What does the 020X sizing mean for these bearings?

The '020X' in the part number indicates that these bearings are 0.020 inches undersize compared to a standard size bearing. This is a common specification used during engine rebuilding when crankshaft journals have been machined undersize to correct wear or damage.

What is PMaxBlack technology?

PMaxBlack is a proprietary technology developed by King Engine Bearings. It's designed to enhance the load-carrying capabilities of the bearing, making it more robust under high stress conditions common in performance or rebuilt engines.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit in compatible LS engines, it is always recommended to refer to the manufacturer's installation guidelines or a qualified mechanic for proper installation procedures and torque specifications.

About this part

Product Details

If you're rebuilding the bottom end of your Chevrolet LS engine, whether it's a 4.8L, 5.3L, 5.7L, or 6.0L, getting the right rod bearings is crucial for longevity and performance. These performance rod bearings from King Engine Bearings are designed to handle the demands of these popular V8s, offering an improved solution over stock for many applications.

King specializes in bearings, and these are built with a tri-metal copper-based material for solid performance. They feature PMaxBlack technology, which helps increase load capacity, meaning they can better withstand the forces generated during engine operation. The Radialock design helps ensure optimal crush height, which is important for proper seating and sealing within the connecting rod. This set is sized 0.020 inches undersize, which is important to note for your build specifications.

These bearings fit a wide range of vehicles, including many Chevrolet, Buick, and Cadillac models from the late 70s through the early 2010s. Always double-check the fitment for your specific year and model to ensure compatibility.
