What does '0.25mm undersize' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.25mm. This is a common practice during engine rebuilding if the crankshaft journals have wear or have been resurfaced.

What is the main benefit of the bi-metal aluminum material?

The bi-metal aluminum material offers good performance for engines that aren't subjected to extreme racing conditions. It's a well-built material that balances performance with durability for everyday use.

Does this bearing set come with everything needed for installation?

This set includes the main bearings for your engine. You will typically need engine assembly lubricant and other standard engine rebuilding tools and supplies for installation. Always refer to your vehicle's service manual for complete installation procedures.

About this part

Product Details

This is a King Engine Bearings Main Bearing Set, specifically sized at 0.25mm undersize for Mitsubishi 4G93 SOHC engines. You get the main bearings needed to rebuild the bottom end of your engine. These bearings are made with a bi-metal aluminum material, which is a solid choice for engines that don't see extremely heavy loads. King specializes in bearings, focusing on making them well-built to help your engine run smoothly.

The lead-free composite used in these bearings is environmentally safe and works well for many common engine applications. Because they are a specialized component, King focuses on the details that matter for bearing performance. This set is a 0.25mm undersize, meaning it's intended for crankshafts that have been machined down by that amount during an engine rebuild.
