What does '0.50mm undersize' mean for these bearings?

This means the bearings are manufactured to be slightly smaller than standard size by 0.50mm. They are intended for use when the crankshaft journals have been machined down by 0.50mm to correct wear or runout.

What kind of engine load is this bearing set best suited for?

This bearing set is ideal for engines that experience low to medium load conditions. It's a good choice for daily drivers or mild performance applications where extreme stress isn't a primary concern.

Are these bearings environmentally safe?

Yes, these bearings utilize a lead-free composite material, making them an environmentally safe option.

About this part

Product Details

What you get here is a set of rod bearings, specifically sized at 0.50mm undersize, for Mitsubishi 4G63 and 4G64 6-bolt first-generation DSM engines. King Engine Bearings has been specializing in these critical engine components since 1960, focusing on supplying well-built bearings to the market. This particular set uses a lead-free composite material that's environmentally safe and well-suited for engines that don't see extreme loads, like many daily drivers or milder performance builds.

The bi-metal aluminum construction is a solid choice for these applications, offering good performance without the need for heavy-duty materials. Because these are an undersize bearing, they are intended for crankshafts that have been machined down by 0.50mm to true them up or account for wear. This ensures a proper, snug fit on the crank journal, which is crucial for oil pressure and bearing longevity.
