What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are slightly larger than the standard size. This is typically used when the crankshaft journals have experienced some wear and have been machined down, or to achieve specific oil clearance targets during an engine rebuild.

What is Silvercore technology?

Silvercore is a specialized composite material developed by King Engine Bearings. It is designed to handle extreme loads and is based on a tri-metal copper material, offering enhanced durability for high-performance engine applications.

Are these bearings sold individually or as a set?

This is a connecting rod bearing set, meaning it comes with multiple bearings to outfit the required rods for your engine. The product description notes that it comes in pairs, implying enough bearings for a set of connecting rods.

Product Details

If you're rebuilding the engine in your 2008-2013 BMW M3, M5, or M6, these connecting rod bearings from King Engine Bearings are a solid choice. King has been specializing in bearings since 1960, focusing on supplying well-built engine bearings for a range of applications. These specific bearings are designed for BMW's S65B40A and S85B50A engines.

What sets these bearings apart is their construction. They use a tri-metal copper-based material, and feature King's Silvercore technology. This composite is lead-free and built for extreme load capacity, which is crucial for high-performance engines like those found in the M3, M5, and M6. This set is sized at +0.25mm, meaning they are slightly larger than standard to account for crankshaft journal wear or to achieve specific clearances during an engine build.
