What does the +0.25mm sizing mean for this main bearing set?

The +0.25mm sizing indicates that these bearings are intended for use when the engine's crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilding to ensure a proper fit with worn or resurfaced journals.

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

This main bearing set is constructed with a bi-metal aluminum material and a lead-free composite, making it ideal for engines that operate under low to medium load conditions. It is not recommended for high-performance or heavy-duty applications.

Does this main bearing set come with installation hardware?

This listing is for the main bearing set only. Installation hardware, such as main bearing bolts or seals, is typically sold separately. Always refer to the manufacturer's installation instructions for a complete list of required components.

Product Details

King Engine Bearings has been specializing in engine bearings since 1960, aiming to supply the highest quality available. This main bearing set, part number MB5270AM0.25, is built with a bi-metal aluminum material and features a lead-free, environmentally safe composite. It's a well-built option for low to medium-load engines.

This set is specifically sized at +0.25mm, meaning it's designed for crankshaft journals that have been machined down by that amount during an engine rebuild.
