What does '+1.0mm' mean for these main bearings?

The '+1.0mm' designation means these bearings are 1.0 millimeter larger in diameter than standard size. This is used when the crankshaft journals have been machined down by 1.0mm to remove wear or damage during an engine rebuild.

What kind of engine load is this bearing set designed for?

These bearings are specifically designed for medium-load engines. This typically means they are well-suited for stock or mildly modified engines that are not subjected to extreme stress or high RPMs consistently.

Does this bearing set come with installation instructions?

While this set is designed for a direct fit during a rebuild, it is always recommended to refer to the vehicle manufacturer's service manual or King Engine Bearings' specific installation guidelines for proper torque specifications and procedures.

About this part

Product Details

If you're rebuilding the bottom end of a Chrysler 2.7L engine, you need a solid set of main bearings. This set from King Engine Bearings, part number MB4074SI1.0, is a bi-metal aluminum bearing designed for medium-load applications. It's a +1.0mm undersize set, meaning it's intended for crankshafts that have been machined down by 1.0mm during a rebuild.

King Engine Bearings specializes in making just this kind of part, and they've been doing it since 1960. This particular bearing uses a lead-free composite material that's environmentally safe. The bi-metal construction offers good performance for engines that aren't pushed to extreme limits, making it a popular choice for many stock or mild performance rebuilds.

This set fits a range of Chrysler and Dodge vehicles from the late 90s through 2010, including models like the Chrysler 300, Dodge Charger, and Chrysler Sebring. Always ensure your crankshaft has been properly measured and machined to the correct undersize before installing these bearings.
