King Engine Bearings Mercedes Benz M 272.911 / M 272.920 (Size 0.5) Crankshaft Main Bearing Set

If you're rebuilding the bottom end of your Mercedes Benz with an M 272.911 or M 272.920 engine, getting the crankshaft main bearings right is crucial for long-term health. These bearings are what the crankshaft spins on within the engine block, and they need to be precise and durable to handle the constant motion and load. King Engine Bearings is a well-known name in this area, offering parts that help ensure your engine runs smoothly and reliably.

This set is specifically sized at 0.5mm undersize, which is important if your crankshaft journals have been machined down during a rebuild or repair. King uses advanced manufacturing techniques to create bearings with a tough overlay and a strong backing, designed to withstand the pressures inside an engine. They focus on creating a consistent surface that helps maintain proper oil clearance, which is key for lubrication and preventing wear.

When you're putting an engine back together, having parts that fit right and perform as expected makes a big difference. This set is intended to be a direct replacement for the original bearings, assuming the crankshaft has been machined to the 0.5mm undersize specification.
