What does the STDX size mean for these bearings?

The STDX designation indicates that these are an undersize bearing set. This means they are designed to fit a crankshaft that has been machined down by a specific amount, typically to correct for wear or to achieve a specific clearance in an engine build. Always verify your crankshaft journal dimensions before ordering.

What is the material of these bearings?

These bearings are made from a bi-metal aluminum material. They are also lead-free, which is an environmentally safe composite.

Are these bearings suitable for a stock LS engine rebuild?

While these bearings are designed for high performance, they are a popular choice for LS engine builds that may see harder use than a stock application. Their specialized material and construction offer improved durability for engines that are pushed beyond normal driving conditions.

Product Details

If you're rebuilding the bottom end of your Chevy LS engine, getting the right connecting rod bearings is crucial for long-term health and performance. These King Engine Bearings are specifically designed for the LS1 and LS6 engines, but they also fit a wide range of other vehicles, including many Buick, Cadillac, and Chevrolet models from the 80s, 90s, and into the 2000s.

King has been specializing in bearings since 1960, focusing on making the best ones available. These particular bearings use a lead-free, bi-metal aluminum material that's built for high performance. This means they can handle the demands of an engine that's working hard, offering a solid option for your rebuild.

This set is the STDX size, which is a common undersize for engine builds. Always double-check your crankshaft journal size to ensure this is the correct bearing for your specific application.
