What does the .025 size mean for these bearings?

The .025 size indicates that these bearings are undersize by 0.025 inches. This means they are intended for use when the crankshaft has been machined down by that amount to correct wear or damage. Always verify your crankshaft's journal size before purchasing bearings.

What is the pmax black coating?

The pmax black coating is a specialized material applied by King Engine Bearings. It's designed to reduce friction and improve the durability of the bearings, particularly in demanding engine applications.

Do I need to buy anything else to install these bearings?

When replacing main bearings, it's standard practice to also replace the crankshaft main bearing bolts and to use new engine oil and a new oil filter. Always refer to the manufacturer's service manual for the complete list of required parts and procedures.

About this part

Product Details

If you're rebuilding the engine in your BMW M20 or M50, getting the crankshaft spinning true is critical. These King Engine Bearings main bearing set is designed to replace worn bearings in your 2.0L, 2.5L, or 2.7L engine, helping to ensure proper oil clearance and support for the crankshaft. They fit a wide range of BMW models, including popular choices like the E30 325i, E36 325is, and E39 525i.

This set features King's pmax black racing line coating, which is a specialized material applied to help reduce friction and improve durability, especially in high-performance applications. The bearings in this set are .025 inch undersize, meaning they are intended for crankshafts that have been machined down by that amount to correct wear or runout. It's important to confirm your crankshaft's dimensions before ordering to ensure you get the correct size bearing.
