What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are slightly larger than standard. This is necessary when the crankshaft journals have been machined down by 0.010 inches (0.25mm) during an engine rebuild or repair to ensure a proper fit and oil clearance.

What is the PMaxBlack overlay?

PMaxBlack is a proprietary material overlay developed by King Engine Bearings. It is designed to offer enhanced load-carrying capabilities, helping to protect the bearings in high-performance or heavy-duty applications.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit in compatible engines, it is always recommended to refer to the specific vehicle manufacturer's service manual or King Engine Bearings' installation guidelines for proper torque specifications and procedures.

About this part

Product Details

These King Engine Bearings rod bearings are built with a tri-metal copper-based material, a solid foundation for handling the demands of performance engines. They are specifically sized at +0.25mm, which is important when rebuilding or refreshing an engine where the crankshaft journals may have been machined down. This set is designed for Mitsubishi 4G63 and 4G64 6-bolt engines, commonly found in DSM vehicles, and fits a wide range of other applications like the Dodge Colt and Hyundai Sonata.

King uses their PMaxBlack overlay, which is a unique material that offers superior load capacity compared to standard bearings. This helps protect the bearings under higher stress conditions. Additionally, the Radialock feature helps maintain optimal crush height during installation, ensuring the bearing stays securely in place and makes good contact with the connecting rod. This attention to detail in material science and design is what King specializes in, aiming to provide the highest quality bearings available.
