Product Details

If you're rebuilding the engine in your 2008-2013 BMW M3, getting the crankshaft main bearings right is crucial for long-term reliability. These are the bearings that support the crankshaft, allowing it to spin smoothly while handling immense forces. King Engine Bearings specializes in this exact component, and their XP Series bearings are built for demanding applications.

These bearings use a tri-metal copper-based material, which is known for its strength and durability. They also feature King's PMaxBlack overlay, an advanced material designed to handle higher loads without deforming. The Radialock feature helps ensure the optimal crush height, which is important for proper seating and oil clearance during installation. This combination makes them a solid option for M3 owners looking for robust engine internals.

When you're putting an engine back together, especially one as high-revving as the S65B40A in your M3, using well-built bearings is key. King has been focused on making bearings since 1960, so they have a lot of experience in this area.
