The pmax Black lining is a tri-metal material often used in racing bearings. It's designed to offer enhanced load capacity and temperature resistance compared to standard bearing materials, making it suitable for performance applications.

Are these bearings a direct replacement for all Alfa Romeo 105 series engines?

These bearings are designed for specific Alfa Romeo models within the 105 series and related platforms, and they are a +0.25mm undersize. Always verify your specific engine's crankshaft journal size and consult your service manual to ensure compatibility and proper installation.

Product Details

These King Engine Bearings connecting rod bearings feature a pmax Black tri-metal lining, a design choice often found in racing applications for its enhanced performance characteristics. They are specifically made for a range of Alfa Romeo models, including the Alfetta, Berlina, and Spider, offering a +0.25mm undersize to help restore proper clearances in engines that have been previously machined.

The pmax Black lining is a notable step up from standard bearings, designed to handle higher loads and temperatures often encountered in performance-oriented engines. This makes them a solid option if you're rebuilding a performance Alfa Romeo engine or looking for a more robust bearing solution than stock replacements. They are an alternative to the CR4421CP race bearings, suggesting a balance between high performance and broader application.

When installing these bearings, remember they are sized +0.25mm undersize. This means they are intended for crankshaft journals that have been turned down by 0.25mm to account for wear or to achieve specific clearances. Always refer to your vehicle's specific service manual for proper installation procedures and torque specifications.
