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

The +0.25mm sizing indicates that these bearings are intended for use on crankshaft connecting rod journals that have been machined down by 0.25mm. This is common during engine rebuilding or when dealing with worn journals.

What is PMaxBlack technology?

PMaxBlack is a proprietary technology from King Engine Bearings designed to enhance the load-carrying capacity of the bearings. This makes them suitable for engines that experience higher stresses or are built for performance applications.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are well-built and feature technologies like PMaxBlack and Radialock that contribute to their durability and performance. They are a solid option for both stock rebuilds and engines with mild performance modifications.

About this part

Product Details

If you're rebuilding the bottom end of your GM or Holden 3.6L engine, especially those with LF4, LFX, or LGX designations, a solid set of connecting rod bearings is crucial. King Engine Bearings has been specializing in these critical components since 1960, aiming to provide the highest quality parts available. This set is designed to be a direct replacement, ensuring a proper fit during your rebuild.

These bearings feature King's PMaxBlack technology, which helps them handle superior load capacities, making them a strong option for engines that see demanding use or are being built for performance. They also incorporate Radialock, a design element that helps achieve optimal crush height, which is important for ensuring the bearing stays securely in place within the connecting rod. The tri-metal copper-based material offers a good balance of strength and conformability, essential for proper oil film formation and wear resistance.

This particular set is sized at +0.25mm, meaning it's intended for crankshaft journals that have been machined down by 0.25mm. Always confirm your journal size before ordering. King Engine Bearings are well-known in the engine building community for their focus on quality and performance.
