What is the pMax Black trimetal construction?

The pMax Black trimetal construction is a multi-layer bearing material developed by King Engine Bearings. It's designed to offer improved strength, wear resistance, and heat dissipation compared to standard bearing materials, making it suitable for performance applications.

What does the STDX size mean for these bearings?

STDX indicates that these bearings are 0.001 inch undersize. This sizing is often used when the crankshaft journals have been machined undersize during a rebuild to ensure proper clearance and oil film.

Are these bearings suitable for a stock rebuild?

While these bearings are designed for performance, their improved material properties can also benefit a stock rebuild, especially if the engine sees harder use than typical. Always ensure proper installation and oil clearances are met.

About this part

Product Details

These King Engine Bearings XP-Series rod bearings feature a pMax Black trimetal construction, a design choice that offers improved durability and performance over standard bearings. They are built for Buick V6 engines and fit a wide range of vehicles, including models like the Buick LeSabre, Chevrolet Camaro, and Pontiac Grand Prix. If you're rebuilding the bottom end of your engine, especially for applications that see more demanding use, these bearings are a solid option.

The XP-Series is an updated design from King, offering a step up from their race-specific bearings by incorporating a more robust material. This trimetal construction helps manage heat and friction effectively, which is crucial for maintaining oil pressure and bearing life under load. The STDX size indicates these bearings are 0.001 inch undersize, which can be helpful when dealing with crankshaft journals that have been ground undersize during a rebuild.
