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

The +0.25mm designation means these bearings are slightly larger than standard size. They are intended for use when the crankshaft journals have been machined down by 0.25mm during an engine rebuild or repair.

What type of engine is this bearing set best suited for?

This bearing set is made from a bi-metal aluminum material with a silicon composite, making it ideal for medium-load engines. This means it's well-suited for typical daily driving conditions rather than extreme performance applications.

Are these bearings environmentally friendly?

Yes, these bearings feature a lead-free silicon composite. This makes them an environmentally safer choice compared to bearings that contain lead.

About this part

Product Details

This is a main bearing set from King Engine Bearings, specifically sized at +0.25mm for your 2002-2008 Mini Cooper. These bearings are crucial for the smooth rotation of your engine's crankshaft, supporting it within the engine block. King specializes in bearings, and this set is made from a bi-metal aluminum material that's well-suited for medium-load engines.

The silicon composite used in these bearings is lead-free, making them an environmentally safer option. They are designed to handle the demands of everyday driving and are a solid choice when you're rebuilding or repairing the bottom end of your engine. Because they are a specific size (+0.25mm), they are intended for use when the crankshaft journals have been machined to this undersize.
