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

The +0.25mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 0.25mm. This is common when a crankshaft has been worn or damaged and needs to be resurfaced to a standard undersize.

What is PMaxBlack and Radialock technology?

PMaxBlack is King's proprietary material designed for superior load capacity, making it suitable for performance applications. Radialock is a feature that helps maintain the optimal crush height of the bearing, ensuring it seats correctly in the engine block.

Do these bearings come with new main bolts?

This product is for the main bearing set only. New main bearing bolts are typically sold separately and are recommended for installation to ensure proper torque and clamping force.

Product Details

If you're rebuilding the bottom end of your engine, a solid set of main bearings is crucial. This set from King Engine Bearings is designed for a range of Chrysler, Dodge, and Plymouth vehicles, including popular models like the Dodge Neon SRT4, Chrysler PT Cruiser, and Jeep Liberty. These bearings are built to handle the demands of performance applications, ensuring your crankshaft spins smoothly and reliably.

King specializes in bearings, and this set features their PMaxBlack material, which offers superior load capacity compared to standard bearings. They also incorporate Radialock technology, designed to maintain optimal crush height for a secure fit and proper oil clearance. The tri-metal copper-based construction provides a strong foundation for durability and performance.
