What is PMaxBlack technology?

PMaxBlack is a surface treatment used by King Engine Bearings that enhances the bearing's ability to handle superior loads. It's designed to maintain performance under demanding conditions.

What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are intended for use with crankshaft journals that are still at their original factory specifications, without any machining or grinding.

Radialock is a feature designed by King Engine Bearings to help maintain optimal crush height. Proper crush is essential for the bearing to seat correctly in the engine block and maintain oil clearance.

About this part

Product Details

King Engine Bearings has been specializing in engine bearings since 1960, aiming to provide the highest quality available. This main bearing set, part number MB5270XP, is built with a tri-metal copper-based material and features PMaxBlack technology for superior load capacity and Radialock for optimal crush height. These bearings are designed to fit a wide range of vehicles, including popular models like the Dodge Neon SRT4, Chrysler PT Cruiser, and Jeep Liberty.

The tri-metal copper-based construction offers a solid foundation for performance applications, while the PMaxBlack surface treatment is engineered to handle higher loads without compromising the bearing's integrity.
