What does the .026 size indicate for these bearings?

The .026 size means these bearings are undersize by 0.026 inches. They are intended for use when the crankshaft journals have been machined down to this specific dimension during an engine rebuild.

What is PMaxBlack technology?

PMaxBlack is King Engine Bearings' proprietary technology for their tri-metal copper-based bearings. It's designed to provide superior load capacity, making the bearings more durable under stress.

Do these bearings come with installation instructions?

While this set includes the necessary bearings for your engine, it's recommended to refer to the manufacturer's official installation guidelines or a professional mechanic for proper installation procedures and torque specifications.

About this part

Product Details

When you're rebuilding the bottom end of your BMW M20 or M50 engine, getting the crankshaft main bearings right is crucial for long-term health. This set from King Engine Bearings is specifically made for the 2.0L, 2.5L, and 2.7L displacements found in a range of BMW models, including the 330i, 530i, and X5 from the early 2000s.

King has been specializing in bearings since 1960, and this set uses their PMaxBlack technology, which is a tri-metal copper-based material designed to handle higher loads. The Radialock feature helps ensure the optimal crush height, which is important for proper seating and oil control. This set is also .026 inches undersize, meaning it's intended for crankshafts that have been machined to that specific dimension during a rebuild.

This set includes 7 pairs of bearings, covering all the main journals for your engine. Make sure to check your crankshaft's specifications to confirm it has been machined to the .026 undersize before ordering.
