What does the 0.25mm undersize mean for my engine rebuild?

The 0.25mm undersize designation means these bearings are slightly smaller than standard size. This is used when the crankshaft journals have been machined down by 0.25mm to correct wear or damage. The undersize bearing compensates for the reduced journal diameter, restoring proper clearances.

What type of engines are these bearings best suited for?

These bearings are specifically designed for low to medium-load engines. They utilize a bi-metal aluminum construction that offers good performance and durability for everyday driving and typical use cases, rather than extreme racing applications.

Are these bearings environmentally safe?

Yes, these King Engine Bearings are made with a lead-free composite material, making them an environmentally safe choice for your engine rebuild.

About this part

Product Details

This is a King Engine Bearings Main Bearing Set, specifically the MB5065AM0.25 part number. You're getting a set of main bearings that are 0.25mm undersize, which is important for engine rebuilding when the crankshaft journals have been machined down to match. These bearings are made with a bi-metal aluminum material, making them a solid option for engines that don't see extremely heavy loads, like those found in many popular Chrysler, Dodge, Mitsubishi, and Plymouth vehicles.

King specializes in bearings, and this set is built with a lead-free composite that's environmentally safe. The bi-metal construction is a common and effective design for main bearings, offering good durability and performance for everyday driving and moderate use. If you're rebuilding the bottom end of a 2.0L engine from a Dodge Neon, Mitsubishi Eclipse, or similar vehicle from the mid-90s to early 2000s, these bearings are designed to fit right in.
