What does the 0.5mm undersize mean for my engine?

The 0.5mm undersize indicates that these bearings are slightly smaller than standard. This is typically used when the crankshaft journals have been machined down by 0.5mm to clean up wear or to achieve a specific clearance. Always confirm your crankshaft specifications before ordering.

What is the 'pmax black racing line'?

The pmax black racing line refers to King Engine Bearings' advanced tri-metal material designed for high-performance applications. It offers improved load capacity and friction reduction, making it suitable for engines that experience higher stresses.

Do these bearings come with installation instructions?

While this set includes the bearings, specific installation instructions and torque specifications should be obtained from your vehicle's service manual or the manufacturer's technical documentation to ensure proper fitment and engine health.

About this part

Product Details

If you're rebuilding the bottom end of your BMW M20 or M50 engine, especially for performance applications, a solid set of rod bearings is crucial. This set from King Engine Bearings is designed for those engines displacing 2.0L, 2.5L, or 2.7L, and it comes at a 0.5mm undersize, which is important if you're machining your crankshaft.

These are part of King's pmax black racing line, meaning they use a tri-metal material that's built for higher loads and temperatures often seen in performance builds. The pmax black coating offers improved durability and reduced friction compared to standard bearings. This set fits a wide range of BMW models, including many 3 Series, 5 Series, X3, X5, and Z models from the 1980s through the early 2000s.

When installing these bearings, make sure your crankshaft journals are clean and within the specified tolerance for the 0.5mm undersize. It's always a good idea to refer to your BMW service manual for the correct installation procedures and torque specifications.
